Seeking for help on basic test

image
Hi, I just installed devsim on Centos7, under the user menu since I don’t have the permission to root menu in this server. And during the basic test, I’ve been seeing these two problem all the time. I check the path for devsim installation which is correct… Did anybody meet this kind of problem before?

did you install using pip using a virtual environment?

python3 -mvenv venv
source venv/bin/activate
pip install devsim
cd $VIRTUAL_ENV/devsim_data/testing 
python mos_2d.py
