Custom path for ~/ray_results without using Tune

RLlib
1

How severe does this issue affect your experience of using Ray?

  • Medium: It contributes to significant difficulty to complete my task, but I can work around it.

Just as the title says, I need to store the logs that are stored in ~/ray_results by default, somewhere else instead.

I found an old post that doesn’t really work for my purpose anymore: python - Change Logdir of Ray RLlib Training instead of ~/ray_results - Stack Overflow

This shouldn’t be such a complex thing to do, so I have come here seeking help. I just need to save the ~/ray_results elsewhere so I can access them and actually process them. I have a PPOConfig() object that I used to build() my algo object in code. I’m guessing there should be some option relating to the path in PPOConfig().debugging() maybe? I don’t know. Please advise.

I solved it in the next way:

from ray.tune.logger import UnifiedLogger
def logger_creator(config):
    return UnifiedLogger(config, EXP_FOLDER_NAME, loggers=None)

config.build(logger_creator=logger_creator)
