Hi,

I have the same issue. Has anyone found a fix for it yet?

For more information when I run the rendered notebook it works fine, its only during the metaflow card execution that i receive a Keyboard Interrupt: error with no other information

[mustfkeskin]

I solved this by running runs with the papermill library. Metaflow also uses this in the background, but it timeouts. Since I couldn't find timeout parameter, I ignored metaflow for now.

[JonathanBroadbent]

Thanks for the information. Can you describe to me a bit more?

How do you use the papermill library? Are you still including your notebooks in the metaflow UI or did you abandon metaflow completely?

[valayDave]

you can set timeout in the @card decorator to set timeouts for longer execution of the notebook.
