                Hi, 
I’m not sure if it will ever affect the training. 
I was able to get rid of the warnings by using a script to remove all exif data with the piexif library. 
The script below didn’t work at first because one of the JPEG’s is actually a PNG. You can fix that with ImageMagick: 
mv n02105855/n02105…
