Sounds like you have something in there that isn’t an image.
but,i myself has put every image into the folder. uploaded to aws from jupyter notebook
does i have to manually check every folder again to find the culprit ,or is there any technique which can guide

Immediately after the exception type %debug in a cell to open the python debugger. There you can find out what is the issue. Here’s some tips on how to use the debugger after it’s popped up https://pythonconquerstheuniverse.wordpress.com/2009/09/10/debugging-in-python/

This error sometimes occurs because of other reasons too - Check that your Folder Names (in Train or Validation) have NO spaces in them.

I check the sizes of Images, by opening each image and checking its size as below. If this is useful, I can create a pull request to act as an utility Function.
@naveenmanwani - You can use this for now to see if it helps you find the image that’s the problem.

Hey…Please Don’t @ people unless they are the only ones who know this issue (I certainly don’t know). Because then others who may have answers might not respond to your question
Also run the code I put here to check the image sizes.

check indentation and try running that code… and in terms of image names, I am not sure but try removing the space in the name.

Try thisdataset.py under fastai and do
print (fn)
Before the return
git pull to bring a fresh copy.
@jeremy I think some of the methods need to include verbosity levels to print out some of the detail for debugging.
thanks for the advice .i removed all the spaces from the image name .i got results for train set ,valid set and but when i run this same code for test set, i got this as a result defaultdict(int, {})
sir are you saying that just before this line

Put the change after line 118 and before 119 on the file
or try to investigate the value of variable fn on using the %debug keyword.
sir as you said i putted the print(fn ),then i got this as a result
this is the full list
