I am getting this error when I try to run the pretrained hindsight-experience-replay

Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: “saved_models/‘FetchReach-v1’/model.pt”

The link of source is GitHub - TianhongDai/hindsight-experience-replay: This is the pytorch implementation of Hindsight Experience Replay (HER) - Experiment on all fetch robotic environments.

As the error message explains, it seems the specified file is not found and I guess you might have skipped this step, which asks you to download the files.

I have downloaded and saved it as mentioned but got the error.

In that case the additional characters around FetchReach-v1 might cause the issue or using a relative path from a wrong working directory.
