What is the role of "Flatten" in Keras? - Stack Overflow
Flatten make explicit how you serialize a multidimensional tensor (tipically the input one). This allows the mapping between the (flattened) input tensor and the first hidden layer. If the first hidden layer is "dense" each element of the (serialized) input tensor will be connected with each element of the hidden array.
correct and efficient way to flatten array in numpy in python?
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.

How to 'Flatten' in Adobe Acrobat Pro DC - Adobe Support …
2016年1月6日 · Places a menu item in the Edit menu called "Flatten" - WAY WAY WAY faster than any of the built-in options. Alternatively, Foxit Phantom PDF has a nice implementation of Flatten, but they haven't implemented the full Adobe standard yet, so it may not be the best option if you need to do things like use digital signatures and/or view 3D PDFs.
python - Understanding torch.nn.Flatten - Stack Overflow
2021年5月9日 · 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).
svg - How to "flatten" in Inkscape? - Stack Overflow
2020年5月30日 · I know that Inkscape has no flatten function. But. I have three objects in an svg file, which I want to all merge into one. It's a contribution to the Material Design Icon catalog, so this has to be a single path SVG. However, when I "Union" the objects, two of the inner objects become thinner. If I "Combine" them, the outer object becomes fatter.
How to flatten only some dimensions of a numpy array
2013年9月12日 · @SebastianHoffmann, numpy's flatten too would manage. Flatten, as implied by the function's name, flattens the tensor/ndarray into a 1-D array. So there is *no ambiguity that needs resolving. Whereas the issue discussed here is the flattening of a single dimension, e.g. a 6-D into a 5-D tensor/ndarray.
python - Numpy flatten RGB image array - Stack Overflow
2016年5月1日 · Flatten() and reshape() are be lossless. The dimensions of the resulting array should always multiply to be the same total. Flatten has a shape() as a 1-D array, not an n-D array, hence no second value for its shape. It looks like array([1, 2, 3,]).
How does the Flatten layer work in Keras? - Stack Overflow
A Flatten layer in Keras reshapes the tensor to have a shape that is equal to the number of elements contained in the tensor. This is the same thing as making a 1d-array of elements. For example in the VGG16 model you may find it easy to understand:
When would you use `flatten ()` instead of`reshape (-1)`?
2019年9月8日 · 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:
