How to add azure-ai-formrecognizer --pre to requirements.txt

Question

Hi there, I am developing a python program with azure formrecognizer API. The program will be run and accessed via Azure functions. I used the formrecognizer version V2.1, which supports the analysis of business card.

When I put azure-ai-formrecognizer --pre in the requirments.txt it cannot be recognized by pip(only azure-ai-formrecognizer is able to be imported). I have to install it manually by pip install azure-ai-formrecognizer --pre. I can do that on my machine, but what I want is deploying this program on Azure functions, where I have to resolve the dependency via requirements.txt.

How can I solve this problem? Many thanks in advance!

pip version:20.1.1
python version 3.8
