transpose
(x, axes=None)[source]¶ Permute the dimensions of an input variable without copy.
Parameters: - x (
Variable
ornumpy.ndarray
orcupy.ndarray
) – Input variable to be transposed. A \((s_1, s_2, ..., s_N)\) -shaped float array. - axes (tuple of ints) – By default, reverse the dimensions, otherwise permute the axes according to the values given.
Returns: Variable whose axes are permuted.
Return type: Example
>>> x = np.array([[[0, 1, 2], [3, 4, 5]]], np.float32) >>> x.shape (1, 2, 3) >>> y = F.transpose(x) # reverse the dimensions >>> y.shape (3, 2, 1) >>> y.data array([[[0.], [3.]], [[1.], [4.]], [[2.], [5.]]], dtype=float32) >>> y = F.transpose(x, axes=(1, 0, 2)) # swap 1st and 2nd axis >>> y.shape (2, 1, 3) >>> y.data array([[[0., 1., 2.]], [[3., 4., 5.]]], dtype=float32)
