WebFeb 17, 2024 · To shift the bits of array elements of a 2D array to the left, use the numpy.left_shift () method in Python Numpy. Bits are shifted to the left by appending x2 0s at the right of x1. Since the internal representation of numbers is in binary format, this operation is equivalent to multiplying x1 by 2**x2. The x1 is the Input values. Webtorch.roll¶ torch. roll (input, shifts, dims = None) → Tensor ¶ Roll the tensor input along the given dimension(s).
