unbind¶

paddle.fluid.layers.nn. unbind ( input, axis=0 ) [source]

Removes a tensor dimension, then split the input tensor into multiple sub-Tensors. :param input: The input variable which is an N-D Tensor, data type being float32, float64, int32 or int64. :type input: Variable :param axis: A scalar with type int32|int64 shape [1]. The dimension along which to unbind. If \(axis < 0\), the

dimension to unbind along is \(rank(input) + axis\). Default is 0.
