Not a Directory error in CIFAR10 exercise

Seeing this as well. I solved it by making folders for classes in “train” and “test”.

Remember how we did cats and dogs in lesson 1?
train/cats and train/dogs

I wanted to see what classes we had:
cd train && find . | grep -o [a-z]*.png | sort -u && cd .

We have: airplane, automobile, bird, cat, deer, dog, frog, horse, ship, truck

I made new folders
mkdir train_ test_

I went into one of them to make our classes, created the fn to organize the files, and executed it:

  1. cd train_

  2. mkdir airplane automobile bird cat deer dog frog horse ship truck

  3. cd ..

  4. function copytrain { for arg in $@; do cp $(find train -name '*'$arg'.png') train_/$arg/; done; };

  5. copytrain $(ls train_ | grep -o "[a-z]*")

It took a few minutes to run. Lots of files.

Then repeat 1-5, but with test and test_ instead of train and train_

Now it all works. This is because that from_paths method is expecting folders for the classes.

Make sure the new folders you created match the names you provide to from_paths val_name and trn_name.
