Notebook: LaTeX rendering pipe ("|") character after each LaTeX expression

[marwahaha]

I think this is a bug ---every LaTeX expression written within a Markdown cell will append a "pipe" character (or maybe it's a vertical line?). I think this is new, and maybe something to do with MathJax and Jupyter interacting..

This happens locally, and on renderings with Github.

Here's an example ("Let's choose n=2")

Duplicate of #1053 and #1010 , fixed by #1032 (bug in chrome).

This is still an issue for me on Chrome. I have updated the Jupyter Notebook and the pipe still appears after the expression. What is the fix?

[takluyver]

The fix should be in the latest version of the notebook (4.2.0). If you've just updated, you may be having browser caching issues - hit Ctrl-F5 a few times to force refresh.

@takluyver confirm that doing pip install --upgrade notebook solved the problem for me, thank you ^__^

I'm still seeing this issue.

Running Python 3.5.1 (Anaconda 4.0.0 (64-bit)) and Chromium 50.0.2661.102 built on Ubuntu 14.04, running on LinuxMint 17.2 (64-bit)

Running pip install --upgrade jupyter produces:

Requirement already up-to-date: jupyter in /opt/continuum/anaconda3/lib/python3.5/site-packages

Jupyter version is 4.1.0

Did you pip install --upgrade notebook, or just jupyter. updating the notebook fixed it for me

[cstoudt]

Yes, that did the trick, thanks!

I was under the impression that notebook was deprecated and that jupyter
was the replacement.

Apparently, I don't understand the relationship between jupyter and
notebook.

Jupyter is a meta pacakge.
jupyter does nothing by itself it just install the following:

        'notebook',
        'qtconsole',
        'jupyter-console',
        'nbconvert',
        'ipykernel',
        'ipywidgets',

Each of these may depend on jupyter_client, nbformat, etc....
It is perfectly reasonable to only want a subset of these – if you are interested in subpart of functionality of have a lightweight computer like a raspberry Pi –  and yes we agree that pip install jupyter --upgrade should update notebook, and is confusing though it is not how pip works.

Sorry --- is this still a bug for Github rendering?

Not any more,
This was fixed by an update to the notebook. If you’re still encountering it, update your jupyter-notebook

Hi, this bug is still present for me. I am on Chrome 52 and notebook 4.2.2.

Every jupyter notebook I see on Chrome with latex in it has this issue. Could I get help?

[jarmarshall]

Ditto, but on Mac (Sierra) in Safari. I updated the notebook via pip as per above, then restarted my terminal, and Safari. Still the same problem.

[bearsnowstorm]

Hi @jarmarshall - I had the same problem with new everything (chrome / safari / notebook) on El Capitan - _clearing the cache_ on Chrome and Safari ultimately fixed it for me - your mileage may vary

[jarmarshall]

Thanks @bearsnowstorm - tried that (via 'Develop -> Empty Cache'). Then restarted the Jupyter notebook server. Still no joy. Maybe I should try running the server via Firefox or ...

[jarmarshall]

OK, Firefox renders the LaTeX correctly (no bar). I'm guessing this bug is not fully resolved in Safari given the various steps I've taken.

[lazarillo]

Just stumbled across this. FWIW, clearing the cache and refreshing the browser (in Chrome) also cleared the problem for me.
