Error when trying to access Jupyter conda API to retrieve information about two default environments for kernel specifications

After installing conda (python 3.5, channel= conda-forge) and numerous packages using conda and jupyter labextension...

When I check 

conda info --envs

only the root environment is listed even though I haven't created any additional environments)

https://i.stack.imgur.com/eWPrP.png

As a result, some unusual issues have cropped up:

  1. An error occurred while retrieving installed packages.

    EnvironmentLocationNotFound: Not a conda environment: /opt/conda/envs/conda

Additionally, there are two default environments in jupyter conda

  1. I encounter an error when trying to launch jupyter (notebook or lab): 

    [E 16:33:06.973 LabApp] Uncaught exception GET /api/kernelspecs?1525530786969 (172.17.0.1)

[E 16:35:44.455 LabApp] 500 GET /api/kernelspecs (172.17.0.1) 3.71ms

    Consequently, despite being listed in 

    jupyter kernelspec list

One solution could be to utilize pip 9.x and 

pip install --upgrade jupyter-client

However, my preference is to resolve it within conda.

Answer №1

If you prefer updating through conda instead of pip, you can use the following command:

conda update jupyter_client jupyter_core

Answer №2

Encountering the identical issue, I managed to resolve it by executing the following command in WSL Ubuntu:

sudo apt install jupyter-core

It appears that pip alone does not meet all Linux prerequisites.
