The code will not work with numpy>=1.24

Reference for the deprecation: https://numpy.org/devdocs/release/1.20.0-notes.html#using-the-aliases-of-builtin-types-like-np-int-is-deprecated

When using paddleocr with the previous numpy versions (<1.24), it just raises some DeprecationWarning. However, numpy has officially removed them in the version 1.24 and onward (>=1.24).

Aside from np.int, np.bool8 would be considered as well
