issue with petsc4py

JAX itself is not meant to be used on Windows. Same holds true for JAX-FEM. Please consider a linux system like Ubuntu or Mac OS will also be fine.

"ModuleNotFoundError: No module named 'petsc4py'
I am also unable to install petsc4py via pip.
Can you give a solution?"

[tianjuxue]

Please exactly follow the instruction to install JAX-FEM. petsc4py is known to have issue with pip. You can only use conda to install petsc4py.

Are you using Windows? If so, please avoid using Windows. There is no support for Windows for JAX-FEM.
