Here is the error:

I am not sure where the problem lies, during installation there were few problems related to numpy deprecated syntax, but nothing of serious note (i thought)

@Tomoki-YAMASHITA Thank you so much!

Following your inspection, I rewrote the SciPy dependence in the setup.py and requirements.txt. Now it passed the GitHub workflow https://github.com/qzhu2017/PyXtal/actions

We haven’t been able to pass the workflow since last December.
