Original report by Alouette Zhang (Bitbucket: [Alouette Zhang](https://bitbucket.org/Alouette Zhang), ).

I encounter this error after installing moments==1.1.7 on Narval Compute Canada. I can't find which operating system Narval is using, my guess would be Linux CentOS 7. I loaded python 3.8.10, gsl, hdf5, prior to installation.

Here are the steps I took for installing, no issues:

git clone https://bitbucket.org/simongravel/moments.git
pip install --upgrade pip
pip install numpy, scipy, cython, mpmath, matplotlib, networkx, pandas

cd moments

python setup.py build_ext --inplace
python setup.py install --ld_extensions

Then I tried to import it after opening a python console, this error appears:
