pyimagecourse's Issues

download_data.py "No healthy IP available for the backend"

Hi @guiwitz
I just wanted to try out your course (thanks a lot for making this available).
But I failed installing the data part, due to a lost link in your download_data.py file.
It is following link:
url = 'https://img.myswitzerland.com/671846/407'

which gave me following error:
[...]$ python installation/download_data.py
Traceback (most recent call last):
File "installation/download_data.py", line 14, in <module> urllib.request.urlretrieve(url, where_to_save+'Klee.jpg')

I hope you can fix this, I am looking forward to follow your course!
Bests,
