  --- BEGIN ISSUE ---
  Dependency versions error
  #### Issue description
  I made a fork of this project and tried to setup a new virtual environment.
  
  ```
  python -m venv sf-venv
  source sf-venv/bin/active.fish
  pip install -r requirements.txt
  ```
  
  However, I got the following error
  ``` 
  ERROR: Cannot install -r requirements.txt (line 4) and numpy>=1.20 because these package versions have conflicting dependencies.
  
  The conflict is caused by:
      The user requested numpy>=1.20
      tensorflow 2.5.0 depends on numpy~=1.19.2
  
  To fix this you could try to:
  1. loosen the range of package versions you've specified
  2. remove package versions to allow pip attempt to solve the dependency conflict
  
  ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies
  ```
  
  #### Additional information
  
  If it helps, I am using Python 3.9.4 and pip 21.1.1. 
  
  A quick fix would be to downgrade the version of numpy in requirements.txt and solve the issue, but I am not sure it is the best way to go.
