String Slicing Python also allows a form of indexing syntax that extracts substrings from a string, known as string slicing. WebStride is the jump necessary to go from one element to the next one in the specified dimension dim. A tuple of all strides is returned when no argument is passed in. …

WebIndexing and Slicing. To get a value at a particular index of this array, say a[5], the stride is multiplied by the index value to get the number of bytes to move from the start of the buffer to read itemsize-many bytes: Just like Python lists, arrays can be sliced. For example, a[::2] returns every other value from the array: WebRoughly speaking, this op extracts a slice of size (end-begin)/stride from the given input_ tensor. Starting at the location specified by begin the slice continues by adding stride to the index until all dimensions are not less than end.
