Estimating Number of Jupyter Notebooks on Github

I've noticed that if I dont install jupyter to each venv, then the pythonpath defaults to the jupyter install. As a result, the jupyter notebook cannot find the packages in the venv(for example, caffe, module not found errors)

huh, I've never used Caffe but wrapping my venvs with pipenv has never caused me this kind of grief.

I tell pipenv to store venv stuff in the project folder (`export PIPENV_VENV_IN_PROJECT=1`), and then do the following to start a new project:

    pipenv --python 3.7
    pipenv install ipykernel
    pipenv run python -m ipykernel install --user --name=`basename $(pipenv run dirname '$VIRTUAL_ENV')
    jupyter lab

(all the magic is in that third command)

Then in the list of kernels, in addition to the usual suspects I'll have one named for the folder I ran the above in. If I started a notebook before all that, I'll have to change it's kernel. Doing more `pipenv install` at the prompt makes new packages immediately available in the running notebook.
