I did conda install jinja2 and now I got a different error with xelatex:

Also ran into this issue with nbconvert==6.1.0. Strange as I've been using the same script for months now without any problem, with all dependencies fixed to the specific versions. Is it possible that this older version of nbconvert got some kind of bug retroactively?

EDIT: a workaround for me was to upgrade to the latest version (pip install nbconvert==6.4.3). I guess it's not ideal, but hey... works for now.

Jinja2 3.1.1

as the title suggests, jinja 3.1.x, one of the key upstreams of nbconvert, has deprecated a number of APIs. You might be able to pin to jinja<3.1 if you are relying on some bug/feature, but #1737 and subsequent have been released, restoring this compatibility.

we'll be trying to ensure better coverage of this in the future, and stay as compatible as possible, but as a tool and a library relied upon by other packages, it's rather hard for us to just blanket pin dependency versions, see #1740.

nbconvert==6.1.0

As has been suggested in a number of places related to this, if you start hard pinning individual values of dependencies, you likely need to pin, and check in, a complete solution to your environment, including all transient dependencies, and critically evaluate when you are forced to re-solve, e.g. because of security concerns.

A number of tools make this more tractable, such as:

• pip-tools
• conda-lock

[proinsias]

Still seeing this issue with nbconvert 6.5.0. Had to pin jinja2<3.1.

[scchess]

pip install nbconvert==6.4.3 worked for me.

[lneuhaus]

pip install nbconvert --upgrade solved this for me (installing version 7.2.9). I think the issue should be closed.

[nevakrien]

same issue rn on a new environment with everything baseline other than intel-pytorch-extension. tried playing with the tornado version since it helped me last time this error came up.

in genral this is really anoying because its on jupyter notebook which I use for alot of things and i see this error once a month

[MostafaaElhadidy]

pip install nbconvert==6.4.3 worked for me.

this actually worked! thanks
