My notebook doesn't connect to the kernel

Hello everyone,

I have been stuck on this issue for a while now. I have been trying to use jupyter on my virtual desktop, but my notebook is not capable to connect to the kernel. I have been looking around, and I believe that it probably has to do with server configurations, etc. which are out of my control and under the administrators of the virtual desktop control.

Anyway, here’s the information I can share with you.

What happens when I launch jupyter notebook --debug :

I have the following kernel specifications. I have removed my python path to use instead the ipykernel package, as a thought this might help :

(temperature) C:\Users\jewell>jupyter kernelspec list
Available kernels:
  python3    C:\Users\jewell\Miniconda3\envs\temperature\lib\site-packages\ipykernel\resources

EDIT

I have a functioning environment when I clone the base environment from Anaconda. Jupyter then works. However, when I try to create a new environment and load only jupyter (and its dependencies), the same problem arises.

  • Problematic environment Web console

  • Functioning environment terminal output when launching jupyter (funnily calls jupyter lab --> important?)

    To access the notebook, open this file in a browser:
        file:///C:/Users/jewell/AppData/Roaming/jupyter/runtime/nbserver-9752-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=37941e3942674c5d27c61f15cf2a796f173cc8d1e06a3643

Can you bring up your browser’s developer console and see if there are any warnings/errors when you try and run a notebook?

@manics I have added what you asked. Just in case, here is the list of packages I have in the cloned environment.

  • Functioning environment package list (clone from Anaconda base environment). Because it is a clone, there are many packages that I don’t need ^^

One thing that stands out is you’ve got a very old version of notebook, 4.4.1, in your temperature conda environment. Could you try upgrading it?

@manics Thank you very much! This was the solution indeed :slight_smile: I tried unsuccessfully conda update notebook, but then I tried conda install notebook=6 which worked out. Again, thank you very much :slight_smile:

It seems that after eight months this issue is still alive.

In my case, I created a new virtual environment but I did not want to install Jupyter notebook again via conda install -c conda-forge notebook, so when I opened the notebook did not work in this environment.

After reading this discussion I used conda install notebook=6.1.4, which was the version used in another virtual environment that I have, and it worked!.

However, I was wondering if every single virtual environment needs this installation.
I found some discussions about this but nothing concrete, or it did not work for me in the same way that for others.

Anyways, thank you guys for starting this discussion.
