Description
Describe the issue:
The following code seems correct, and passes type checking under 2.1.3 but not 2.2.0:
import numpy as np
rng = np.random.default_rng(27446968)
n_states = 5
P = rng.random(size=(n_states, n_states))
p = rng.random(n_states)
p = P.T @ pI suppose mypy is flagging that the float width can increase, but since float64 is used by random, that won't happen in this scenario.
Reproduce the code example:
N/AError message:
foo.py:10: error: Incompatible types in assignment (expression has type "ndarray[tuple[int, ...], dtype[floating[Any]]]", variable has type "ndarray[tuple[int, ...], dtype[float64]]") [assignment]
