gcloud ai-platform local train

NAME
gcloud ai-platform local train - run an AI Platform training job locally
SYNOPSIS
gcloud ai-platform local train --module-name=MODULE_NAME [--distributed] [--job-dir=JOB_DIR] [--package-path=PACKAGE_PATH] [--parameter-server-count=PARAMETER_SERVER_COUNT] [--start-port=START_PORT; default=27182] [--worker-count=WORKER_COUNT] [GCLOUD_WIDE_FLAG] [-- USER_ARGS …]
DESCRIPTION
This command runs the specified module in an environment similar to that of a live AI Platform Training Job.

This is especially useful in the case of testing distributed models, as it allows you to validate that you are properly interacting with the AI Platform cluster configuration. If your model expects a specific number of parameter servers or workers (i.e. you expect to use the CUSTOM machine type), use the --parameter-server-count and --worker-count flags to further specify the desired cluster configuration, just as you would in your cloud training job configuration:

  $ gcloud ai-platform local train --module-name trainer.task \
          --package-path /path/to/my/code/trainer \
          --distributed \
          --parameter-server-count 4 \
          --worker-count 8

Unlike submitting a training job, the --package-path parameter can be omitted, and will use your current working directory.

POSITIONAL ARGUMENTS
[-- USER_ARGS …]
Additional user arguments to be forwarded to user code. Any relative paths will be relative to the parent directory of --package-path. The '--' argument must be specified between gcloud specific args on the left and USER_ARGS on the right.
REQUIRED FLAGS
--module-name=MODULE_NAME
Name of the module to run.
OPTIONAL FLAGS
--distributed
Runs the provided code in distributed mode by providing cluster configurations as environment variables to subprocesses
--job-dir=JOB_DIR
Google Cloud Storage path or local_directory in which to store training outputs and other data needed for training.

This path will be passed to your TensorFlow program as the --job_dir command-line arg. The benefit of specifying this field is that AI Platform will validate the path for use in training.

--package-path=PACKAGE_PATH
Path to a Python package to build. This should point to a directory containing the Python source for the job. It will be built using setuptools (which must be installed) using its parent directory as context. If the parent directory contains a setup.py file, the build will use that; otherwise, it will use a simple built-in one.
--parameter-server-count=PARAMETER_SERVER_COUNT
Number of parameter servers with which to run. Ignored if --distributed is not specified. Default: 2
--start-port=START_PORT; default=27182
Start of the range of ports reserved by the local cluster. This command will use a contiguous block of ports equal to parameter-server-count + worker-count + 1.

If --distributed is not specified, this flag is ignored.

--worker-count=WORKER_COUNT
Number of workers with which to run. Ignored if --distributed is not specified. Default: 2
GCLOUD WIDE FLAGS
These flags are available to all commands: --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.
