DDQN model submission failed

Hi @Paseul

I’m sorry to hear that your submission did not work. Using pytorch-cpu should work. I made my submission this way. I propose the following steps to resolve the issues:

  1. If you are running on a CPU-only machine, please use torch.load with map_location='cpu' to map your storages to the CPU`
  2. if this does not work. Uninstall pytorch in your conda environment. Then run the following command in your conda env conda install -c pytorch pytorch-cpu. Once this is done you have to update your environment.yml as explained in the starter kit.

Please let me know if this resolves your issues.

Best regards
Erik
