Cannot Import riskparityportfolio in Jupyter Notebook or Lab: Undefined Symbol error

[Sp3ctro]

Problem description

Hi! I'm getting the following error when importing riskparityportfolio in Jupyter Notebooks or in Jupyter Lab.

ImportError: /home//riskparity.py/riskparityportfolio/vanilla.cpython-39-x86_64-linux-gnu.so: undefined symbol: _ZNSt15__exception_ptr13exception_ptr10_M_releaseEv

Example

import riskparityportfolio as rp

or

from riskparityportfolio import vanilla

...as was advised in another issue.

Expected behavior

I would expect riskparityportfolios to work in jupyter notebooks and in lab as it has done before. Oddly I have found in the past that if I make import riskparityportfolio as rp the first line in the notebook, it works. But this is no longer reliable (seems to no longer work). Using it in a script works fine.

Environment:

• platform (e.g. Linux, OSX, Windows): Ubuntu 21.10
• riskparityportfolio version (e.g. 1.1): riskparityportfolio 0.2
• Python: Conda Python 3.9
• installation method (e.g. pip, source): pip and the dev version via git clone (as advised in another issue)
• Jupyter versions:
• jupyter-client 7.0.6
• jupyter-core 4.8.1
• jupyter-server 1.11.2
• jupyterlab 3.2.1
• jupyterlab-pygments 0.1.2
• jupyterlab-server 2.8.2

Thanks in advance for taking a look!
