could not import matplotlib

[hhy2022]

Hi, I am a new user of MOOSE. I was trying to use peacock to run the input because I would like to see the visualized result. My command was the one provide in the slides of 2022. '~/projects/moose/python/peacock/peacock -i step1.i'
However, when I use this command, I got a message saying that--
'Error starting peacock: Could not import matplotlib
'You need to use the miniconda module. Run:
'module load miniconda'
I tried to run 'module load miniconda' and it said command not found.
I guess there might be something wrong with my peacock but I don't know how to fix it.
Besides, I use Ubuntu.
Thank you very much for any help.

Hello

You are using Ubuntu on your local machine?
Did you activate the conda (mamba) environement?
Can you install matplotlib with mamba install matplotlib ?

Yes. I am using Ubuntu on local machine. I had activated conda.
I install matplotlib successfully, and I can call peakcock successfully.
Thank you so much for your help.

I think there s a libmesh-vtk package you can download. @milljm suggested creating another environment just for peacock and listed the packages. It s in another post if you care to search (getting late for me)
