What I Did

i modify steganogan/models.py:

steganogan = torch.load(path, map_location='cpu', weights_only=False)

ERROR: Could not find a version that satisfies the requirement torch==1.8.1 (from versions: 2.2.0, 2.2.1, 2.2.2, 2.3.0, 2.3.1, 2.4.0, 2.4.1, 2.5.0, 2.5.1)

[notice] A new release of pip is available: 24.2 -> 24.3.1
[notice] To update, run: pip install --upgrade pip

   (1) Re-running torch.load with weights_only set to False will likely succeed, but it can result in arbitrary code execution. Do it only if you got the file from a trusted source.
   (2) Alternatively, to load with weights_only=True please check the recommended steps in the following error message.
   WeightsUnpickler error: Unsupported global: GLOBAL steganogan.models.SteganoGAN was not an allowed global by default. Please use torch.serialization.add_safe_globals([SteganoGAN]) to allowlist this global if you trust this class/function.

I don't know what else I can do. Model training works for me.

i ask gpt how to deal with it.
gpt told me to use docker
and i create a docker with python3.6 and encode successful.
now i cant decode

[kompowiec]

I also used chatgpt but they just suggested weights_only=False)

and i create a docker with python3.6 and encode successful.

now it's makes sense. I had no idea what version of python it required. As for torch, I'll probably have to manually download it from another source.
