Can ted policy use distributed training ? #10911

Closed vietnguyen012 closed 1 year ago

vietnguyen012 commented 2 years ago

What problem are you trying to solve?

I'm trying to use multiple gpus to optimize ted policy during training time.

What's your suggested solution?

At first, I tried to add mirrored strategy to training function of ted policy. Below is the run_training in ted_policy.py, I added a segment where I use mirrored strategy and the old segment which uses only one gpu.

Examples (if relevant)

def run_training( self, model_data: RasaModelData, label_ids: Optional[np.ndarray] = None ) -> None: """Feeds the featurized training data to the model.

Args: model_data: Featurized training data. label_ids: Label ids corresponding to the data points in model_data. These may or may not be used by the function depending on how the policy is trained. """

  1. os.environ.pop('TF_CONFIG', None)

  2. tf_config = {

  3. 'cluster': { # 'worker': ['localhost:12345', 'localhost:23456'] # }

    ,

  4. 'task': {'type': 'worker', 'index': 0}

  5. }

  6. os.environ['TF_CONFIG'] = json.dumps(tf_config)

  7. tf_config = json.loads(os.environ['TF_CONFIG'])

  8. num_workers = len(tf_config['cluster']['worker']) if not self.finetune_mode:

  9. This means the model wasn't loaded from a

  10. previously trained model and hence needs

  11. to be instantiated. self.model = self.model_class()( model_data.get_signature(), self.config, isinstance(self.featurizer, MaxHistoryTrackerFeaturizer), self._label_data, self._entity_tag_specs, ) self.model.compile( optimizer=tf.keras.optimizers.Adam(self.config[LEARNING_RATE]) ) ( data_generator, validation_data_generator, ) = rasa.utils.train_utils.create_data_generators( model_data, self.config[BATCH_SIZES], self.config[EPOCHS], self.config[BATCH_STRATEGY], self.config[EVAL_NUM_EXAMPLES], self.config[RANDOM_SEED], ) callbacks = rasa.utils.train_utils.create_common_callbacks( self.config[EPOCHS], self.config[TENSORBOARD_LOG_DIR], self.config[TENSORBOARD_LOG_LEVEL], self.tmp_checkpoint_dir, ) self.model.fit( data_generator, epochs=self.config[EPOCHS], validation_data=validation_data_generator, validation_freq=self.config[EVAL_NUM_EPOCHS], callbacks=callbacks, verbose=False, shuffle=False, # we use custom shuffle inside data generator )

    global_batch_size = self.config[BATCH_SIZES]*2

  12. tf.debugging.set_log_device_placement(True) gpus = tf.config.list_logical_devices('GPU') strategy = tf.distribute.MirroredStrategy(gpus)

    if not self.finetune_mode:

  13. This means the model wasn't loaded from a

  14. previously trained model and hence needs

  15. to be instantiated. with strategy.scope(): self.model = self.model_class()( model_data.get_signature(), self.config, isinstance(self.featurizer, MaxHistoryTrackerFeaturizer), self._label_data, self._entity_tag_specs, ) self.model.compile( optimizer=tf.keras.optimizers.Adam(self.config[LEARNING_RATE]) )

    ( data_generator, validation_data_generator, ) = rasa.utils.train_utils.create_data_generators( model_data, global_batch_size, self.config[EPOCHS], self.config[BATCH_STRATEGY], self.config[EVAL_NUM_EXAMPLES], self.config[RANDOM_SEED], ) callbacks = rasa.utils.train_utils.create_common_callbacks( self.config[EPOCHS], self.config[TENSORBOARD_LOG_DIR], self.config[TENSORBOARD_LOG_LEVEL], self.tmp_checkpoint_dir, ) self.model.fit( data_generator, epochs=self.config[EPOCHS], validation_data=validation_data_generator, validation_freq=self.config[EVAL_NUM_EPOCHS], callbacks=callbacks, verbose=False, shuffle=False, # we use custom shuffle inside data generator

The first run without mirrored strategy is okay but when running with mirrored strategy, there is a conflict in ted model. I can't figure out where is the cause of it (the distributed training makes it very hard to debug).

Is anything blocking this from being implemented? (if relevant)
