triton.language.permute

triton.language.permute(input, *dims, _semantic=None)

Permutes the dimensions of a tensor.

Parameters:

• input (Block) – The input tensor.

• dims – The desired ordering of dimensions. For example, (2, 1, 0) reverses the order dims in a 3D tensor.

dims can be passed as a tuple or as individual parameters:

# These are equivalent
permute(x, (2, 1, 0))
permute(x, 2, 1, 0)

trans() is equivalent to this function, except when dims is empty, it tries to swap the last two axes.

This function can also be called as a member function on tensor, as x.permute(...) instead of permute(x, ...).
