the underlying cause of getting the error message of Reason: "broken data stream when reading image file"

[wine lover]

Hi, 

I am trying to test the skimage by running the following python script

from skimage import io
data = io.imread("./test_data/tiger.jpeg")print(data.shape)


It gives the following error messages. What can be the reason? Thank you 
very much for the help.


bash-4.1$ python test.py

During handling of the above exception, another exception occurred:
