jupyter doesn't like metadata provided by ox-ipynb, prevents notebooks from loading

[vxe]

Get the below error when trying to open an exported notebook

Adding the metatdata section from a working notebook gets it to open

ox-ipynb

  "metadata": [
    [
      "org"
    ],
    null,
    null
  ],

working notebook

something did not work right on the export, the metadata from ox-ipynb is incomplete. can you post a MWE org file that does this? I am not able to reproduce it.

[vxe]

sure: metadata.org.tar.gz

additional org mode version: Org mode version 9.4.6 (9.4.6-10-gee652a-elpaplus

ox-ipynb does not work on Python cells. you should change them to ipython or jupyter-python cells.

Alternatively it might work to add this to your init

(setq ox-ipynb-kernelspecs 
      (append  ox-ipynb-kernelspecs '((python . (language_info . ((codemirror_mode . ((name . python)
                               (version . 3)))
                   (file_extension . ".py")
                   (mimetype . "text/x-python")
                   (name . "python")
                   (nbconvert_exporter . "python")
                   (pygments_lexer . "python3")
                   (version . "3.5.2")))))))

yeah works with ipython, cells

for future reference, i had to run this to get ipython blocks to evaluate

 pip3 install jupyter_console jupyter_client
