## 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.

# Troubleshooting
|
||||
## Iterations fail and the log contains "MemoryError"
|
||||
This can be caused by insufficient memory on the DSVM. AutoML loads all training data into memory. So, the available memory should be more than the training data size.
|
||||
If you are using a remote DSVM, memory is needed for each concurrent iteration. The concurrent_iterations setting specifies the maximum concurrent iterations. For example, if the training data size is 8Gb and concurrent_iterations is set to 10, the minimum memory required is at least 80Gb.
|
||||
To resolve this issue, allocate a DSVM with more memory or reduce the value specified for concurrent_iterations.

|

|

## 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 concurrent_iterations setting should always be less than the number of cores of the DSVM.
|
||||
To resolve this issue, try reducing the value specified for the concurrent_iterations setting.

**PREVIEW capability**
|
||||
|
||||
Automated ML now supports Azure Databricks as a local compute to perform training (**public preview**). Azure Databricks is a managed Spark offering on Azure and customers already use it for advanced analytics. It provides a collaborative Notebook based environment with CPU or GPU based compute cluster.
|
||||
- Customers who use Azure Databricks for advanced analytics can now use the same cluster to run automated machine learning experiments.
|
||||
- You can keep the data within the same cluster.
|
||||
- You can leverage the local worker nodes with autoscale and auto termination capabilities.
|
||||
- You can use multiple cores of your Azure Databricks cluster to perform simultenous training.
|
||||
- You can further tune the model generated by automated machine learning if you chose to.
|
||||
- Every run (including the best run) is available as a pipeline.
|
||||
- The model from the pipeline can be registered in Azure ML SDK workspace and then deployed to Azure managed compute (ACI or AKS) using the Azure Machine learning SDK.
|
||||
|
||||
**Create Azure Databricks Cluster:**
|
||||
|
||||
Select New Cluster and fill in following detail:
|
||||
- Cluster name: _yourclustername_
|
||||
- Cluster Mode: Any. **High Concurrency** preferred
|
||||
- Databricks Runtime: Any 4.x runtime.
|
||||
- Python version: **3**
|
||||
- Workers: 2 or higher.
|
||||
- Max. number of **concurrent iterations** in Automated ML settings is **<=** to the number of **worker nodes** in your Databricks cluster.
|
||||
- Worker node VM types: **Memory optimized VM** preferred.
|
||||
- Uncheck _Enable Autoscaling_
|
||||
|
||||
|
||||
It will take few minutes to create the cluster. Please ensure that the cluster state is running before proceeding further.
|
||||
|
||||
**Install Azure ML with Automated ML SDK on your Azure Databricks cluster**
|
||||
|
||||
- Select Import library
|
||||
|
||||
- Source: Upload Python Egg or PyPI
|
||||
|
||||
- PyPi Name (_with_ Automated ML capability): **azureml-sdk[automl_databricks]**
|
||||
|
||||
- PyPi Name (_without_ Automated ML capability): **azureml-sdk[databricks]**
|
||||
|
||||
- Click Install Library
|
||||
|
||||
- Do not select _Attach automatically to all clusters_. In case you have selected earlier then you can go to your Home folder and deselect it.
|
||||
|
||||
- Select the check box _Attach_ next to your cluster name
|
||||
|
||||
(More details on how to attach and detach libs are here - [https://docs.databricks.com/user-guide/libraries.html#attach-a-library-to-a-cluster](https://docs.databricks.com/user-guide/libraries.html#attach-a-library-to-a-cluster) )
|
||||
|
||||
- Ensure that there are no errors until Status changes to _Attached_. It may take a couple of minutes.
|
||||
|
||||
**Note** - If you have the old build the please deselect it from cluster’s installed libs > move to trash. Install the new build and restart the cluster. And if still there is an issue then detach and reattach your cluster.
|
||||
|
||||
**Now you can run the Automated ML sample notebook on your Azure Databricks cluster. Please let us know your feedback.**

# Azure Machine Learning Pipeline
|
||||
|
||||
## Overview
|
||||
|
||||
The [Azure Machine Learning Pipelines](https://docs.microsoft.com/en-us/azure/machine-learning/service/concept-ml-pipelines) enables data scientists to create and manage multiple simple and complex workflows concurrently. A typical pipeline would have multiple tasks to prepare data, train, deploy and evaluate models. Individual steps in the pipeline can make use of diverse compute options (for example: CPU for data preparation and GPU for training) and languages.
|
||||
|
||||
The Python-based Azure Machine Learning Pipeline SDK provides interfaces to work with Azure Machine Learning Pipelines. To get started quickly, the SDK includes imperative constructs for sequencing and parallelization of steps. With the use of declarative data dependencies, optimized execution of the tasks can be achieved. The SDK can be easily used from Jupyter Notebook or any other preferred IDE. The SDK includes a framework of pre-built modules for common tasks such as data transfer and compute provisioning.
|
||||
|
||||
Data management and reuse across pipelines and pipeline runs is simplified using named and strictly versioned data sources and named inputs and outputs for processing tasks. Pipelines enable collaboration across teams of data scientists by recording all intermediate tasks and data.
|
||||
|
||||
### Why build pipelines?
|
||||
|
||||
With pipelines, you can optimize your workflow with simplicity, speed, portability, and reuse. When building pipelines with Azure Machine Learning, you can focus on what you know best — machine learning — rather than infrastructure.
|
||||
|
||||
Using distinct steps makes it possible to rerun only the steps you need as you tweak and test your workflow. Once the pipeline is designed, there is often more fine-tuning around the training loop of the pipeline. When you rerun a pipeline, the execution jumps to the steps that need to be rerun, such as an updated training script, and skips what hasn't changed. The same paradigm applies to unchanged scripts and metadata.
|
||||
|
||||
With Azure Machine Learning, you can use distinct toolkits and frameworks for each step in your pipeline. Azure coordinates between the various compute targets you use so that your intermediate data can be shared with the downstream compute targets easily.
|
||||
|
||||
|
||||
|
||||
|
||||
### Azure Machine Learning Pipelines Features
|
||||
Azure Machine Learning Pipelines optimize for simplicity, speed, and efficiency. The following key concepts make it possible for a data scientist to focus on ML rather than infrastructure.
|
||||
|
||||
**Unattended execution**: Schedule a few scripts to run in parallel or in sequence in a reliable and unattended manner. Since data prep and modeling can last days or weeks, you can now focus on other tasks while your pipeline is running.
|
||||
|
||||
**Mixed and diverse compute**: Use multiple pipelines that are reliably coordinated across heterogeneous and scalable computes and storages. Individual pipeline steps can be run on different compute targets, such as HDInsight, GPU Data Science VMs, and Databricks, to make efficient use of available compute options.
|
||||
|
||||
**Reusability**: Pipelines can be templatized for specific scenarios such as retraining and batch scoring. They can be triggered from external systems via simple REST calls.
|
||||
|
||||
**Tracking and versioning**: Instead of manually tracking data and result paths as you iterate, use the pipelines SDK to explicitly name and version your data sources, inputs, and outputs as well as manage scripts and data separately for increased productivity.
|
||||
|
||||
### Notebooks
|
||||
|
||||
In this directory, there are two types of notebooks:
|
||||
|
||||
* The first type of notebooks will introduce you to core Azure Machine Learning Pipelines features. The notebooks below belong in this category, and are designed to go in sequence:
|
||||
|
||||
1. [aml-pipelines-getting-started.ipynb](aml-pipelines-getting-started.ipynb)
|
||||
2. [aml-pipelines-with-data-dependency-steps.ipynb](aml-pipelines-with-data-dependency-steps.ipynb)
|
||||
3. [aml-pipelines-publish-and-run-using-rest-endpoint.ipynb](aml-pipelines-publish-and-run-using-rest-endpoint.ipynb)
|
||||
4. [aml-pipelines-data-transfer.ipynb](aml-pipelines-data-transfer.ipynb)
|
||||
5. [aml-pipelines-use-databricks-as-compute-target.ipynb](aml-pipelines-use-databricks-as-compute-target.ipynb)
|
||||
6. [aml-pipelines-use-adla-as-compute-target.ipynb](aml-pipelines-use-adla-as-compute-target.ipynb)
|
||||
|
||||
* The second type of notebooks illustrate more sophisticated scenarios, and are independent of each other. These notebooks include:
|
||||
- [pipeline-batch-scoring.ipynb](pipeline-batch-scoring.ipynb)
|
||||
- [pipeline-style-transfer.ipynb](pipeline-style-transfer.ipynb)
