ValueError: mutable default <class 'timm.models.maxxvit.MaxxVitConvCfg'> for field conv_cfg is not allowed: use default_factory

I follow the previous steps

git clone https://github.com/chengtan9907/OpenSTL
cd OpenSTL
conda env create -f environment.yml
conda activate OpenSTL
python setup.py develop
bash tools/prepare_data/download_mmnist.sh
python tools/train.py -d mmnist --lr 1e-3 -c configs/mmnist/simvp/SimVP_gSTA.py --ex_name mmnist_simvp_gsta

And the bug comes up

ValueError: mutable default <class 'timm.models.maxxvit.MaxxVitConvCfg'> for field conv_cfg is not allowed: use default_factory

I tried to fix it and I found this in StackOverflow.

It seems it's a bug caused by Python version 3.11. And I checked your environment.yml and install.md, you suggest Python 3.7+ .
But following the environment.yml, the latest Python version will be installed and the bug will arise.

I suggest you change python to python==3.x((eg, 3.9, which I check is OK) in environment.yml.

In case others meet this bug. Thank you!

Thanks a lot, I encountered the same issue too! Since there are so many dependence, it seems like I can't simply downgrade the python, but only reinstall the environment, which wastes a lot of time😢

Hi, I have tried to install environments with Python>=3.11.x and the same error occurred. But Python==3.10.x can work. Maybe a better choice is to create a new conda env and reinstall the environments by python setup.py develop.

conda create -n openstl python=3.10
pip install torch==1.12.1+cu116 torchvision==0.13.1+cu116 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu116
conda activate openstl
python setup.py develop

If you want to stay on the later (unsupported) versions still, here is a fix for the issue:
huggingface/pytorch-image-models#1530 (comment)

Also include 'field' in the "from dataclass import ..." statement at the top of the python file located at 'kohya_ss-22.1.0\venv\Lib\site-packages\timm\models\maxxvit.py'
