[Documentation] Requirements for building a layer should be in a separate file

[dgard1981]

I've just added a layer for aws-xray-sdk and jsonpickle as described in the README for the blank Python project.

cd function
pip3 install --target ../package/python -r requirements.txt

However, I was finding that the function package still included the required modules as listed in requirements.txt. It looks as though that rather than building the layer from /functoin/requirements.txt a separate requirements file should be created, and that modules that will be in the layer should be removed from /functoin/requirements.txt.

Can the documentation be amended to make this clear, as the existing documentation doesn't seem to acknowledge that at all.

Hi David, the packages should appear in a package folder under blank-python and be uploaded separately when you run the deploy script. If you look in your S3 bucket there should be one file for the layer (13MB) and one for the code (3KB). Check your function folder to make sure that there aren't any packages in there.
