installing fipy and pysparse with python3

[klkuhlm]

I had to update a system, and I was trying to re-install fipy (ubuntu 20.04) using conda. It seems pysparse is python 2.7 only (has this always been the case?) I am not able to install using the suggested command (which I thought had worked in the not-too-distant past).

$ conda create --name fipy --channel conda-forge python=3 numpy scipy matplotlib pysparse gmsh
It tries many different things, but fails in the end. After some attempts, it seems it is just pysparse that is causing the issues.

searching for pysparse available on conda-forge, I get the following

$ conda search pysparse --channel conda-forge
Loading channels: done
# Name                       Version           Build  Channel             
pysparse                     1.3.dev  py27h0c33204_4  conda-forge         
pysparse                     1.3.dev py27h3010b51_1001  conda-forge         
pysparse                     1.3.dev py27h3010b51_1002  conda-forge         
pysparse                     1.3.dev py27h3010b51_1003  conda-forge         
pysparse                     1.3.dev  py27h3010b51_5  conda-forge         
pysparse                     1.3.dev  py27h7eb728f_0  conda-forge         
pysparse                     1.3.dev  py27h7eb728f_1  conda-forge         
pysparse                     1.3.dev  py27h7eb728f_2  conda-forge         
pysparse                     1.3.dev  py27h8db774e_7  conda-forge         
pysparse                     1.3.dev  py27h970eebf_6  conda-forge       

Has something changed? Is there a different way to install fipy for python3 (leaving out pysparse?)

Sorry if I am missing something obvious.

Pysparse has only ever been available for Python 2.7.

On Ubuntu, you should be able to do

conda create --name <MYFIPYENV> --channel conda-forge python=3 fipy gmsh

If you want to install a develop version of FiPy (GitHub checkout for instance), then follow our instructions for setting up a development environment.

thank you. this works! thanks for the link to the instructions for the development version, too.
