Hey @arafune,

This looks like an issue with the bokeh and tornado version. Jupyter also uses tornado I believe, and so if Jupyter is installed in the same environment this can create an incompatibility.

I'll look into how to address this long term, but I would advise trying the curve fitting workflow I advocated in the previous thread since it's very efficient (and doesn't depend on what you did in some UI window so it's easily reproducible and visible in the notebook).

Did my comments in that other thread make sense? I should probably add a second tutorial notebook on curve fitting sometime.

Best, Conrad

Hi @chstan,

Your comments are arguably useful (you are the author/owner of pyarpes). But a bug is a bug, and I think it should be reported.I think it is important when using open source software for analysis to check whether the software is being actively developed.

It is important from a practical point of view to say, "If you do this, you can avoid the problem". However, if we only use such a solution, we will have to verify the reliability of the analyzed results in a different way. And I would be less likely to recommend it to my students.

Ideally: we would have a solution that would

Best,
