r"""Swaps shapes and strides according to given pattern. Args: inp: input tensor. pattern: a list of integers including 0, 1, ... , ``ndim``-1, and any number of ``'x'`` char in dimensions where this tensor should be broadcasted. For examples:

(inp: Tensor, pattern: Iterable[int])

903 r"""Swaps shapes and strides according to given pattern.
904
905 Args:
906 inp: input tensor.
907 pattern: a list of integers including 0, 1, ... , ``ndim``-1,
908 and any number of ``'x'`` char in dimensions where this tensor should be broadcasted.
909 For examples:
910
911 * (``'x'``) -> make a 0d (scalar) into a 1d vector
912 * (0, 1) -> identity for 2d vectors
913 * (1, 0) -> inverts the first and second dimensions
914 * (``'x'``, 0) -> make a row out of a 1d vector (N to 1xN)
915 * (0, ``'x'``) -> make a column out of a 1d vector (N to Nx1)
916 * (2, 0, 1) -> AxBxC to CxAxB
917 * (0, ``'x'``, 1) -> AxB to Ax1xB
918 * (1, ``'x'``, 0) -> AxB to Bx1xA
919 * (1,) -> this removes dimensions 0. It must be a broadcastable dimension (1xA to A)
920
921 Returns:
922 output tensor.
923
924 Examples:
925 >>> import numpy as np
926 >>> x = Tensor(np.array([[1, 1], [0, 0]], dtype=np.int32))
927 >>> F.transpose(x, (1, 0))
928 Tensor([[1 0]
929 [1 0]], dtype=int32, device=xpux:0)
