module 'numpy.typing' has no attribute 'NDArray'

[COMoER]

When importing nashpy module, an error occurs that "module 'numpy.typing' has no attribute 'NDArray'". The version of Numpy is 1.20.1 the version of python is 3.8.8 and the version of Nashpy is 0.0.30. When I install the version 0.0.25 of Nashpy, I import the module successfully.

The whole log of this error is:

I have found the cause. The expression 'numpy.typing.NDArray' is new in version 1.21 of numpy. But I successfully installed Nashpy using 'pip' method.
