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):

    import _omnipy
ModuleNotFoundError: No module named '_omnipy'

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

  • Could you please share more details about how you got to this point? Are you in a virtual environment? What commands did you run and in which order? – Paul P Mar 30 '22 at 13:49
  • I am not working on a virtual machin. I just download the salome from the official website. And I ran the command `${ROOT}/sat config SALOME-9.8.0-native --check_system`, to check out if i have installed the required package. And I followed the instruction to install the required the package. After all, I ran the script `salome`. I got this error. – CHEN Duanwu Mar 31 '22 at 01:10

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.

I ran into the same issue. What worked for me:

Deactivate the conda base environment
conda deactivate

Create a symlink to phyton
sudo apt install python-is-python3

Run salome
./salome

More info about symlink here
