I have manually installed melting pot and I have also changed rllib torch model file for the fix of LSTM wrapper . I am getting the assertion error while running training with these arguments .

Could you please run sh run_patches.sh in the root folder and let me know if this error still persists?
It looks like the patch I listed under tf is actually required for all cases.

Thanks.
