Differences between Flatten() and Ravel() Numpy Functions
There are two kinds of methods to convert a Ndarray into a 1D array flatten() as well as Ravel()
The question here is, what is the reason there are two distinct roles to perform the same job?
Differences between Flatten() and Ravel()
P.ravel():
- Returns only the reference/view of the original array
- In the event that we alter the array, we will be able to see that the value of the original array changes too.
- Ravel is faster than flatten() because it doesn’t take up any memory.
- Ravel is a library-level function at the library level.
P.flatten():
- Return a duplicate of the initial array
- When you alter the value of this array, the original array’s value is not changed.
- Flatten() is considerably faster that ravel() because it takes up memory.
- Flatten is a method used by a ndarray.
Let’s see the difference between flatter() and ravel() function using this code.
Code:
Output:
Original array: [[3 4 5 6] [5 3 6 7]] Dimension of array: 2 The output for RAVEL [3 4 5 6 5 3 6 7] [1000 4 5 6 5 3 6 7] [[1000 4 5 6] [ 5 3 6 7]] Dimension of array 1 The output for FLATTEN [1000 4 5 6 5 3 6 7] [0 4 5 6 5 3 6 7] [[1000 4 5 6] [ 5 3 6 7]] Dimension of array 1
