How to fix this?

[ccuetom]

Could you give us some more context? How are you running the script? How is your conda environment set up?

[elcolie]

Environment: Python 3.10.9 Linux bugger 6.4.0-4-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.4.13-1 (2023-08-31) x86_64 GNU/Linux Step to reproduce:

1. pip install .
2. jupyter notebook --ip 0.0.0.0 --no-browser --allow-root
3. Run 7th file by jupyter notebook

[ccuetom]

@elcolie have you installed stride using the conda environment?

[elcolie]

@ccuetom I am barely recall this issue now. I think I haven't installed stride.
