# Azure Machine Learning Python SDK notebooks
|
||||
|
||||
This repository contains example notebooks demonstrating the [Azure Machine Learning](https://azure.microsoft.com/en-us/services/machine-learning-service/) Python SDK which allows you to build, train, deploy and manage machine learning solutions using Azure. The AML SDK allows you the choice of using local or cloud compute resources, while managing and maintaining the complete data science workflow from the cloud.
|
||||
> a community-driven repository of examples using mlflow for tracking can be found at https://github.com/Azure/azureml-examples
|
||||
|
||||

|
||||
Welcome to the Azure Machine Learning Python SDK notebooks repository!
|
||||
|
||||
## Quick installation
|
||||
```sh
|
||||
pip install azureml-sdk
|
||||
```
|
||||
Read more detailed instructions on [how to set up your environment](./NBSETUP.md) using Azure Notebook service, your own Jupyter notebook server, or Docker.
|
||||
## Getting started
|
||||
|
||||
## How to navigate and use the example notebooks?
|
||||
If you are using an Azure Machine Learning Notebook VM, you are all set. Otherwise, you should always run the [Configuration](./configuration.ipynb) notebook first when setting up a notebook library on a new machine or in a new environment. It configures your notebook library to connect to an Azure Machine Learning workspace, and sets up your workspace and compute to be used by many of the other examples.
|
||||
These notebooks are recommended for use in an Azure Machine Learning [Compute Instance](https://docs.microsoft.com/azure/machine-learning/concept-compute-instance), where you can run them without any additional set up.
|
||||
|
||||
If you want to...
|
||||
However, the notebooks can be run in any development environment with the correct `azureml` packages installed.
|
||||
|
||||
* ...try out and explore Azure ML, start with image classification tutorials: [Part 1 (Training)](./tutorials/img-classification-part1-training.ipynb) and [Part 2 (Deployment)](./tutorials/img-classification-part2-deploy.ipynb).
|
||||
* ...prepare your data and do automated machine learning, start with regression tutorials: [Part 1 (Data Prep)](./tutorials/regression-part1-data-prep.ipynb) and [Part 2 (Automated ML)](./tutorials/regression-part2-automated-ml.ipynb).
|
||||
* ...learn about experimentation and tracking run history, first [train within Notebook](./how-to-use-azureml/training/train-within-notebook/train-within-notebook.ipynb), then try [training on remote VM](./how-to-use-azureml/training/train-on-remote-vm/train-on-remote-vm.ipynb) and [using logging APIs](./how-to-use-azureml/training/logging-api/logging-api.ipynb).
|
||||
* ...train deep learning models at scale, first learn about [Machine Learning Compute](./how-to-use-azureml/training/train-on-amlcompute/train-on-amlcompute.ipynb), and then try [distributed hyperparameter tuning](./how-to-use-azureml/training-with-deep-learning/train-hyperparameter-tune-deploy-with-pytorch/train-hyperparameter-tune-deploy-with-pytorch.ipynb) and [distributed training](./how-to-use-azureml/training-with-deep-learning/distributed-pytorch-with-horovod/distributed-pytorch-with-horovod.ipynb).
|
||||
* ...deploy models as a realtime scoring service, first learn the basics by [training within Notebook and deploying to Azure Container Instance](./how-to-use-azureml/training/train-within-notebook/train-within-notebook.ipynb), then learn how to [register and manage models, and create Docker images](./how-to-use-azureml/deployment/register-model-create-image-deploy-service/register-model-create-image-deploy-service.ipynb), and [production deploy models on Azure Kubernetes Cluster](./how-to-use-azureml/deployment/production-deploy-to-aks/production-deploy-to-aks.ipynb).
|
||||
* ...deploy models as a batch scoring service, first [train a model within Notebook](./how-to-use-azureml/training/train-within-notebook/train-within-notebook.ipynb), learn how to [register and manage models](./how-to-use-azureml/deployment/register-model-create-image-deploy-service/register-model-create-image-deploy-service.ipynb), then [create Machine Learning Compute for scoring compute](./how-to-use-azureml/training/train-on-amlcompute/train-on-amlcompute.ipynb), and [use Machine Learning Pipelines to deploy your model](https://aka.ms/pl-batch-scoring).
|
||||
* ...monitor your deployed models, learn about using [App Insights](./how-to-use-azureml/deployment/enable-app-insights-in-production-service/enable-app-insights-in-production-service.ipynb) and [model data collection](./how-to-use-azureml/deployment/enable-data-collection-for-models-in-aks/enable-data-collection-for-models-in-aks.ipynb).
|
||||
|
||||
## Tutorials

"This notebook shows how to use [Fairlearn (an open source fairness assessment and unfairness mitigation package)](http://fairlearn.org) and Azure Machine Learning Studio for a binary classification problem. This example uses the well-known adult census dataset. For the purposes of this notebook, we shall treat this as a loan decision problem. We will pretend that the label indicates whether or not each individual repaid a loan in the past. We will use the data to train a predictor to predict whether previously unseen individuals will repay a loan or not. The assumption is that the model predictions are used to decide whether an individual should be offered a loan. Its purpose is purely illustrative of a workflow including a fairness dashboard - in particular, we do **not** include a full discussion of the detailed issues which arise when considering fairness in machine learning. For such discussions, please [refer to the Fairlearn website](http://fairlearn.org/).\n",

There were package changes in automated machine learning version 1.0.76, which require the previous version to be uninstalled before upgrading to the new version.
|

If you have manually upgraded from a version of automated machine learning before 1.0.76 to 1.0.76 or later, you may get the error:

## Remote run: DsvmCompute.create fails
|
||||
## KeyError: 'brand' when running AutoML on local compute or Azure Databricks cluster**
|
||||
If a new environment was created after 10 June 2020 using SDK 1.7.0 or lower, training may fail with the above error due to an update in the py-cpuinfo package. (Environments created on or before 10 June 2020 are unaffected, as well as experiments run on remote compute as cached training images are used.) To work around this issue, either of the two following steps can be taken:
|
||||
|
||||
1) Update the SDK version to 1.8.0 or higher (this will also downgrade py-cpuinfo to 5.0.0):
|
||||
`pip install --upgrade azureml-sdk[automl]`
|
||||
|
||||
2) Downgrade the installed version of py-cpuinfo to 5.0.0:
|
||||
`pip install py-cpuinfo==5.0.0`
|
||||
|
||||
## 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.
|
||||
2) `The requested VM size xxxxx is not available in the current region.` You can select a different region or vm_size.

## Remote run: Iterations show as "Not Responding" in the RunDetails widget.
|

This can be caused by too many concurrent iterations for a remote DSVM. Each concurrent iteration usually takes 100% of a core when it is running. Some iterations can use multiple cores. So, the max_concurrent_iterations setting should always be less than the number of cores of the DSVM.

# Experimental Notebooks for Automated ML
|
||||
Notebooks listed in this folder are leveraging experimental features. Namespaces or function signitures may change in future SDK releases. The notebooks published here will reflect the latest supported APIs. All of these notebooks can run on a client-only installation of the Automated ML SDK.
|
||||
The client only installation doesn't contain any of the machine learning libraries, such as scikit-learn, xgboost, or tensorflow, making it much faster to install and is less likely to conflict with any packages in an existing environment. However, since the ML libraries are not available locally, models cannot be downloaded and loaded directly in the client. To replace the functionality of having models locally, these notebooks also demonstrate the ModelProxy feature which will allow you to submit a predict/forecast to the training environment.
|
||||
|
||||
<a name="localconda"></a>
|
||||
## Setup using a Local Conda environment
|
||||
|
||||
To run these notebook on your own notebook server, use these installation instructions.
|
||||
The instructions below will install everything you need and then start a Jupyter notebook.
|
||||
If you would like to use a lighter-weight version of the client that does not install all of the machine learning libraries locally, you can leverage the [experimental notebooks.](experimental/README.md)
|
||||
|
||||
### 1. Install mini-conda from [here](https://conda.io/miniconda.html), choose 64-bit Python 3.7 or higher.
|
||||
- **Note**: if you already have conda installed, you can keep using it but it should be version 4.4.10 or later (as shown by: conda -V). If you have a previous version installed, you can update it using the command: conda update conda.
|
||||
There's no need to install mini-conda specifically.
|
||||
|
||||
### 2. Downloading the sample notebooks
|
||||
- Download the sample notebooks from [GitHub](https://github.com/Azure/MachineLearningNotebooks) as zip and extract the contents to a local directory. The automated ML sample notebooks are in the "automated-machine-learning" folder.
|
||||
|
||||
### 3. Setup a new conda environment
|
||||
The **automl_setup_thin_client** script creates a new conda environment, installs the necessary packages, configures the widget and starts a jupyter notebook. It takes the conda environment name as an optional parameter. The default conda environment name is azure_automl_experimental. The exact command depends on the operating system. See the specific sections below for Windows, Mac and Linux. It can take about 10 minutes to execute.
|
||||
|
||||
Packages installed by the **automl_setup** script:
|
||||
<ul><li>python</li><li>nb_conda</li><li>matplotlib</li><li>numpy</li><li>cython</li><li>urllib3</li><li>pandas</li><li>azureml-sdk</li><li>azureml-widgets</li><li>pandas-ml</li></ul>
|
||||
|
||||
For more details refer to the [automl_env_thin_client.yml](./automl_env_thin_client.yml)
|
||||
## Windows
|
||||
Start an **Anaconda Prompt** window, cd to the **how-to-use-azureml/automated-machine-learning/experimental** folder where the sample notebooks were extracted and then run:
|
||||
```
|
||||
automl_setup_thin_client
|
||||
```
|
||||
## Mac
|
||||
Install "Command line developer tools" if it is not already installed (you can use the command: `xcode-select --install`).
|
||||
|
||||
Start a Terminal windows, cd to the **how-to-use-azureml/automated-machine-learning/experimental** folder where the sample notebooks were extracted and then run:
|
||||
|
||||
```
|
||||
bash automl_setup_thin_client_mac.sh
|
||||
```
|
||||
|
||||
## Linux
|
||||
cd to the **how-to-use-azureml/automated-machine-learning/experimental** folder where the sample notebooks were extracted and then run:
|
||||
|
||||
```
|
||||
bash automl_setup_thin_client_linux.sh
|
||||
```
|
||||
|
||||
### 4. Running configuration.ipynb
|
||||
- Before running any samples you next need to run the configuration notebook. Click on [configuration](../../configuration.ipynb) notebook
|
||||
- Execute the cells in the notebook to Register Machine Learning Services Resource Provider and create a workspace. (*instructions in notebook*)
|
||||
|
||||
### 5. Running Samples
|
||||
- Please make sure you use the Python [conda env:azure_automl_experimental] kernel when trying the sample Notebooks.
|
||||
- Follow the instructions in the individual notebooks to explore various features in automated ML.
|
||||
|
||||
### 6. Starting jupyter notebook manually
|
||||
To start your Jupyter notebook manually, use:
|
||||
|
||||
```
|
||||
conda activate azure_automl
|
||||
jupyter notebook
|
||||
```
|
||||
|
||||
or on Mac or Linux:
|
||||
|
||||
```
|
||||
source activate azure_automl
|
||||
jupyter notebook
|
||||
```

# Running using python command
|
||||
Jupyter notebook provides a File / Download as / Python (.py) option for saving the notebook as a Python file.
|
||||
You can then run this file using the python command.
|
||||
However, on Windows the file needs to be modified before it can be run.
|
||||
The following condition must be added to the main code in the file:
|
||||
|
||||
if __name__ == "__main__":
|
||||
|
||||
The main code of the file must be indented so that it is under this condition.

The prediction will happen on same compute and environment that was used to train the model. This feature is currently in the experimental state, which means that the API is prone to changing, please make sure to run on the latest version of this notebook if you face any issues.\n",
