I was recently told ( file:///C:/Users/BrenBarn/AppData/Roaming/jupyter/runtime/nbserver-6156-open.html ) that Jupyterlab is supposed to be ready for prime time. For me that would include interactive use of Matplotlib. Apparently the way to do this in Jupyterlab is with ipympl, aka "jupyter-matplotlib" at https://github.com/matplotlib/jupyter-matplotlib .
Looking at the instructions, I see it tells me to install from conda-forge. However, I have found several warnings (e.g., here https://github.com/conda/conda/issues/8920#issuecomment-519105949 ) that mixing conda defaults and conda-forge channels can cause problems. I have experienced this myself with conda going crazy upgrading and downgrading packages due to slight version differences between the packages in different channels.
I am going to be teaching a class using Python. I do not want to use conda-forge because I want to keep installation of everything as simple as possible for the students and avoid the possibility of such problems.
So my question is: is it possible to get fully functional interactive Matplotlib in Jupyterlab WITHOUT ever using conda-forge? If not, I would say that Jupyterlab is not really ready for primetime! (I realize that, if the answer is no, that may be more an Anaconda issue than a Matplotlib or Jupyter issue, but I'm just trying to figure out whether it's actually possible to replicate my working Jupyter notebook environment in Jupyterlab using only the conda defaults channel.)
Thanks,
