correct and efficient way to flatten array in numpy in python?
27 Feb 2026 at 2:47pm
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.

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
27 Feb 2026 at 4:03am
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 (...

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 does the list comprehension to flatten a python list work?

1 Note, of course, that the sort of comprehension will only "flatten" a list of lists (or list of other iterables). Also if you pass it a list of strings you'll "flatten" it into a list of characters.

33 This version of flatten avoids python's recursion limit (and thus works with arbitrarily deep, nested iterables). It is a generator which can handle strings and arbitrary iterables (even infinite ones).
What is the role of "Flatten" in Keras? - Stack Overflow
28 Feb 2026 at 12:20am
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.
How to 'Flatten' in Adobe Acrobat Pro DC
9 Jan 2026 at 2:19pm
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'. How do I enable the 'Flatten' feature? In previous versions, I used a java script to flatten when ...
