I am trying to have execute Cartoon-StyleGan2 on my Mac OS, but it shows the error when I start the code. I have tried few ways like downgrading my python version, executing in python environment, as well as checking my env have torch installed properly, but still unable to run the code properly. Is it because the torch version is incompatible to the original project which was 1.8.0?

Tried Solutions:

• Tried to downgrade python to 3.8.0 because the project seems to be tested in PyTorch 1.8.0, CUDA 11.1. can't downgrade anymore because python 3.8.0 is deprecated.
• Reinstalled torch through official site under OS with

pip3 install torch torchvision

• I use pip list and PyTorch already did show in my list, it is shown as torch 2.6.0
• use pip install torch==1.8.0 torchvision==0.9.0 torchaudio==0.8.0 on version 3.9.3 ERROR: Could not find a version that satisfies the requirement

torch==1.8.0 (from versions: 1.9.0, 1.10.0, 1.10.1, 1.10.2, 1.11.0, 1.12.0, 1.12.1, 1.13.0, 1.13.1, 2.0.0, 2.0.1, 2.1.0, 2.1.1, 2.1.2, 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, 2.6.0)

• When use python to execute it works

import torch
print(torch.__version__) -- Shows 2.6.0

• Using uv python environment to setup

• What is your current environment's status? Is it a python virtual environment or a conda environment? If NOT a conda environment, can you do: pip freeze > requirements.txt and post the result? cat requirements.txt? (the last command is assuming you are on Linux. If you are in windows, just post the content of requirements.txt). – Gwang-Jin Kim Commented yesterday
• And what is your current python version? – Gwang-Jin Kim Commented yesterday
• Hi currently I am using python virtual environment, tried on python 3.9.3 and python 3.13.2 (latest version), and I am running on mac – Chuah Sze Wei Commented 16 hours ago

I totally fot to check for what. You want to simply follow some older tutorial about style GAN.

You don't need to follow that so literally! Of course such a task will be totally possible with the newest versions of torch and the rest of the packages.

-- ah I see - the checkpoint files - they might be not compatible with too new versions ... we don't know - only trying will give the answer.

Or - I would recommend to search for a newer tutorial then ...

Simply use the newest packages. Use this script:

#!/usr/bin/env bash

set -e  # Stop on error

echo "
