Notebook tab not showing anything #388

Closed sancho-s closed 1 year ago

sancho-s commented 1 year ago

Description of your problem

What steps will reproduce the problem?

  1. Install python3, virtualenv, python3-pip, python3-dev via apt, see my packages below, only a few are listed. This is a minor departure from this, no upgrade of pip, and virtualenv installed via apt instead of pip3.
  2. Create a virtualenv
  3. Install spyder + jupyter via pip
  4. Launch spyder, see below
  5. Switch to tab Notebook
  6. Open an existing notebook, or create a new one

For item 1 above

Hey @sancho-s, thanks for reporting. I think the notebook should be displayed correctly if you go to this

http://localhost:8888/?token=173564737e999d60998a362def73788fab59e6c93fe6e3f8

or this

http://127.0.0.1:8888/?token=173564737e999d60998a362def73788fab59e6c93fe6e3f8

address, but I'm not really sure.

ccordoba12 commented 1 year ago

I'm going to close this issue as a duplicate of #386 because they are basically the same. As I said there, at the moment we don't know why it happens, sorry.
