Unit tests fail with mpich

Please try with the command:

mpirun -np 1 --host localhost:16 python -m mpi4py examples/plot_gait.py

My guess is that you are trying to run the notebook without mpirun -np 1.. part of the command. It is possible with openmpi but not mpich. I hope this helps.

I am getting this when running examples/plot_gait.py:

[DEBUG:DICODILE] Lambda_max = 1.7133212673372127
[mpiexec@mendoza-PC] match_arg (utils/args/args.c:160): unrecognized argument pmi_args

with mpich-3.4.2, mpi4py-3.1.1, and mpi-1.0-mpich.

Hi @chmendoza

What is the command that you are using to run the example?

[chmendoza]

I don't have my laptop with me right now to recreate this and give more detail, but it was python plot_gait.py. I could post here more details about the conda environment if you think is needed.

That worked @hndgzkn, thanks! Although I am using this package in my conda environment:

openmpi 4.1.1 hbfc84c5_0

so, I am not using mpich

Finally, I ran the tests, with $ pytest ., and 35 tests passed, with 10 warnings.
