correct and efficient way to flatten array in numpy in python?
28 Dec 2025 at 5:01am
46 You might need to check out numpy.flatten and numpy.ravel, both return a 1-d array from an n-d array. Furthermore, if you're not going to modify the returned 1-d array, I suggest you use numpy.ravel, since it doesn't make a copy of the array, but just return a view of the array, which is much faster than numpy.flatten.

Here flatten demonstrates piecewise linear complexity which can be reasonably explained by it making a copy of the initial array compare to constant complexities of ravel and reshape that return a view. It's also worth noting that, quite predictably, converting the outputs .tolist() evens out the performance of all three to equally linear.
How to 'Flatten' in Adobe Acrobat Pro DC

We recently purchased Adobe Acrobat Pro DC and I'm trying to figure out how to take a document that I added a stamp to and flatten it so our users cannot delete the stamp from it. I have found the 'Flatten' option but it is greyed out. The only option in the menu available is 'Import as Layer'. H...

For example, if you have a batch of images and you call torch.nn.Flatten, the typical use case would be to flatten each image separately, and not flatten the whole batch. If you do want to flatten all dimensions using torch.nn.Flatten, you can simply create the object as torch.nn.Flatten(start_dim=0).
What is the role of "Flatten" in Keras? - Stack Overflow
27 Dec 2025 at 4:22pm
The role of the Flatten layer in Keras is super simple: A flatten operation on a tensor reshapes the tensor to have the shape that is equal to the number of elements contained in tensor non including the batch dimension. Note: I used the model.summary() method to provide the output shape and parameter details.

Conclusion: To flatten an arbitrarily nested array in a functional way we just need a one-liner: const flatten = f => traverse(f) (concat) ([]);. All other involved functions are generic and have a whole range of other potential applications.

How to flatten only some dimensions of a numpy array
1 Jan 2026 at 12:41pm
Is there a quick way to "sub-flatten" or flatten only some of the first dimensions in a numpy array? For example, given a numpy array of dimensions (50,100,25), the resultant dimensions would be (...
When would you use `flatten ()` instead of`reshape (-1)`?
29 Dec 2025 at 11:01pm
flatten returns a copy of the array. reshape will return a view if possible. So, for example, if y = x.reshape(-1) is a view, then modifying y also modifies x:
