Bokeh and jinja2 version conflict

[scizen9]

The current bokeh version specified in the environment.yml file requests bokeh~=2.0.0, but does not specify a version for jinja2, which is a dependency. The version of bokeh that installs uses the jinja2.Markup class which was deprecated in jinja2 v3.1, so if conda installs jinja2 version 3.1 or higher, the pipeline will crash trying to load jinja2.Markup.

We should either update the bokeh requirement to a version of bokeh that uses markupsafe.Markup, or specify jinja2=3.0.3, which was the last version with jinja2.Markup. Probably an update to bokeh >= 2.3.2 would solve this issue.

I had the same error, and installing jinja2=3.0.3 solved it. Thanks for posting the issue!

Thanks for posting, I had the same error! Couldn't get the pipeline to run without this.
