|
||||
### Quick installation
|
||||
We recommend you create a Python virtual environment ([Miniconda](https://conda.io/miniconda.html) preferred but [virtualenv](https://virtualenv.pypa.io/en/latest/) works too) and install the SDK in it.
|
||||
```sh
|
||||
# install just the base SDK
|
||||
pip install azureml-sdk
|
||||
|
||||
# clone the sample repoistory
|
||||
git clone https://github.com/Azure/MachineLearningNotebooks.git
|
||||
|
||||
# below steps are optional
|
||||
# install the base SDK and a Jupyter notebook server
|
||||
pip install azureml-sdk[notebooks]
|
||||
|
||||
# install the data prep component
|
||||
pip install azureml-dataprep
|
||||
|
||||
# install model explainability component
|
||||
pip install azureml-sdk[explain]
|
||||
|
||||
# install automated ml components
|
||||
pip install azureml-sdk[automl]
|
||||
|
||||
# install experimental features (not ready for production use)
|
||||
pip install azureml-sdk[contrib]
|
||||
```
|
||||
|
||||
Note the _extras_ (the keywords inside the square brackets) can be combined. For example:
|
||||
```sh
|
||||
# install base SDK, Jupyter notebook and automated ml components
|
||||
pip install azureml-sdk[notebooks,automl]
|
||||
```
|
||||
|
||||
### Full instructions
|
||||
[Install the Azure Machine Learning SDK](https://docs.microsoft.com/en-us/azure/machine-learning/service/quickstart-create-workspace-with-python)
|
||||
|
||||
Please make sure you start with the [Configuration](configuration.ipynb) notebook to create and connect to a workspace.
|
||||
|
||||
|
||||
### Video walkthrough:
|
||||
|
||||
[](https://youtu.be/VIsXeTuW3FU)
|
||||
|
||||
1. Setup a Jupyter Notebook server and [install the Azure Machine Learning SDK](https://docs.microsoft.com/en-us/azure/machine-learning/service/quickstart-create-workspace-with-python)
|
||||
1. Clone [this repository](https://aka.ms/aml-notebooks)
|
||||
1. You may need to install other packages for specific notebook
|
||||
- For example, to run the Azure Machine Learning Data Prep notebooks, install the extra dataprep SDK:
|
||||
```bash
|
||||
pip install azureml-dataprep
|
||||
```
|
||||
|
||||
1. Start your notebook server
|
||||
1. Follow the instructions in the [Configuration](configuration.ipynb) notebook to create and connect to a workspace
|
||||
1. Open one of the sample notebooks
|
||||
## **Option 3: Use Docker**
|
||||
|
||||
You need to have Docker engine installed locally and running. Open a command line window and type the following command.
|
||||
|
||||
__Note:__ We use version `1.0.10` below as an exmaple, but you can replace that with any available version number you like.
|
||||
|
||||
```sh
|
||||
# clone the sample repoistory
|
||||
git clone https://github.com/Azure/MachineLearningNotebooks.git
|
||||
|
||||
# change current directory to the folder
|
||||
# where Dockerfile of the specific SDK version is located.
|
||||
cd MachineLearningNotebooks/Dockerfiles/1.0.10
|
||||
|
||||
# build a Docker image with the a name (azuremlsdk for example)
|
||||
# and a version number tag (1.0.10 for example).
|
||||
# this can take several minutes depending on your computer speed and network bandwidth.
|
||||
docker build . -t azuremlsdk:1.0.10
|
||||
|
||||
# launch the built Docker container which also automatically starts
|
||||
# a Jupyter server instance listening on port 8887 of the host machine
|
||||
docker run -it -p 8887:8887 azuremlsdk:1.0.10
|
||||
```
|
||||
|
||||
Now you can point your browser to http://localhost:8887. We recommend that you start from the `configuration.ipynb` notebook at the root directory.
|
||||
|
||||
If you need additional Azure ML SDK components, you can either modify the Docker files before you build the Docker images to add additional steps, or install them through command line in the live container after you build the Docker image. For example:
|
||||
|
||||
```sh
|
||||
# install dataprep components
|
||||
pip install azureml-dataprep
|
||||
|
||||
# install the core SDK and automated ml components
|
||||
pip install azureml-sdk[automl]
|
||||
|
||||
# install the core SDK and model explainability component
|
||||
pip install azureml-sdk[explain]
|
||||
|
||||
# install the core SDK and experimental components
|
||||
pip install azureml-sdk[contrib]
|
||||
```

## How to use the RAPIDS on AzureML materials
|
||||
### Setting up requirements
|
||||
The material requires the use of the Azure ML SDK and of the Jupyter Notebook Server to run the interactive execution. Please refer to instructions to [setup the environment.](https://docs.microsoft.com/en-us/azure/machine-learning/service/how-to-configure-environment#local "Local Computer Set Up") Follow the instructions under **Local Computer**, make sure to run the last step: <span style="font-family: Courier New;">pip install \<new package\></span> with <span style="font-family: Courier New;">new package = progressbar2 (pip install progressbar2)</span>
|
||||
|
||||
After following the directions, the user should end up setting a conda environment (<span style="font-family: Courier New;">myenv</span>)that can be activated in an Anaconda prompt
|
||||
|
||||
The user would also require an Azure Subscription with a Machine Learning Services quota on the desired region for 24 nodes or more (to be able to select a vmSize with 4 GPUs as it is used on the Notebook) on the desired VM family ([NC\_v3](https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sizes-gpu#ncv3-series), [NC\_v2](https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sizes-gpu#ncv2-series), [ND](https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sizes-gpu#nd-series) or [ND_v2](https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sizes-gpu#ndv2-series-preview)), the specific vmSize to be used within the chosen family would also need to be whitelisted for Machine Learning Services usage.
|
||||
|
||||
|
||||
### Getting and running the material
|
||||
Clone the AzureML Notebooks repository in GitHub by running the following command on a local_directory:
|
||||
|
||||
* C:\local_directory>git clone https://github.com/Azure/MachineLearningNotebooks.git
|
||||
|
||||
On a conda prompt navigate to the local directory, activate the conda environment (<span style="font-family: Courier New;">myenv</span>), where the Azure ML SDK was installed and launch Jupyter Notebook.
|
||||
|
||||
* (<span style="font-family: Courier New;">myenv</span>) C:\local_directory>jupyter notebook
|
||||
|
||||
From the resulting browser at http://localhost:8888/tree, navigate to the master notebook:
|
||||
|
||||
* http://localhost:8888/tree/MachineLearningNotebooks/contrib/RAPIDS/azure-ml-with-nvidia-rapids.ipynb
|
||||
|
||||
|
||||
The following notebook will appear:
|
||||
|
||||

|
||||
|
||||
|
||||
### Master Jupyter Notebook
|
||||
The notebook can be executed interactively step by step, by pressing the Run button (In a red circle in the above image.)
|
||||
|
||||
The first couple of functional steps import the necessary AzureML libraries. If you experience any errors please refer back to the [setup the environment.](https://docs.microsoft.com/en-us/azure/machine-learning/service/how-to-configure-environment#local "Local Computer Set Up") instructions.
|
||||
|
||||
|
||||
#### Setting up a Workspace
|
||||
The following step gathers the information necessary to set up a workspace to execute the RAPIDS script. This needs to be done only once, or not at all if you already have a workspace you can use set up on the Azure Portal:
|
||||
|
||||

|
||||
|
||||
|
||||
It is important to be sure to set the correct values for the subscription\_id, resource\_group, workspace\_name, and region before executing the step. An example is:
|
||||
|
||||
subscription_id = os.environ.get("SUBSCRIPTION_ID", "1358e503-xxxx-4043-xxxx-65b83xxxx32d")
|
||||
resource_group = os.environ.get("RESOURCE_GROUP", "AML-Rapids-Testing")
|
||||
workspace_name = os.environ.get("WORKSPACE_NAME", "AML_Rapids_Tester")
|
||||
workspace_region = os.environ.get("WORKSPACE_REGION", "West US 2")
|
||||
|
||||
|
||||
The resource\_group and workspace_name could take any value, the region should match the region for which the subscription has the required Machine Learning Services node quota.
|
||||
|
||||
The first time the code is executed it will redirect to the Azure Portal to validate subscription credentials. After the workspace is created, its related information is stored on a local file so that this step can be subsequently skipped. The immediate step will just load the saved workspace
|
||||
|
||||

|
||||
|
||||
Once a workspace has been created the user could skip its creation and just jump to this step. The configuration file resides in:
|
||||
|
||||
* C:\local_directory\\MachineLearningNotebooks\contrib\RAPIDS\aml_config\config.json
|
||||
|
||||
|
||||
#### Creating an AML Compute Target
|
||||
Following step, creates an AML Compute Target
|
||||
|
||||

|
||||
|
||||
Parameter vm\_size on function call AmlCompute.provisioning\_configuration() has to be a member of the VM families ([NC\_v3](https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sizes-gpu#ncv3-series), [NC\_v2](https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sizes-gpu#ncv2-series), [ND](https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sizes-gpu#nd-series) or [ND_v2](https://docs.microsoft.com/en-us/azure/virtual-machines/windows/sizes-gpu#ndv2-series-preview)) that are the ones provided with P40 or V100 GPUs, that are the ones supported by RAPIDS. In this particular case an Standard\_NC24s\_V2 was used.
|
||||
|
||||
|
||||
If the output of running the step has an error of the form:
|
||||
|
||||

|
||||
|
||||
It is an indication that even though the subscription has a node quota for VMs for that family, it does not have a node quota for Machine Learning Services for that family.
|
||||
You will need to request an increase node quota for that family in that region for **Machine Learning Services**.
|
||||
|
||||
|
||||
Another possible error is the following:
|
||||
|
||||

|
||||
|
||||
Which indicates that specified vmSize has not been whitelisted for usage on Machine Learning Services and a request to do so should be filled.
|
||||
|
||||
The successful creation of the compute target would have an output like the following:
|
||||
|
||||

|
||||
|
||||
#### RAPIDS script uploading and viewing
|
||||
The next step copies the RAPIDS script process_data.py, which is a slightly modified implementation of the [RAPIDS E2E example](https://github.com/rapidsai/notebooks/blob/master/mortgage/E2E.ipynb), into a script processing folder and it presents its contents to the user. (The script is discussed in the next section in detail).
|
||||
If the user wants to use a different RAPIDS script, the references to the <span style="font-family: Courier New;">process_data.py</span> script have to be changed
|
||||
|
||||

|
||||
|
||||
#### Data Uploading
|
||||
The RAPIDS script loads and extracts features from the Fannie Mae’s Mortgage Dataset to train an XGBoost prediction model. The script uses two years of data
|
||||
|
||||
The next few steps download and decompress the data and is made available to the script as an [Azure Machine Learning Datastore](https://docs.microsoft.com/en-us/azure/machine-learning/service/how-to-access-data).
|
||||
|
||||
|
||||
The following functions are used to download and decompress the input data
|
||||
|
||||
|
||||

|
||||

|
||||

|
||||

|
||||
|
||||
|
||||
The next step uses those functions to download locally file:
|
||||
http://rapidsai-data.s3-website.us-east-2.amazonaws.com/notebook-mortgage-data/mortgage_2000-2001.tgz'
|
||||
And to decompress it, into local folder path = .\mortgage_2000-2001
|
||||
The step takes several minutes, the intermediate outputs provide progress indicators.
|
||||
|
||||

|
||||
|
||||
|
||||
The decompressed data should have the following structure:
|
||||
* .\mortgage_2000-2001\acq\Acquisition_<year>Q<num>.txt
|
||||
* .\mortgage_2000-2001\perf\Performance_<year>Q<num>.txt
|
||||
* .\mortgage_2000-2001\names.csv
|
||||
|
||||
The data is divided in partitions that roughly correspond to yearly quarters. RAPIDS includes support for multi-node, multi-GPU deployments, enabling scaling up and out on much larger dataset sizes. The user will be able to verify that the number of partitions that the script is able to process increases with the number of GPUs used. The RAPIDS script is implemented for single-machine scenarios. An example supporting multiple nodes will be published later.
|
||||
|
||||
|
||||
The next step upload the data into the [Azure Machine Learning Datastore](https://docs.microsoft.com/en-us/azure/machine-learning/service/how-to-access-data) under reference <span style="font-family: Courier New;">fileroot = mortgage_2000-2001</span>
|
||||
|
||||
The step takes several minutes to load the data, the output provides a progress indicator.
|
||||
|
||||

|
||||
|
||||
Once the data has been loaded into the Azure Machine LEarning Data Store, in subsequent run, the user can comment out the ds.upload line and just make reference to the <span style="font-family: Courier New;">mortgage_2000-2001</blog> data store reference
|
||||
|
||||
|
||||
#### Setting up required libraries and environment to run RAPIDS code
|
||||
There are two options to setup the environment to run RAPIDS code. The following steps shows how to ues a prebuilt conda environment. A recommended alternative is to specify a base Docker image and package dependencies. You can find sample code for that in the notebook.
|
||||
|
||||

|
||||
|
||||
|
||||
#### Wrapper function to submit the RAPIDS script as an Azure Machine Learning experiment
|
||||
|
||||
The next step consists of the definition of a wrapper function to be used when the user attempts to run the RAPIDS script with different arguments. It takes as arguments: <span style="font-family: Times New Roman;">*cpu\_training*</span>; a flag that indicates if the run is meant to be processed with CPU-only, <span style="font-family: Times New Roman;">*gpu\_count*</span>; the number of GPUs to be used if they are meant to be used and part_count: the number of data partitions to be used
|
||||
|
||||

|
||||
|
||||
|
||||
The core of the function resides in configuring the run by the instantiation of a ScriptRunConfig object, which defines the source_directory for the script to be executed, the name of the script and the arguments to be passed to the script.
|
||||
In addition to the wrapper function arguments, two other arguments are passed: <span style="font-family: Times New Roman;">*data\_dir*</span>, the directory where the data is stored and <span style="font-family: Times New Roman;">*end_year*</span> is the largest year to use partition from.
|
||||
|
||||
|
||||
As mentioned earlier the size of the data that can be processed increases with the number of gpus, in the function, dictionary <span style="font-family: Times New Roman;">*max\_gpu\_count\_data\_partition_mapping*</span> maps the maximum number of partitions that we empirically found that the system can handle given the number of GPUs used. The function throws a warning when the number of partitions for a given number of gpus exceeds the maximum but the script is still executed, however the user should expect an error as an out of memory situation would be encountered
|
||||
If the user wants to use a different RAPIDS script, the reference to the process_data.py script has to be changed
|
||||
|
||||
|
||||
#### Submitting Experiments
|
||||
We are ready to submit experiments: launching the RAPIDS script with different sets of parameters.
|
||||
|
||||
|
||||
The following couple of steps submit experiments under different conditions.
|
||||
|
||||

|
||||
|
||||
|
||||
The user can change variable num\_gpu between one and the number of GPUs supported by the chosen vmSize. Variable part\_count can take any value between 1 and 11, but if it exceeds the maximum for num_gpu, the run would result in an error
|
||||
|
||||
|
||||
If the experiment is successfully submitted, it would be placed on a queue for processing, its status would appeared as Queued and an output like the following would appear
|
||||
|
||||

|
||||
|
||||
|
||||
When the experiment starts running, its status would appeared as Running and the output would change to something like this:
|
||||
|
||||

|
||||
|
||||
|
||||
#### Reproducing the performance gains plot results on the Blog Post
|
||||
When the run has finished successfully, its status would appeared as Completed and the output would change to something like this:
|
||||
|
||||
|
||||

|
||||
|
||||
Which is the output for an experiment run with three partitions and one GPU, notice that the reported processing time is 49.16 seconds just as depicted on the performance gains plot on the blog post
|
||||
|
||||
|
||||
|
||||

|
||||
|
||||
|
||||
This output corresponds to a run with three partitions and two GPUs, notice that the reported processing time is 37.50 seconds just as depicted on the performance gains plot on the blog post
|
||||
|
||||
|
||||

|
||||
|
||||
This output corresponds to an experiment run with three partitions and three GPUs, notice that the reported processing time is 24.40 seconds just as depicted on the performance gains plot on the blog post
|
||||
|
||||
|
||||

|
||||
|
||||
This output corresponds to an experiment run with three partitions and four GPUs, notice that the reported processing time is 23.33 seconds just as depicted on the performance gains plot on the blogpost
|
||||
|
||||
|
||||

|
||||
|
||||
This output corresponds to an experiment run with three partitions and using only CPU, notice that the reported processing time is 9 minutes and 1.21 seconds or 541.21 second just as depicted on the performance gains plot on the blog post
|
||||
|
||||
|
||||

|
||||
|
||||
This output corresponds to an experiment run with nine partitions and four GPUs, notice that the notebook throws a warning signaling that the number of partitions exceed the maximum that the system can handle with those many GPUs and the run ends up failing, hence having and status of Failed.
|
||||
|
||||
|
||||
##### Freeing Resources
|
||||
In the last step the notebook deletes the compute target. (This step is optional especially if the min_nodes in the cluster is set to 0 with which the cluster will scale down to 0 nodes when there is no usage.)
|
||||
|
||||

|
||||
|
||||
|
||||
### RAPIDS Script
|
||||
The Master Notebook runs experiments by launching a RAPIDS script with different sets of parameters. In this section, the RAPIDS script, process_data.py in the material, is analyzed
|
||||
|
||||
The script first imports all the necessary libraries and parses the arguments passed by the Master Notebook.
|
||||
|
||||
The all internal functions to be used by the script are defined.
|
||||
|
||||
|
||||
#### Wrapper Auxiliary Functions:
|
||||
The below functions are wrappers for a configuration module for librmm, the RAPIDS Memory Manager python interface:
|
||||
|
||||

|
||||
|
||||
|
||||
A couple of other functions are wrappers for the submission of jobs to the DASK client:
|
||||
|
||||

|
||||

|
||||
|
||||
|
||||
#### Data Loading Functions:
|
||||
The data is loaded through the use of the following three functions
|
||||
|
||||

|
||||
|
||||
All three functions use library function cudf.read_csv(), cuDF version for the well known counterpart on Pandas.
|
||||
|
||||
|
||||
#### Data Transformation and Feature Extraction Functions:
|
||||
The raw data is transformed and processed to extract features by joining, slicing, grouping, aggregating, factoring, etc, the original dataframes just as is done with Pandas. The following functions in the script are used for that purpose:
|
||||

|
||||
|
||||

|
||||
|
||||
|
||||
#### Main() Function
|
||||
The previous functions are used in the Main function to accomplish several steps: Set up the Dask client, do all ETL operations, set up and train an XGBoost model, the function also assigns which data needs to be processed by each Dask client
|
||||
|
||||
|
||||
##### Setting Up DASK client:
|
||||
The following lines:
|
||||
|
||||

|
||||
|
||||
|
||||
Initialize and set up a DASK client with a number of workers corresponding to the number of GPUs to be used on the run. A successful execution of the set up will result on the following output:
|
||||
|
||||

|
||||
|
||||
##### All ETL functions are used on single calls to process\_quarter_gpu, one per data partition
|
||||
|
||||

|
||||
|
||||
|
||||
##### Concentrating the data assigned to each DASK worker
|
||||
The partitions assigned to each worker are concatenated and set up for training.
|
||||
|
||||

|
||||
|
||||
|
||||
##### Setting Training Parameters
|
||||
The parameters used for the training of a gradient boosted decision tree model are set up in the following code block:
|
||||

|
||||
|
||||
Notice how the parameters are modified when using the CPU-only mode.
|
||||
|
||||
|
||||
##### Launching the training of a gradient boosted decision tree model using XGBoost.
|
||||
|
||||

|
||||
|
||||
The outputs of the script can be observed in the master notebook as the script is executed

"The [RAPIDS](https://www.developer.nvidia.com/rapids) suite of software libraries from NVIDIA enables the execution of end-to-end data science and analytics pipelines entirely on GPUs. In many machine learning projects, a significant portion of the model training time is spent in setting up the data; this stage of the process is known as Extraction, Transformation and Loading, or ETL. By using the DataFrame API for ETLÂ and GPU-capable ML algorithms in RAPIDS, data preparation and training models can be done in GPU-accelerated end-to-end pipelines without incurring serialization costs between the pipeline stages.

## Cross validation split options
|
||||
### K-Folds Cross Validation
|
||||
Use *n_cross_validations* setting to specify the number of cross validations. The training data set will be randomly split into *n_cross_validations* folds of equal size. During each cross validation round, one of the folds will be used for validation of the model trained on the remaining folds. This process repeats for *n_cross_validations* rounds until each fold is used once as validation set. Finally, the average scores accross all *n_cross_validations* rounds will be reported, and the corresponding model will be retrained on the whole training data set.
|
||||
|
||||
### Monte Carlo Cross Validation (a.k.a. Repeated Random Sub-Sampling)
|
||||
Use *validation_size* to specify the percentage of the training data set that should be used for validation, and use *n_cross_validations* to specify the number of cross validations. During each cross validation round, a subset of size *validation_size* will be randomly selected for validation of the model trained on the remaining data. Finally, the average scores accross all *n_cross_validations* rounds will be reported, and the corresponding model will be retrained on the whole training data set.
|
||||
|
||||
### Custom train and validation set
|
||||
You can specify seperate train and validation set either through the get_data() or directly to the fit method.

## Data pre-processing and featurization
|
||||
If you use `preprocess=True`, the following data preprocessing steps are performed automatically for you:
|
||||
|
||||
1. Dropping high cardinality or no variance features
|
||||
- Features with no useful information are dropped from training and validation sets. These include features with all values missing, same value across all rows or with extremely high cardinality (e.g., hashes, IDs or GUIDs).
|
||||
2. Missing value imputation
|
||||
- For numerical features, missing values are imputed with average of values in the column.
|
||||
- For categorical features, missing values are imputed with most frequent value.
|
||||
3. Generating additional features
|
||||
- For DateTime features: Year, Month, Day, Day of week, Day of year, Quarter, Week of the year, Hour, Minute, Second.
|
||||
- For Text features: Term frequency based on bi-grams and tri-grams, Count vectorizer.
|
||||
4. Transformations and encodings
|
||||
- Numeric features with very few unique values are transformed into categorical features.
|
||||
See [Configure automated machine learning experiments](https://docs.microsoft.com/azure/machine-learning/service/how-to-configure-auto-train) to learn how more about the the settings and features available for automated machine learning experiments.

## automl_setup fails
|
||||
1. On windows, make sure that you are running automl_setup from an Anconda Prompt window rather than a regular cmd window. You can launch the "Anaconda Prompt" window by hitting the Start button and typing "Anaconda Prompt". If you don't see the application "Anaconda Prompt", you might not have conda or mini conda installed. In that case, you can install it [here](https://conda.io/miniconda.html)
|
||||
2. Check that you have conda 4.4.10 or later. You can check the version with the command `conda -V`. If you have a previous version installed, you can update it using the command: `conda update conda`.
|
||||
3. Pass a new name as the first parameter to automl_setup so that it creates a new conda environment. You can view existing conda environments using `conda env list` and remove them with `conda env remove -n <environmentname>`.

1. On Windows, make sure that you are running automl_setup from an Anconda Prompt window rather than a regular cmd window. You can launch the "Anaconda Prompt" window by hitting the Start button and typing "Anaconda Prompt". If you don't see the application "Anaconda Prompt", you might not have conda or mini conda installed. In that case, you can install it [here](https://conda.io/miniconda.html)
|
||||
2. Check that you have conda 64-bit installed rather than 32-bit. You can check this with the command `conda info`. The `platform` should be `win-64` for Windows or `osx-64` for Mac.
|
||||
3. Check that you have conda 4.4.10 or later. You can check the version with the command `conda -V`. If you have a previous version installed, you can update it using the command: `conda update conda`.
|
||||
4. On Linux, if the error is `gcc: error trying to exec 'cc1plus': execvp: No such file or directory`, install build essentials using the command `sudo apt-get install build-essential`.
|
||||
5. Pass a new name as the first parameter to automl_setup so that it creates a new conda environment. You can view existing conda environments using `conda env list` and remove them with `conda env remove -n <environmentname>`.
|
||||
|
||||
## automl_setup_linux.sh fails
|
||||
If automl_setup_linux.sh fails on Ubuntu Linux with the error: `unable to execute 'gcc': No such file or directory`
|
||||
1. Make sure that outbound ports 53 and 80 are enabled. On an Azure VM, you can do this from the Azure Portal by selecting the VM and clicking on Networking.
|
||||
2. Run the command: `sudo apt-get update`
|
||||
3. Run the command: `sudo apt-get install build-essential --fix-missing`
|
||||
4. Run `automl_setup_linux.sh` again.

|
||||
1) Check that you have selected correct kernel in jupyter notebook. The kernel is displayed in the top right of the notebook page. It can be changed using the `Kernel | Change Kernel` menu option. For Azure Notebooks, it should be `Python 3.6`. For local conda environments, it should be the conda envioronment name that you specified in automl_setup. The default is azure_automl. Note that the kernel is saved as part of the notebook. So, if you switch to a new conda environment, you will have to select the new kernel in the notebook.
|
||||
2) Check that the notebook is for the SDK version that you are using. You can check the SDK version by executing `azureml.core.VERSION` in a jupyter notebook cell. You can download previous version of the sample notebooks from GitHub by clicking the `Branch` button, selecting the `Tags` tab and then selecting the version.

## Numpy import fails on Windows
|
||||
Some Windows environments see an error loading numpy with the latest Python version 3.6.8. If you see this issue, try with Python version 3.6.7.
|
||||
|
||||
## Numpy import fails
|
||||
Check the tensorflow version in the automated ml conda environment. Supported versions are < 1.13. Uninstall tensorflow from the environment if version is >= 1.13
|
||||
You may check the version of tensorflow and uninstall as follows
|
||||
1) start a command shell, activate conda environment where automated ml packages are installed
|
||||
2) enter `pip freeze` and look for `tensorflow` , if found, the version listed should be < 1.13
|
||||
3) If the listed version is a not a supported version, `pip uninstall tensorflow` in the command shell and enter y for confirmation.

|
||||
## Remote run: DsvmCompute.create fails
|
||||
There are several reasons why the DsvmCompute.create can fail. The reason is usually in the error message but you have to look at the end of the error message for the detailed reason. Some common reasons are:
|
||||
1) `Compute name is invalid, it should start with a letter, be between 2 and 16 character, and only include letters (a-zA-Z), numbers (0-9) and \'-\'.` Note that underscore is not allowed in the name.

A time column is required for forecasting, while the grain is optional. If a grain is not given, AutoML assumes that the whole dataset is a single time-series. We also pass a list of columns to drop prior to modeling. The _logQuantity_ column is completely correlated with the target quantity, so it must be removed to prevent a target leak.\n",

In this example, we set the maximum horizon to the number of samples per series in the test set (n_test_periods). Generally, the value of this parameter will be dictated by business needs. For example, a demand planning organizaion that needs to estimate the next month of sales would set the horizon accordingly. \n",

"Finally, a note about the cross-validation (CV) procedure for time-series data. AutoML uses out-of-sample error estimates to select a best pipeline/model, so it is important that the CV fold splitting is done correctly. Time-series can violate the basic statistical assumptions of the canonical K-Fold CV strategy, so AutoML implements a [rolling origin validation](https://robjhyndman.com/hyndsight/tscv/) procedure to create CV folds for time-series data. To use this procedure, you just need to specify the desired number of CV folds in the AutoMLConfig object. It is also possible to bypass CV and use your own validation set by setting the *X_valid* and *y_valid* parameters of AutoMLConfig.\n",

We also provide a stopping metric indicating a target for the primary metrics so that AutoML can terminate the run without necessarly going through all the iterations. Finally, if you want to avoid a certain pipeline, we allow you to specify a blacklist of algorithms that AutoML will ignore for this run.\n",
