Recursion error; fastai v1.0.27, Windows 10

I don’t see the data_block.py code patches in the master. Am I looking in the right place ? The patch does work for me on windows though, along with the:

data.train_ds.y.items = np.int64(data.train_ds.y.items)
data.valid_ds.y.items = np.int64(data.valid_ds.y.items)

changes in the notebook. Well done quantotto !
