title: Error from Azure function: ModuleNotFoundError
body: <p>I followed the official documentation to set up my requirements.txt file. My understanding was that the function should be able to use modules if they are in requirements.txt. Here is an example of what that file looks like, with all the modules and their versions written in this way:</p>
  
  <pre><code>azure-common==1.1.12
  azure-keyvault==1.0.0
  azure-mgmt-keyvault==1.0.0
  azure-mgmt-nspkg==2.0.0
  azure-mgmt-resource==1.2.2
  azure-storage-blob==12.3.1
  azure-mgmt-subscription==0.5.0
  azure-mgmt-network==10.2.0
  azure-functions==1.2.1
  </code></pre>
  
  <p>However, when I look at the function's logs, I can see that it keeps throwing the error, "ModuleNotFoundError: No module named 'azure.common'". This is the first module I try to import in <code>__init__.py</code>. What am I doing wrong?</p>
