• That bug only occurs when you try to plot, correct?
• You can try either:
  • Moving conda install -y -c conda-forge pycalphad to the end of Dockerfile
  • Moving pycalphad from conda (see above) to pip installation in the Dockerfile

[amr8004]

This error occurs when you try to import pycalphad or anything wherein in the jupyter notebook

Appears fixed now!
