I am running:

path = Path('/content/drive/MyDrive/X-Ray_Image_DataSet')
np.random.seed(41)
data = ImageDataBunch.from_folder(dta, train="Train", valid ="Valid", ds_tfms=get_transforms(),size=(256,256), bs=32, num_workers=4).normalize()

And I am getting this error:

/usr/local/lib/python3.7/dist-packages/fastai/data_block.py:458: UserWarning: Your training set is empty. If this is by design, pass `ignore_empty=True` to remove this warning.

During handling of the above exception, another exception occurred:

It's either because your data source is empty or because your labelling function raised an error.

  • Your training set is empty. Probably because you forgot to provide the path to the dataset in function. – SaGaR Sep 20 '21 at 04:32

np.random.seed(41)
data = ImageDataBunch.from_folder(path, train = '.', valid_pct=0.2,
        ds_tfms=get_transforms(), size=(256,256), bs=32, num_workers=4).normalize()

you can use this instead of that
