ImportError on jupyter notebook

[Jinyin-Hu]

Hello,

After updating the latest version of mtuq, I ran into this import error on my jupyter notebook (jupyter notebook --version: 6.5.4; Python 3.8.18). Interestingly, it is working well on the termial. Many thanks in advance.

from mtuq import Station, Origin, MomentTensor

just for an update, I downgraded my jupyter notebook to 6.0.0. then it works. Yeah!

thanks for the update, glad that it works

in case the problem recurs, rebuilding the C extensions by running the following script can also sometimes help? build_ext.sh
