Azure Python Web App Internal Server Error

Question

EDIT: The problem seems to be the importing of packages in my app. All the packages are correctly installed, and i can see them in my wwwroot with kudu. But, when i import them in the scripts, i get the 500 error. The WIERDEST thing is that the problem only occurs when i import the packages this way:

from package import something

But not this way:

import package

I also get the same error, when i try to call a package function, meaning i cant access anything from the packages(?)

It seems that there is an exception generated in web app, but not in my local machine. Any thoughts?

I'm trying to publish a Python Web App in Azure Web Apps, but I keep failing. I'm using bottle as the web framework, and the packages i installed, along with their dependencies are:

• Numpy
• Scipy
• Scikit-image

I have configured the virtual env to match the web app (32bit/2.7), and i installed the packages using wheels as mentioned in this post: https://azure.microsoft.com/en-us/documentation/articles/web-sites-python-create-deploy-bottle-app/

I'm deploying the app via VS and the publish wizard from Azure SDK, and everything works as expected.

When the app is up, i get a 500 error, and the console says these things:

My web.cofing is this:

Any help why this might happening?

FINALLY, i got it working. The problem was the version of pip i was using to install the wheels. After i upgraded to pip 8.11.1 everything worked as expected.
