报错：‘numpy‘ has no attribute ‘float‘._attributeerror: 'numpy.ndarray' object has no attr

报错：

'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.

报错原因：

从numpy1.24起删除了numpy.bool、numpy.int、numpy.float、numpy.complex、numpy.object、numpy.str、numpy.long、numpy.unicode类型的支持。

解决办法

方法一：修改numpy版本
安装numpy1.24之前的版本

pip install numpy==1.23.5

方法二：修改代码

np.float替换为float或者np.float64/np.float3
