[Bug?] `RuntimeError: File size unexpectedly exceeded ZIP64 limit` and switching from np.save to np.savez
See original GitHub issueSo I’m using python 3.7, numpy 1.19.5 (the latest version of numpy that supports 3.7). I was training with roughly 4GB MLP models and automatically save them after training, and the runs crashed with RuntimeError: File size unexpectedly exceeded ZIP64 limit. Upon Googling this error, this is just something that happens in NumPy with matrices larger than 2GB (see https://github.com/numpy/numpy/issues/13153), which is a reasonable thing to support in SB3. While this sure feels like something numpy should fix after looking into the mechanisms of the bug, the official numpy maintainer recommendation was to switch from .save to .savez, and I’m aware of no new changes to this.

Quite likely the same issue. Try installing stable-baselines3 from the repository with
pip3 install git+https://github.com/DLR-RM/stable-baselines3(the change is not on pip yet, I think).Worked! Thanks
