Error displaying widget: model not found

[grant-westfall]

Hello! I'm new to Mercury, and I'm getting this error message when I run the following: dlr_selection = mr.Select(choices=df['DlrNm'].to_list(), label="Dealer choice") Error displaying widget: model not found

Any ideas about how I can fix this?

Hi @grant-westfall,

Thank you for reporting the issue.

Please try to use the following code:

dlr_selection = mr.Select(choices=list(df['DlrNm'].unique()), label="Dealer choice")

If you still have a problem:

• please include all code to reproduce the issue,
• please run pip freeze to show all packages that you have installed.

Here's a screenshot of my code. pip freeze returned the following:

Thank you @grant-westfall. I think you paste only half of the pip freeze output. Could you please paste full output?

I see that you have Django==3.2.5, in the newest version of mercury the Django should be above version 4.0. Please try to update mercury:

pip install -U mercury

[grant-westfall]

Thanks for the quick responses! Updating mercury didn't update Django above version 4.0, here's the relevant output:

pip install -U mercury

OK, I see the problem. You have Python 3.7. Please update Python version to at least 3.8 version and then please update mercury. We support Python version 3.8 - 3.11.

[grant-westfall]

Oh, that'll do it. Thanks for your help!

[pplonski]

Please let me know if you make it works.

May I ask what are you building? What is your use case? and how have you found Mercury?

[grant-westfall]

Will do! I'm working on a web app that'll allow our sales team members to easily view and understand some analysis of my team's modelling results. I came across Mercury from this article: https://towardsdatascience.com/create-a-web-app-from-your-jupyter-notebook-with-mercury-21239b7abb37.

[pplonski]

Im closing the issue. If you still have a problem please reopen.
