DQN.py training demo code error

[cedwards77]

The example code works great for 'eva'l and 'play' tasks, but when I tried running the training example, I'm getting errors such 'TypeError: step() missing 1 required positional argument: 'isOver'.

Here is the command that I used:
python DQN.py --task train --algo DQN --gpu 0 --files './data/filenames/image_files.txt' './data/filenames/landmark_files.txt'

Any help you could provide is greatly appreciated! I'm really excited about your published results.

Thank you for raising this issue @cedwards77.
It should now be working, please let me know if you encounter further errors.
It was due to me refactoring chunks of the code and integrating multiple agents. I have now moved this code to my forked repository and will push once all testing, validating and training will be working.

Please note that you may receive a memory error if there is not enough RAM available, such as:

Thank you for your quick response @gml16 ! It seems to be working now.
