@SaaSGun Hi, the medcoupling PyPI package is now maintained by @jschueller. Maybe he can lend a hand?

SaaSGun commented 3 months ago

@tianyikillua - thankyou for your response. Waiting to hear from @jschueller!

So basically, taking following steps helped solve my issue -

started with a clean conda virtual environment ran the following: conda install conda-forge::meshio conda install conda-forge::medcoupling pip install --no-deps pymapping (make sure pymapping does get installed in the virtual env and not in the base environment)

make sure you're not mixing packages from conda-forge and defaults (use miniforge) anyway its not related to our pypi packages
