It is common that the different projects you are working on depend on different versions of Python. That is why pyenv becomes very handy for Python developer...

Hi Albert. Very useful post and great workflow to work with python. A couple of question:

1. I understand from your post that its not necessary to install in each environment ipython/jupyter using pip. In case of required jupyter its just enough to create a kernel and associated the environment, then using just a "general" jupyter?

2. Do you recommend install jupyterlab from brew?

3. Exist a way some way to create automatically the kernel.json file when you created an environment with pyenv virtualenv? I mean something that emulate ipython kernel install --user --name=<name>

best, Cristóbal

@alcazar90 Thanks for your comment! To answer your questions:

1. Yes, I think it is easier to create kernels instead of installing jupyter in each different virtual environment.
2. I don't think it is necessary to install jupyterlab from brew, I haven't tried it, and I haven't really encountered any problem using pip to install jupyterlab so far.
3. I tried but the kernel.json file just wasn't updated automatically, that's why in the post I suggested editing the file manually. If you know of some ways to automate that, please share! Thank you again!

@albertauyeung I installed jupyter globally in one of the python versions using pip, but I have problems running virtualenv as kernels following your instructions at least if I previously installed ipykernel in each of the environment I want to used it.

Im searching a way to automate the kernel creation...any advance with this I comment here! best,
