Image URL is not accessible

JingjingShii commented 3 years ago

When trying to run ml landmarks azcv https://bit.ly/3vnuG24 under azcv package (this command line is found in chapter 6.3 https://mlhub.ai/survivor/azcv-quick-start.html), I got the error:

Some sites block anonymous agent access.

The landmark command of the git repository gjwgit/azcv needs to be updated to set the User Agent to be Mozilla/5.0 as is done in mlhub/utils.py and mlhub/commands.py.

This is a general issue and perhaps we need a general mlhub function to download a file from a URL after setting the User Agent appropriately.

After the value error is fixed in the type function, the result of ml type azcv https://bit.ly/3bNGSB is Image URL is not accessible as well.

Some bit.ly short links work just fine. But not this one:

$ ml landmarks azcv https://bit.ly/3vnuG24
Traceback (most recent call last):
  File "landmarks.py", line 64, in <module>
    analysis = client.analyze_image_by_domain(domain, url, language)
  File "/home/gjw/.local/lib/python3.8/site-packages/azure/cognitiveservices/vision/computervision/operations/_computer_vision_client_operations.py", line 400, in analyze_image_by_domain
    raise models.ComputerVisionErrorException(self._deserialize, response)
azure.cognitiveservices.vision.computervision.models._models_py3.ComputerVisionErrorException: Image URL is not accessible.

This one works just fine:

$ ml landmarks azcv https://bit.ly/3lfNVG6
0.94,Colosseum

Is it the final server where the image actually is is rejecting the short link? A wget works just fine.

Close this now - It is Azure calling through to the end image site via the bitly link. Somewhere along the way it is being blocked.

Note that locally the following works just fine:

$ wget https://bit.ly/3vnuG24 -O tmp.png
