GRPC error

[errorer-max]

Hi @mrahtz , thanks for doing this repo! I think this algorithm is a milestone in the process of deep reinforcement learning. We installed all components according to the pipfile and pipfile.lock files, and a GRPC error occurred while training the predictor network after completing the collection of preferences. There was no problem with the first round of training, but an error was reported the second time.

Hardware resources: multi-core CPU, two GPUs 1080 TI

Running environment: Python 3.7 TensorFlow1.15

Pipenv operation： python3 run.py train_policy_with_preferences EnduroNoFrameskip-v4 --n_envs 16 --render_episodes --n_initial_prefers 10

Hmm, I'm sorry, I've never seen an error like that before, and I'm not sure what it means. It looks like it's coming from within TensorFlow, so my best guess is that's it's something to do with your TensorFlow, CUDA and cuDNN installations, or your GPU drivers. The only suggestion that comes to mind is to try installing NVIDIA's version of TensorFlow https://github.com/NVIDIA/tensorflow which seems to have better compatibility with newer GPU drivers.

Thank you very much for your suggestion. I have tried installing it https://github.com/NVIDIA/tensorflow/tree/r1.15.2 +Nv20.06, however, the result is still regrettable as the error still occurred. Before installing this version of TensorFlow, all CUDA versions on the server have been removed to avoid conflicts between CUDA versions.

Before running the algorithm, in order to complete all processes as soon as possible, I used 'python3 run. py train_policy_with references EnduroNoFrameskip-v4-- n_envs 16-- render_episodes -- n_initial_prefs 15'. Before running the algorithm, in order to complete all processes as soon as possible, I used 'python3 run. py train_policy_with references EnduroNoFrameskip-v4-- n_envs 16-- render_episodes -- n_initial_prefs 15'. That is to say, I only input preferences 15 times before starting to train the reward prediction network. I don't know if this setting will cause this problem to occur?

Hey, sorry for the slow reply - busy week.

If that didn't work, sorry, I'm out of ideas. I don't think it should make any difference which order you run the commands in - this really sounds like some weird error in TensorFlow itself. My impression is that TensorFlow 1.x is really pretty unsupported these days, so it might just be that it's too old.
