I have been trying to install PaddleOcr in my system. When I download the requirements.txt, I get an error 'Failed building wheel for lanms-neo' and 'failed building wheel for Polygon3'.

Building wheels for collected packages: lanms-neo, Polygon3
  Building wheel for lanms-neo (pyproject.toml) ... error 
  error: subprocess-exited-with-error 

  × Building wheel for lanms-neo (pyproject.toml) did not run successfully.

Failed to build lanms-neo Polygon3
ERROR: Could not build wheels for lanms-neo, which is required to install pyproject.toml-based projects

I tried installing Visual studio installer for Desktop development with c++ for the building tools but I couldn't solve the error still.
