Update requirements.txt File

[AntiiRain]

Changes Made

• Updated requirements.txt to add version constraints for protobuf < 3.20 and numpy < 1.20, to avoid issues caused by deprecated functionalities in newer versions.
• Ensured that the project environment can now be set up using pip install -r requirements.txt without errors.
• The changes were tested on two different devices, and the project runs as expected on both.

Reasons for the Changes

• Protobuf Version Issue:

  • When installing newer versions of protobuf (e.g., version 5.28.2), the following error occurs:

    If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
    
    If you cannot immediately regenerate your protos, some other possible workarounds are:
      1. Downgrade the protobuf package to 3.20.x or lower.
      2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).
    

  • To resolve this, I added a constraint to limit protobuf versions to < 3.20 in the requirements list.

• NumPy Version Issue:

  • When installing newer versions of numpy, an error occurs in TensorFlow 2.2 due to deprecated functionality:

    AttributeError: module 'numpy' has no attribute 'object'.
    
    `np.object` was a deprecated alias for the builtin `object`. To avoid this error in existing code, use `object` by itself. Doing this will not modify any behavior and is safe.
    

  • The alias was deprecated in NumPy 1.20, as noted in the release documentation: NumPy 1.20 Deprecations.
  • To fix this, I updated the version requirement to numpy>=1.14.3, < 1.20.

Testing

• The updated dependencies were tested on two devices, and the environment configured using pip install -r requirements.txt worked without any issues on both.
