mypy失败了numpy总和
此代码片段有效：
py -c "import numpy; print(numpy.array([[1,2,3],[4,5,6]]).sum(axis=0) % 2)"
[1 1 1]
但是Mypy出现了一个错误：
py -m mypy -c "import numpy; print(numpy.array([[1,2,3],[4,5,6]]).sum(axis=0) % 2)"
<string>:1: error: Unsupported operand types for % ("number[Any]" and "int")
<string>:1: note: Left operand is of type "Union[number[Any], ndarray]"
Found 1 error in 1 file (checked 1 source file)
这是我的代码段中的mypy错误还是numpy错误或错误？
This code snippet works:
py -c "import numpy; print(numpy.array([[1,2,3],[4,5,6]]).sum(axis=0) % 2)"
[1 1 1]
But mypy gives an error:
py -m mypy -c "import numpy; print(numpy.array([[1,2,3],[4,5,6]]).sum(axis=0) % 2)"
<string>:1: error: Unsupported operand types for % ("number[Any]" and "int")
<string>:1: note: Left operand is of type "Union[number[Any], ndarray]"
Found 1 error in 1 file (checked 1 source file)
Is this a mypy bug or a numpy bug or a bug in my code snippet?

这是一个麻烦的错误，直到numpy 1.20.3 https://github.com/numpy/numpy/numpy/问题/18305
