遇到AttributeError: module 'numpy' has no attribute 'float'

AttributeError: module '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.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

 

原因：

numpy在1.24以后弃用了float类型。

 

 

解决：

　　重新安装numpy <1.24版本的

具体操作：

1.卸载

pip3 uninstall numpy

2.指定版本安装：

pip3 install numpy==1.23
