Error when installing mpi4py

Question

I\'m trying to install mpi4py using pip install mpi4py, but I\'m getting the following error:

error: Cannot find \'mpi.h\' header. Check your configuration!!!
<         


        

Answer 1

As the error says, there are libraries missing. I solved it by installing libopenmpi-dev package

sudo apt install libopenmpi-dev

and then installed the mpi4py using pip

sudo pip install mpi4py
