Installation issue via pip

Hello, I was trying to install Netgen via pip.

But, I had an error message like below

What should I do to fix this error?


You seem to have installed TBB with another package manager, likely system one. Either fix this, for example like explained here or install ngsolve in a fresh venv.

I made a virtual environment in Anaconda.

But, still I have the issue like below.

I used
“conda install ngsolve” or “conda install -c ngsolve ngsolve” command for the installation.

Either did not work.

Also, I tried to install NGSolve in different python version (3.10). But, still it didn’t work.

Try installing ngsolve with pip in the virtual environment. I think the conda installers are not up to date.
