I seem to not be able to run a  
`import matplotlib.pyplot as plt`  
on a hail dataproc. Numpy, scipy, and other packages are working, and matplotlib is installed on my computer. Is there somewhere on the vm that I can run a pip install matplotlib?

Thanks!

You can pass packages to install at cluster creation time with `--pkgs`, e.g. `--pkgs matplotlib`.

If you’re using a jupyter notebook running on an existing cluster, you can run shell commands in a jupyter cell:

```auto
! pip install matplotlib

```

I ran a  
`! pip install matplotlib`  
and got the error:  
`/bin/sh: 1: pip: not found `

I get the same error, that there is no module named pip. I also tried taking out the pip, after which the error was no module named install

I am currently restarting the cluster with the `--pkgs matplotlib` tag

Looking at our init scripts, it appears the Python installation running the notebook is `/opt/conda/default/bin/python`. So I think `/opt/conda/default/bin/python -m pip install matplotlib` should work

Restarting the cluster with the pkgs tag worked, thank you so much!
