================

Python bindings for PETSc.

Install
-------

If you have a working MPI implementation and the ``mpicc`` compiler
wrapper is on your search path, it highly recommended to install
``mpi4py`` first::

  $ pip install mpi4py

Ensure you have NumPy installed::

  $ pip install numpy

and finally::

  $ pip install petsc petsc4py

You can also install the in-development version of petsc4py with::

  $ pip install Cython numpy mpi4py
  $ pip install --no-deps git+https://gitlab.com/petsc/petsc
  $ pip install --no-deps git+https://gitlab.com/petsc/petsc4py

or::

  $ pip install Cython numpy mpi4py
  $ pip install --no-deps https://gitlab.com/petsc/petsc/-/archive/master.tar.gz
  $ pip install --no-deps https://gitlab.com/petsc/petsc4py/-/archive/master.tar.gz
