flatten
(*args, **kwargs)[source]¶ Flatten axes of the data.
Any subset of the axes may be flattened.
The shape of the data may change, but the size will not.
The flattening is executed in rowmajor (Cstyle) order. For example, the array
[[1, 2], [3, 4]]
would be flattened across both dimensions to[1 2 3 4]
.New in version 3.0.2.

None

 Returns
Examples
>>> f.shape (1, 2, 3, 4) >>> f.flatten().shape (24,) >>> f.flatten([1, 3]).shape (1, 8, 3) >>> f.flatten([0, 1], inplace=True) >>> f.shape (4, 2, 3)
