Keyerror: Class 'numpy.object_' While Downloading Image Dataset Using Imread

I am trying to download images from URLs using imread. After downloading about 700 images, I see KeyError: class 'numpy.object_' . I am really not familiar with numpy and Conda lib

Solution 1:

Edit

I reproduced your results with:

from skimage import io
url = "https://requestor-proxy.figure-eight.com/figure_eight_datasets/open-images/test/f54ecb040198098c.jpg"
img = io.imread(url)

print(img.shape)

Turns out, this actually returns two images or layers of the same image, where img[0] is the actual image you want, and img[1] is some faulty reading in Pillow (the module skimage is using to read images).

Check this issue out.

For now, some quick workaround should be fine.

if img.shape[0] == 2:
  img = img[0]

Could you show the URL that triggers this error? It could be your formatting on url[-20:] that adds some funky extension. Also, I'd recommend just printing img and img.shape and img.dtype to have a better idea of what's going on.
