P.S : For some of the native libraries I used .whl files instead of building them myself using chquopy build tools as the build errors associated with the libraries were not coming up by using .whl files for installation instead of using pip with pypi. Can that be cause of the error?

Thank you all for the support!

Only android and any wheels will work on Android, not manylinux wheels.

I'm not sure how your build completed, since we don't have any OpenCV builds for Python 3.10. But if you change the version to 3.8, you should be able to install all of the packages in your list except for onnxruntime (#216) and safetensors. To do this, simply list the package names, e.g. install "numba".
