'jupyter kernelspec list' fails with syntax error #464

Closed twirlywoo closed 5 years ago

twirlywoo commented 5 years ago

Hi all, wondering if someone has come across this issue before and might have a solution? I have two problems, which might be linked:

  1. after deleting a conda environment and creating a new one, I now get dead kernels when I try to run 'jupyter notebook' from the anaconda prompt. The browser opens fine, but the kernel won't connect.
  2. when I try to debug problem 1 by typing jupyter kernelspec list in my anaconda prompt, I get a syntax error as follows:

It looks like the problem is in line 4 of kernelspec-script.py: "from jupyter_client.kernelspecapp import KernelSpecApp.launch_instance". Am I doing something wrong?

I'm working in Windows 7 Professional Anaconda 5.0.1 python 3.7.0 jupyter-client 5.2.3 ipykernel 5.1.0

Really grateful if anyone has a fix for this. Thank you!

I got the kernel working again by doing this: python -m ipykernel install --user --name myenv --display-name "Python (myenv)" As in jupyter issue #245.

"jupyter kernelspec list" is still giving the syntax error though. So issue 1 is solved but issue 2 still there :-)

What is conda list? I think this might be a problem with either conda or the conda package for jupyter_client.

I suspect this might be a problem in the conda client that may be fixed in a recent version. Can you try:

conda update conda

and then remove and reinstall the jupyter_client package?

twirlywoo commented 5 years ago

I tried conda update conda at the Anaconda prompt, but got this error:

image

Erm. I'm not sure what that error means! Should I try conda update --all ?

twirlywoo commented 5 years ago

@minrk thanks for your help. I remembered that I don't have admin rights on my machine to update my version of Anaconda. Could that be part of the issue?

minrk commented 5 years ago

That's possible. I'm guessing that this is a bug in older versions of conda not properly supporting entrypoints in noarch: python packages. Updating conda itself to 4.5.x would likely solve the problem.

twirlywoo commented 5 years ago

Closing issue as I think I have the answer. I just won't be able to implement it yet :-) Thank you @minrk.
