WebJul 21, 2010 · numpy.reshape. ¶. Gives a new shape to an array without changing its data. Array to be reshaped. The new shape should be compatible with the original shape. If an integer, then the result will be a 1-D array of that length. One shape dimension can be -1. In this case, the value is inferred from the length of the array and remaining dimensions. WebAs explained here a key difference is that: flatten is a method of an ndarray object and hence can only be called for true numpy arrays.. ravel is a library-level function and hence can be called on any object that can successfully be parsed.. For example ravel will work on a list of ndarrays, while flatten is not available for that type of object. @IanH also points out …
