I have tried two things that I saw on line.

1. Use fastai v1 in program
2. put from fastai.vision import * in import file area.

neither one will work.

I am at a loss to find a way to correct this error.

Any help appreciated.

Respectfully,

Where is the class supposed to come from? Have you checked the documentation for the library to see whether you've got the class name correct and that you're importing the right package? Make sure you check the docs for the version you're using, as perhaps things moved between versions.
