Hi everyone!
I’m using fastai2.medical.imaging in the current Hemorrhage competition on Kaggle. A kernel that worked perfectly yesterday now fails to load the libraries (in particular, the module “kornia”.

Here is the error message :

ModuleNotFoundError Traceback (most recent call last)

6 from tqdm import tqdm_notebook

ModuleNotFoundError: No module named ‘kornia’

I tried to look on the forum to see if anybody had already reported this and didn’t find anything. Apologies if I missed it somewhere (or if that’s not the correct place to report this).

I think it was just added to fastai2 in the last day or so, adding the below fixed it for me (using GCP)

!pip install git+https://github.com/arraiyopensource/kornia

Just pip install kornia should suffice.
