Is the Escher widget compatible with JupyterLab 3?

[danolson1]

I can get the Escher widget to display correctly in JupyterLab v 2.2.6, but not in v. 3.0.11. In that version, I get an error message "Error displaying widget: model not found."

Has anyone else gotten the Escher widget to work in JupyterLab v3? Is this a known issue?

Same problem with JupyterLab 3.0.14

same problem with Jupyter 3.0.16!! @danolson1 did you somehow manage to fix the issue in v. 3? or did you end up using v 2.2.6?

[danolson1]

I set up an environment with jupyterlab 2.2.6 for Escher work

Ok, just tried using 2.2.6 instead. widget still not showing up, did I miss anything in my code? - I'm new to escher and jupyter, would really appreciate some help :)

[danolson1]

There are a lot of possible problems. I teach a Metabolic Engineering class to graduate students at Dartmouth College. I've attached the MS Word document that I use to help them get their environments set up as well as a Conda environment file. Give that a try and see how it goes.

That would be really helpful! Thank you so much. Although I can't seem to find the attachment.. @danolson1

me21_v5.zip See if this works.

[parsanayyara]

Yep, it works for me! I think the problem was probably in the conda set up. I seriously can't thank you enough!

thanks for the help. i've been struggling with it today after some jupyter updates. I aslo had to install @jupyter-widgets/base before escher extension (otherwise, it wouldn't build) and reinstall @jupyter-widgets/jupyterlab-manager after escher extension.

Hi I am trying to set up per @danolson1 solution but the Jupyter lab build is failing, and the instructions do not work anymore. How can I set up an environment for escher in 2024?

[parsanayyara]

Still works for me. How is jupyter lab failing?
