Jupyter isn't showing all enviroments #60

Hi, I'm having this annoying problem.

If I list all the current environments I get:

alejandroalvarez@PMITN010321:~$ conda info --envs
# conda environments:
#
imgqlty                  /home/alejandroalvarez/anaconda3/envs/imgqlty
opencv                   /home/alejandroalvarez/anaconda3/envs/opencv
root                  *  /home/alejandroalvarez/anaconda3

But then, after launching jupyter, it doesn't show the opencv environment!

alejandroalvarez@PMITN010321:~$ jupyter notebook

Can you give me a hand with this?

I believe the issue is that the opencv environment needs to also have some the ipykernel Jupyter package. Also, this issue should probably be in this issue tracker:

https://github.com/Anaconda-Platform/nb_conda_kernels/

nb_conda gives you some control of conda environments and conda packages from inside Jupyter, whereas nb_conda_kernels is the thing that actually creates the list you've shown in your screenshot above. The GH README.md file for nb_conda_kernels provides some more details. I'm going to close this, but open it again if you think the problem persists after you've done:

conda install -n opencv ipykernel

Thank you! Now it's solved.
