Not able to map actual image name with dask_image.imread

[satish-madugula]

Not able to get the respective filename by using dask-image.

import glob
import cv2
from dask_image import imread as imr

img_names = glob.glob(r'D:\dataset2\*.jpg')
imgs = imr.imread(r'D:\dataset2\*.jpg',arraytype='numpy')

print(img_names[124])  
cv2.imshow(img_names[124],imgs[124].compute())
cv2.waitKey(0)
cv2.destroyAllWindows()

For example:
img_names[124] is actually 'abc.jpg'
imgs[124].compute() loads gives me 'xyz.jpg'

also tried using sorted(glob.glob(r'D:\dataset2\*.jpg'))

• Dask version: 0.5.0
• Python version:3.7
• Operating System: windows 10
• Install method : pip

Hi @satish-madugula, I can't reproduce the behaviour you're describing here, so it's hard to know what might be going on.

1. Which version of the pims library are you using?
2. Can you try this with dask-image installed from the master branch, like this:

python -m pip install git+https://github.com/dask/dask-image.git

I make this second suggestion because there was a recent change that added an explicit sort to the filename glob:

dask-image/dask_image/imread/__init__.py

Line 76 in 63543bf

filenames = sorted(glob.glob(sfname)) # pims also does this

I'm not sure if that would make a difference, because pims should already be doing that for you, and I don't see any strange behaviour when I try dask-image=0.5.0 (I'm on Linux instead of Windows though).

Hi @GenevieveBuckley

Thanks for the response, it is working after installing dask-image using master branch.

python -m pip install git+https://github.com/dask/dask-image.git

Hm, interesting. We've been intending to make a new release, so I think I should do that sooner rather than later given the bug you've described.

Thank you for the report!
