text: Title: Can not install Flask-Restx in ARM
  Body: ## Description:
  I am trying to create a docker image in a RaspberryPi which runs `aarch64`, but when the Docker image starts installing the Flask-Restx package, it fails.
  
  
  !!**This was working correctly 4 months ago because that was the day of my last build.**
  
  ## **Environment**
  RaspberryPi 4
  ```commandline
  $ uname -a 
  Linux RPi 5.10.10-1-ARCH #1 SMP Sat Jan 23 16:26:04 MST 2021 aarch64 GNU/Linux
  
  $ docker --version
  Docker version 20.10.2, build 2291f610ae
  ```
  
  ## **requirements.txt**
  ```text
  flask-restx==0.4.0
  ```
  
  ## **Dockerfile**
  ```dockerfile
  # Build
  FROM python:3.9 as build
  
  COPY requirements.txt /
  
  WORKDIR /pip-packages
  
  RUN pip download -r /requirements.txt --no-input
  
  
  # Prod
  FROM python:3.9
  
  COPY --from=build /pip-packages/ /pip-packages/
  
  RUN pip install --no-index --find-links=/pip-packages/ /pip-packages/*
  
  RUN pip list
  ```
  
  ## **Expected Behavior**
  Docker image can be built correctly.
  
  ## **Actual Behavior**
  Docker image fails when building.
  
  ## **Error Messages/Stack Trace**
