Hello ISV developers,

I downloaded a copy of ISV to try out for the first time, and it took me a while to get it operational due to dependency-related issues. Specifically, some of the dependencies have had breaking changes since ~2019, so I experimented with pinning to older dependency versions until I eventually got a combination that worked. I even had to use python v3.8 instead of v3.10 due to some deprecations. If it is useful for you, I've included my pip install command with the versions pinned that worked for me:

pip install jinja2==2.10 pyyaml argparse tornado==4.5.3 numpy bokeh==0.12.14 pandas==1.3.5 selenium pillow ase markupsafe==2.0.1

After installing these pinned versions, it started working and I was able to run the example described in the README! I'm having fun exploring this example, and I do like that you included the interactive tour of its features.

I did spend some time attempting to migrate the code to a later version of Bokeh, but it seems that the Bokeh interface has quite a few differences between 0.12.14 and 3.3.1. For now, sticking with these older dependencies works fine for me since it seems like updating the code for compatibility with the latest dependencies would take a good chunk of effort.

Based on my experience here, would you be able to please update the README with fully pinned versions of all the dependencies so that future dependency updates don't introduce any more breaking changes?

Thanks for looking into this issue and for developing such a useful tool!

P.S. If you are interested in the specific deprecations per dependency, here are each of the breaking changes that I encountered:

• python3 version must be below v3.10 due to ImportError: cannot import name 'Mapping' from 'collections'. I was able to successfully use python v3.8.
• bokeh due to ImportError: cannot import name 'TabPanel' from 'bokeh.models.widgets' and many other similar issues
• pandas due to AttributeError: 'DataFrame' object has no attribute 'iteritems'
• markupsafe due to ImportError: cannot import name 'soft_unicode' from 'markupsafe'
• jinja due to ImportError: cannot import name 'Markup' from 'jinja2'
