Cython API Runtime Error

Hello,

I am upgrading an existing C++/Cython/Python library written on Arrow
0.16.0 to
2.0.0. The build completes successfully, but I am getting the following
error when importing modules in my library.

*AttributeError: module 'pyarrow.lib' has no attribute '_Weakrefable' *

I use PyArrow Cython API in wrapping and unwrapping objects as well.

Is this due to a Cython version mismatch or any upgrading options missing
from my end?

The Cython version used here is 0.29.21.
