dtype=np.int报错问题

有一行代码c = np.fromfile("b.dat", dtype=np.int, sep=",")  运行时报错，内容如下：

 DeprecationWarning: `np.int` is a deprecated alias for the builtin `int`. To silence this warning, 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.
Deprecated in NumPy 1.20; for more details and guidance: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
  c = np.fromfile("b.dat", dtype=np.int, sep=",")

原因：numpy1.20开始已经将np.int废弃了，check了一下自己的版本，果然

 numpy版本已经到1.23.2

解决办法：改成np.int16/np.int32 直接指定到具体的字节 或者改为np.int_

再次运行，问题解决！
