Within the logs you posted, three lines are labeled “ERROR:”

ERROR: Ignored the following versions that require a different python version: 0.55.2 Requires-Python <3.5
ERROR: Could not find a version that satisfies the requirement torch==2.0.1+cu121 (from versions: 2.5.0, 2.5.1, 2.6.0, 2.7.0, 2.7.1)
ERROR: No matching distribution found for torch==2.0.1+cu121

Did you set the version of Python when you deployed the app?

3

I may not have done that because when I write pip show python on my VsCode it didn’t show a version. If anything how do I set the python version?

4

The link provided in the previous post shows how to set the version during deployment. You can also access your app’s settings from your app dashboard.

Thank you!
