NAME
gcloud beta ml-engine local train - run an AI Platform training job locally
SYNOPSIS
gcloud beta ml-engine local train --module-name=MODULE_NAME [--distributed]
[--evaluator-count=EVALUATOR_COUNT] [--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
(BETA) 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 beta ml-engine 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.
AI Platform Training sets a TF_CONFIG environment variable on each VM in
your training job. You can use TF_CONFIG to access the cluster description
and the task description for each VM.
Learn more about TF_CONFIG:
https://cloud.google.com/ai-platform/training/docs/distributed-training-details.
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
--evaluator-count=EVALUATOR_COUNT
Number of evaluators with which to run. Ignored if --distributed is not
specified. Default: 0
--job-dir=JOB_DIR
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. However, note that
your training program will need to parse the provided --job-dir
argument.
--package-path=PACKAGE_PATH
Path to a Python package to build. This should point to a local
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: --access-token-file, --account,
--billing-project, --configuration, --flags-file, --flatten, --format,
--help, --impersonate-service-account, --log-http, --project, --quiet,
--trace-token, --user-output-enabled, --verbosity.
Run $ gcloud help for details.
NOTES

variants are also available:
