RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory

When I try running the program, I get the error:

/mnt/nfs/clustersw/Debian/bookworm/RFdiffusion/20240307/lib/python3.11/site-packages/rfdiffusion/util.py:253: UserWarning: Using torch.cross without specifying the dim arg is deprecated.
Please either pass the dim explicitly or simply use torch.linalg.cross.
The default value of dim will change to agree with that of linalg.cross in a future release. (Triggered internally at ../aten/src/ATen/native/Cross.cpp:63.)
Z = torch.cross(Xn, Yn)

RuntimeError: PytorchStreamReader failed reading zip archive: failed finding central directory

I have already redownloaded the models again but to no avail. I checked the path does exist. Can I have the checksums of the files or am I missing something?

Start with scripts-3.11/run_inference.py and rfdiffusion/inference/model_runners.py, especially load_checkpoint, where Base_ckpt.pt is passed to torch.load. Inspect the referenced model file and the model-download instructions or checksums, then reproduce the failure with the reported checkpoint path. Done means the checkpoint-integrity problem and a documented resolution are established.
