What does this PR do?
This PR makes the
dataset
attribute optional for thePPOTrainer
to simplify the API. Currently one needs to create a Dataset class in order to initialize thePPOTrainer
. We can make things simpler by making this attribute optional.Though the
PPOTrainer
training loop relies heavily on theconfig.batch_size
attribute, I suggest to warn users to make sure that they have setconfig.batch_size
to the correct batch_size before running anythingAlso updated and tested the script on the REAMDE
