用法:
mxnet.ndarray.op.broadcast_axis(data=None, axis=_Null, size=_Null, out=None, name=None, **kwargs)
out:- 此函数的输出。
NDArray 或 NDArray 列表
参数:
返回:
返回类型:
在特定轴上广播输入数组。
在大小为 1 的轴上允许广播,例如从
(2,1,3,1)
到(2,8,3,9)
。元素将在广播轴上复制。broadcast_axes
是函数broadcast_axis
的别名。例子:
// given x of shape (1,2,1) x = [[[ 1.], [ 2.]]] // broadcast x on on axis 2 broadcast_axis(x, axis=2, size=3) = [[[ 1., 1., 1.], [ 2., 2., 2.]]] // broadcast x on on axes 0 and 2 broadcast_axis(x, axis=(0,2), size=(2,3)) = [[[ 1., 1., 1.], [ 2., 2., 2.]], [[ 1., 1., 1.], [ 2., 2., 2.]]]
