absl-extra 0.0.3.dev14

A wrapper to run and monitor absl app.

ABSL-Extra

A collection of utils I commonly use for running my experiments. It will:

• Notify on execution start, finish or failed.
  • By default, Notifier will just log those out to stdout.
  • I prefer receiving those in Slack, though (see example below).
• Log parsed CLI flags from absl.flags.FLAGS and config values from config_file:get_config()
• Inject pymongo.collection.Collection if mongo_config kwarg provided.
• Select registered task to run based on --task= CLI argument.

Minimal example

import os
from pymongo.collection import Collection
from ml_collections import ConfigDict
from absl import logging
import tensorflow as tf

from absl_extra import tf_utils, tasks, notifier


@tasks.register_task(
    mongo_config=dict(uri=os.environ["MONGO_URI"], db_name="my_project", collection="experiment_1"),
    notifier=notifier.SlackNotifier(slack_token=os.environ["SLACK_BOT_TOKEN"], channel_id=os.environ["CHANNEL_ID"])
)
@tf_utils.requires_gpu
def main(config: ConfigDict, db: Collection) -> None:
    if tf_utils.supports_mixed_precision():
        tf.keras.mixed_precision.set_global_policy("mixed_float16")
    
    with tf_utils.make_gpu_strategy().scope():
        logging.info("Doing some heavy lifting...")


if __name__ == "__main__":
    tasks.run()
