TypeError: unhashable type: 'Str' when converting ipynb to html or pdf

[frezersa]

Bug Report

I was trying to export the example file (https://ipypublish.readthedocs.io/en/latest/_downloads/3aa8aebba17409bb5d3584eaa06bf0e2/Example.ipynb) into html or pdf using nbpublish following the procedure on https://ipypublish.readthedocs.io/en/latest/getting_started.html.

When running command [1]: nbpublish --log-level debug --print-traceback Example.ipynb

First issue: jinja2.exceptions.TemplateNotFound: display_priority.tplx
First fix: I changed the display_priority.tplx extension to display_priority.py following daha96@e3c9421

Second issue: when trying running command [1] after fixing the first issue, I got (full log error is at the end)
File "C:\Anaconda33\envs\ipyreport\lib\site-packages\ipypublish\filters_pandoc\prepare_labels.py", line 157, in
if el not in to_delete
TypeError: unhashable type: 'Str'

To Reproduce

Steps to reproduce the behavior:

1. changed the display_priority.tplx extension to display_priority.py

Minimal Notebook Example

I used the file https://ipypublish.readthedocs.io/en/latest/_downloads/3aa8aebba17409bb5d3584eaa06bf0e2/Example.ipynb

Expected Behaviour

Convert ipynb to html or preferably pdf with figure and table captions.
