Hi!
Got stuck early on trying to use lesson2-image_models.ipnb with nih-chest-xrays dataset
UPD: already solved this.
My csv looked like this:
!cat 'data/labels.csv'
Image Index,Finding Labels
00000001_000.png,Cardiomegaly
00000001_001.png,Cardiomegaly|Emphysema
00000001_002.png,Cardiomegaly|Effusion
00000002_000.png,No Finding
00000003_000.png,Hernia
...
Just had to edit it, delete spaces in "no findings’ and replace “|” sign with spaces.
