1、问题： 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
2、解决方法[参考]
conda list
降低numpy 版本：
pip uninstall numpy
pip install numpy==1.23.5
