AttributeError: module 'numpy' has no attribute 'float'

I got the following error when using the BYTEtracker.update() method.
Here are the error details:

AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations```

A temporary way to bypass: np.float = float

@ahmadshah2103 can you fix the problem? helpe me plase! I have the same problem :(

[ahmadshah2103]

@kevinpal10 you can change it in the source code, it worked for me.
OR
you can try @qrsforever solution.

[kevinpal10]

@ahmadshah2103 thank youu!! It's working!

[thecetin]

->ByteTrack -> yolox -> tracker -> byte_tracker.py and matching.py

In these two .py files you should change "np.float" to "float"
OR
in the requirements.txt file numpy version should be 1.22.4 or lower version!

[ahmadshah2103]

@thecetin Thank you for providing the details.

didnt work for me showing same error even after changing np.float in byte_tracker.py and matching.py

@rahul12st Try this one.
