Installing powerfit in a Centos 8 machine

[clacri]

Hi, I am trying to install powerfit into a new centos 8 machine, and after running successfully the install script within a conda environment that I specifically created for this purpose, when trying to execute powerfit, I get the following error:

ImportError: /my/home/anaconda3/envs/emlearning/lib/python3.6/site-packages/powerfit-2.0.0-py3.6-linux-x86_64.egg/powerfit/_extensions.cpython-36m-x86_64-linux-gnu.so: undefined symbol: Py_InitModule

the conda list command is as follows

It seems it can be a Python 2 / 3 issue related problem, but I am not sure on how to proceed, so I am hoping you can have some useful advice. Please let me know if there is any extra information you need.

Python 2/3 issue indeed. Check the requirements on https://github.com/haddocking/powerfit So create a python2.7 environment with conda and then install it
