dstack() Stack arrays in sequence depth wise (along third dimension). concatenate() Join a sequence of arrays along an existing axis. vsplit () Split array into a list of multiple sub-arrays vertically.
By reshaping we can add or remove dimensions or change number of elements in each dimension. Reshape From 1-D to 2-D ExampleGet your own Python Server Convert the following 1-D array with 12 elements into a 2-D array. The outermost dimension will have 4 arrays, each with 3 elements: ...

Every array has a natural (1D flattened) order to its elements. When you reshape an array, it isas thoughit were flattened first (thus obtaining the natural order), and then reshaped: In [54]: z.ravel() Out[54]: array([0,3,6,1,4,7,2,5,8,9,12,15,10,13,16,11,14,17]) ...
I have an array of shape (6003,) and I want to do this: data = data.reshape((data.shape[0], 3072)) However, I am getting this error: cannot reshape array of size 6003 into shape (6003,3072) Any help on this, please? Thanks! python numpy Share Improve this question Follow...
