Description

Hi

I started the learning a few minutes ago and this is what I got in command prompt:

E:\agents>python -m agents.scripts.train --logdir=E:\model --config=pendulum
INFO:tensorflow:Start a new run and write summaries and checkpoints to E:\model\
20170918T084053-pendulum.
WARNING:tensorflow:Number of agents should divide episodes per update.

It's been like this for about 10 minutes and tensorboard doesn't show anything. In the log directory, there is only one file called 'config.yaml'. Is it ok? It would be nice to see if the agent is progressing or it is hung or something.

Thanks Amin

Research direction
The issue describes a hang on Windows when running training. Investigate TensorFlow threading behavior on Windows, particularly with respect to file I/O or process spawning. Check comments for any solutions or workarounds. Look into the agents/scripts/train.py file and related modules for threading or queue initialization that might block on Windows due to missing fork support or different default behavior.
