Release History

7.0.0b1 (2021-06-02)

This is beta preview version. For detailed changelog please refer to equivalent stable version 2.0.0(https://pypi.org/project/azure-mgmt-batchai/2.0.0/)

This version uses a next-generation code generator that introduces important breaking changes, but also important new features (like unified authentication and async programming).

General breaking changes

Credential system has been completly revamped:
- azure.common.credentials or msrestazure.azure_active_directory instances are no longer supported, use the azure-identity classes instead: https://pypi.org/project/azure-identity/
- credentials parameter has been renamed credential
The config attribute no longer exists on a client, configuration should be passed as kwarg. Example: MyClient(credential, subscription_id, enable_logging=True). For a complete set of supported options, see the parameters accept in init documentation of azure-core
You can't import a version module anymore, use __version__ instead
Operations that used to return a msrest.polling.LROPoller now returns a azure.core.polling.LROPoller and are prefixed with begin_.
Exceptions tree have been simplified and most exceptions are now azure.core.exceptions.HttpResponseError (CloudError has been removed).
Most of the operation kwarg have changed. Some of the most noticeable:
- raw has been removed. Equivalent feature can be found using cls, a callback that will give access to internal HTTP response for advanced user
- For a complete set of supported options, see the parameters accept in Request documentation of azure-core

General new features

Type annotations support using typing. SDKs are mypy ready.
This client has now stable and official support for async. Check the aio namespace of your package to find the async client.
This client now support natively tracing library like OpenCensus or OpenTelemetry. See this tracing quickstart for an overview.

2.0.0 (2018-06-07)

Breaking changes

This version uses 2018-05-01 BatchAI API specification which introduced the following braking changes:

Clusters, FileServers must be created under a workspace;
Jobs must be created under an experiment;
Clusters, FileServers and Jobs do not accept location during creation and belong to the same location as the parent workspace;
Clusters, FileServers and Jobs do not support tags;
BatchAIManagementClient.usage renamed to BatchAIManagementClient.usages;
Job priority changed a type from int to an enum;
File.is_directory is replaced with File.file_type;
Job.priority and JobCreateParameters.priority is replaced with scheduling_priority;
Removed unsupported MountSettings.file_server_type attribute;
OutputDirectory.type unsupported attribute removed;
OutputDirectory.create_new attributes removed, BatchAI will always create output directories if they not exist;
SetupTask.run_elevated attribute removed, the setup task is always executed under root.

Features

Added support to workspaces to group Clusters, FileServers and Experiments and remove limit on number of allocated resources;
Added support for experiment to group jobs and remove limit on number of jobs;
Added support for configuring /dev/shm for jobs which use docker containers;
Added first class support for generic MPI jobs;
Added first class support for Horovod jobs.

1.0.0 (2018-03-19)

General Breaking changes

This version uses a next-generation code generator that might introduce breaking changes.

Model signatures now use only keyword-argument syntax. All positional arguments must be re-written as keyword-arguments. To keep auto-completion in most cases, models are now generated for Python 2 and Python 3. Python 3 uses the "*" syntax for keyword-only arguments.
Enum types now use the "str" mixin (class AzureEnum(str, Enum)) to improve the behavior when unrecognized enum values are encountered. While this is not a breaking change, the distinctions are important, and are documented here: https://docs.python.org/3/library/enum.html#others At a glance:
- "is" should not be used at all.
- "format" will return the string value, where "%s" string formatting will return NameOfEnum.stringvalue. Format syntax should be prefered.
New Long Running Operation:
- Return type changes from msrestazure.azure_operation.AzureOperationPoller to msrest.polling.LROPoller. External API is the same.
- Return type is now always a msrest.polling.LROPoller, regardless of the optional parameters used.
- The behavior has changed when using raw=True. Instead of returning the initial call result as ClientRawResponse, without polling, now this returns an LROPoller. After polling, the final resource will be returned as a ClientRawResponse.
- New polling parameter. The default behavior is Polling=True which will poll using ARM algorithm. When Polling=False, the response of the initial call will be returned without polling.
- polling parameter accepts instances of subclasses of msrest.polling.PollingMethod.
- add_done_callback will no longer raise if called after polling is finished, but will instead execute the callback right away.
