Install Salome Failed with error "No module named '_omnipy'"

Question

I've trying to install SALOME-9.8 on ubuntu 20.04. After the download and extraction, I ran the script salome. But i get the following error:

ERROR:salomeContext:Unexpected error:
Traceback (most recent call last):

I've also installed anaconda on my pc. I'm not sure if it is related with it.

Answer 1

After that, I've tried to download the image from here. But it seems that the container Singularity doesn't work so well on my computer. I can only run the software in CPU mode. And when I was doing something related to the mesh, it would be very slow.

Finally, I installed the salome-meca according to this video. After deal with some small problem with the help of the instructions in the video page, the salome works pretty well.
