[BUG] rich.print failed when class supports __rich_repr__ and need to compare numpy.ndarray with None

[kahojyun]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Describe the bug

import rich.repr
import numpy as np
import rich


@rich.repr.auto
class A:
    def __init__(self, arr=None) -> None:
        self.arr = arr


if __name__ == "__main__":
    a = A(arr=np.array([1, 2, 3]))
    rich.print(a)

What platform (Win/Linux/Mac) are you running on? What terminal software are you using?

I may ask you to copy and paste the output of the following commands. It may save some time if you do it now.

If you're using Rich in a terminal:
