[petsc-users] PETSc for python

[Лев Усов]

Hello, dear colleagues!

I'm trying to download the PETSc library for python. I use the pip command:
"pip install mpi4py petsc petsc4py" for python3 on Windows11, but I get an
installation error (see attached file).
Could you help me with this?

Best regards,
Lev.
