module ‘numpy‘ has no attribute ‘int‘.

报错：

AttributeError: module 'numpy' has no attribute 'int'.
`np.int` was a deprecated alias for the builtin `int`. To avoid this error in existing code, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information

解决方法：

1. 使用numpy 1.20及以下版本（1.20.3比较稳定）

pip uninstall numpy
pip install numpy==1.20.3

2. 使用使用numpy==1.23.5

pip uninstall numpy
pip install numpy==1.23.5

若使用numpy 1.20以下版本出现问题：

ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

提示numpy版本过低，则使用方法2，安装numpy=1.23.5
