Successfully built bytetracker
Installing collected packages: lap, typing-extensions, numpy, torch, scipy, bytetracker
DEPRECATION: lap is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at pypa/pip#8559

[kadirnar]

pip install numpy

[swdee]

I received the same error and fixed it with.

pip install numpy==1.25.2

Then run install again.

pip install bytetracker

I am running Python version 3.9.
