PDF conversion #1552

Open RalfKellner opened 3 years ago

RalfKellner commented 3 years ago

Hey everyone,

I know this question already popped up in the past, but the recommendations and answers in past posts do not really help in my case. Until today, I had no problems converting my Slides to html and save them as pdf. However, today I get a warning which does not harm the html, but makes it impossible to save as pdf properly.

The warning is as follows: NbConvertApp] Converting notebook 02_MDPs_value_functions.ipynb to slides [NbConvertApp] Writing 331840 bytes to 02_MDPs_value_functions.slides.html [NbConvertApp] Redirecting reveal.js requests to https://cdnjs.cloudflare.com/ajax/libs/reveal.js/3.5.0 Serving your slides at http://127.0.0.1:8000/02_MDPs_value_functions.slides.html Use Control-C to stop this server WARNING:tornado.access:404 GET /custom.css (127.0.0.1) 0.60ms WARNING:tornado.access:404 GET /custom.css (127.0.0.1) 0.53ms WARNING:tornado.access:404 GET /custom.css (127.0.0.1) 0.53ms WARNING:tornado.access:404 GET /custom.css (127.0.0.1) 0.50ms

As I have no clue about js and css, could you try to help me in a dummy way;)

Many thanks in advance! Ralf

I really would appreciate any help, I tried it on another system and with another browser, the problem stays the same...

@RalfKellner can you report the following, assuming you're using pip?

pip show nbconvert

Additionally, could you share a small notebook that reproduces the issue so that we can compare results?

RalfKellner commented 3 years ago

@agoose77 sure thing: pip show nbconvert output is as follows:

Name: nbconvert Version: 5.6.1 Summary: Converting Jupyter Notebooks Home-page: https://jupyter.org Author: Jupyter Development Team Author-email: jupyter@googlegroups.com License: BSD Location: /Users/ralfkellner/opt/anaconda3/lib/python3.8/site-packages Requires: pandocfilters, nbformat, pygments, mistune, defusedxml, traitlets, entrypoints, testpath, jupyter-core, bleach, jinja2 Required-by: spyder, notebook, myst-nb, jupyter, jupyter-sphinx, jupyter-latex-envs, jupyter-contrib-nbextensions, jupyter-book, hide-code

and a short example which leads to the warning is here:

https://github.com/RalfKellner/github-slideshow/blob/main/slideshow.ipynb

What I do to convert is: jupyter nbconvert --to slides slideshow.ipynb --post serve

and just to clarify it: The cells are Slides using the RISE extension

How do you save them to PDF once you've generated the slides? As an aside, the newer version of nbconvert doesn't have this warning.

RalfKellner commented 3 years ago

Alright, I currently installed the new version and it works. Now I only get the error when saving it as pdf.

I do so as explained here: https://rise.readthedocs.io/en/stable/exportpdf.html

So by adding the ?pdf-print ending.

When I do this the warning appears once more. Nevertheless, it works, however, the format is a little messed up.

By the way I tried the current version of nbconvert yesterday and conversion failed due to template errors...

agoose77 commented 3 years ago

Could you share a screenshot? It seems to work fine for me. What browser do you use?

The first file is how it looks now, the second file is how it looked when it was working fine. I am using Firefox and I also tried it with Chrome. Behavior was the same.
