Hi all,
I am new to fastai. I am running the planet code on different dataset and trying to create a submission file.
I have a question about probs.shape
v.s. len(data.test_ds.fnames)
since probs.shape
returns # (n_images, n_classes), is the n_images supposed to be the same as what returned by len(data.test_ds.fnames)
?
I have probs.shape (7186, 226) and len(data.test_ds.fnames) 39706
I have this question because when I run
df.insert(0, 'id', [o[5:-4] for o in data.test_ds.fnames])
I am getting this:
ValueError: Length of values does not match length of index
I also tried:
submission = pd.DataFrame({'file' : os. listdir(f'{PATH}test'), 'labels' : preds_classes})
and got:
ValueError: arrays must all be same length
the test images in the test folder are 39705.
during the training process (learn.fit), I accidentally deleted some images in the test folder but I put them all back right after. I don’t know if that’s the reason why i only have 7186 images in probs.shape? or the reason why I am getting not the same length error?
Would like to know how I can fix this, thank you.
