在使用librosa库时遇到`DeprecationWarning:np.float is a deprecated alias for the builtin float.`警告。该警告源于numpy版本过高，建议将numpy版本回退到1.19.3以消除警告。这样做不会改变任何行为且是安全的。如果你需要numpy的浮点类型，应使用np.float64。

DeprecationWarning: np.float is a deprecated alias for the builtin float.

报错：DeprecationWarning: np.float is a deprecated alias for the builtin float. To silence this warning, 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.

环境中 librosa==0.7.0
解决方案：将numpy版本下调只1.19.3

是内置float的不推荐别名。要去除这个Warning，需要单独使用float。是将要被弃用的，可以用。

警告：`np.float` 是内置类型 `float` 的一个已弃用的别名。为了消除这个警告，请直接使用 `float`。这样做不会修改任何行为，是安全的。如果你确实需要使用 numpy 的标量类型，请在这里使用 `np.float64`。

而它已经被弃用，不再是 NumPy 的属性。为了避免这个错误，你应该将。如果你需要使用特定的 NumPy 标量类型，可以使用。这个错误表明在代码中使用了。

这个错误是因为numpy的较新版本中移除了对np.float的支持。在NumPy 1.20中，np.float被弃用并建议改用float或np.float64。错误的根本原因在于代码中调用了。
