Hi,

I'm total AI newbie trying to run your piece of code, but i'm getting error. Any hint about that ?

Have you added or changed anything ?

[jfburdet]

Nothing modified, only clone, pip install and run.

I also tried to run with my "own" dataset generated running grabber.py for a few days, giving the same error.

Try to convert the data list to a numpy array, and play with the shape.

[jfburdet]

I thought at first it would work out of the box. Anyway, that will make a good hand on for me.
Cheers.

Some library must have been updated.

If you understand what's the problem, let me know.
