No text on open notebook

[ando600]

Hi, I have vimpyter installed on both vim and nvim, and I have notedown version 1.5.1 installed. However, when I open a jupyter notebook, I see nothing in the vim terminal, and zc /zo doesnt find any closed folds. Below is a screenshot of the jupyter notebook and my vim teriminal. Do I need to configure the notedown in some way?
Thanks,

Andrew

Same here. Haven't tried to do any major debugging but my installation seems correct.

E:

Using VIM 8.2 on Pop!_OS 20.10 and notedown 1.5.1

I have the same issue with both Vim 8.2.2029 and NeoVim 0.4.4.

Vim 8.2 and Notedown 1.5.1 on macOS, same issue... Pretty sure this isn't an authoritative solution as it feels super kludgey, but it worked for me 🤷‍♀️

I tried running notedown standalone and it barfed an error that ended like this:

$ notedown --from notebook --to markdown -o test.md test.ipynb
...
  File "/opt/miniconda3/share/jupyter/nbconvert/templates/compatibility/display_priority.tpl", line 2, in top-level template code
    {%- extends 'display_priority.j2' -%}
jinja2.exceptions.TemplateNotFound: ../base/display_priority.j2

This also resulted in an empty test.md file. So I went to /opt/miniconda3/share/jupyter/nbconvert/templates/compatibility/display_priority.tpl, which looked like this:

{{ resources.deprecated("This template is deprecated, please use base/display_priority.j2") }}
{%- extends 'display_priority.j2' -%}

And I changed the path in the extends to include the base dir, viz.:

...
{%- extends 'base/display_priority.j2' -%}

And now I can vim into test.ipynb – it works fine and looks beautiful.

@p-sgarbi Thank you that worked, though this looks like an issue with nbconvert?

For anyone else who comes across this issue the notedown problem is mentioned in aaren/notedown#95. Since the breaking change comes from nbconvert v6, another easy way to fix this is to downgrade your installation of nbconvert after you have installed notedown:

pip install nbconvert==5.*

After this you should find that notedown works properly and vimpyter will be able to convert notebooks to markdown to display in the terminal.
