Using Python packages in Azure function code

Question

I've created an Azure function and want to be able to use various packages in the Python code for the function; take Numpy, for example. Obviously, the code is not going to run from my local machine once it's published to Azure. This means I can't install Numpy to whatever infrastructure it runs on, so I can't import Numpy in my code. How can I use a package like Numpy in the code?

Answer 1

From the official doc:

Dependencies are obtained remotely based on the contents of the requirements.txt file

All you need to do is create that file and upload it together with your Function code
