Same issue for me: TypeError: 'str' object is not callable

I also ran pip3 install nbconvert and pip3 install mistune to update those to the current version, but still the same issue.

The demos look very cool!

To me, this seems like a it would be a great app to package with Docker.

If there's an more reliable / easier route than Docker, that's a great idea too, because often times doing presentations you'll have to use a venue provided computer, and those systems usually only have:

1. Ancient Browser
2. PDF Reader
3. PowerPoint
4. Maximally unreliable Wifi...

Fortunately, they'll usually let you install whatever you want.

• Python 3.10.4
• mistune 2.0.4
• nbconvert 7.0.0

check if you have same versions with pip show {package_name}

Thank you. The problem for me was nbconvert was at 6.5.3.
Once upgrading nbconvert to 7.0.0, present is working fine for me.

❯ python --version 
Python 3.10.6

❯ pip3 show mistune | grep '^Version'
Version: 2.0.4

❯ pip3 show nbconvert | grep '^Version'
Version: 6.5.3

pip3 install --upgrade nbconvert

Now I'm at:

❯ pip3 show nbconvert | grep '^Version'
Version: 7.0.0
