Unable to open image

[Ash_reg (Ashvanth.S)]

Was trying to participate in this new community kaggle competition and where i get to use fastai.
While using this code to view the size of the image in train dataset

img = PILImage.create(files[0])
print(img.size)
img.to_thumb(128)

this is the error i receive. how to resolve this issue?
