- paddle. chunk ( x, chunks, axis=0, name=None )
Split the input tensor into multiple sub-Tensors.
x (Tensor) – A N-D Tensor. The data type is bool, float16, float32, float64, int32 or int64.
chunks (int) – The number of tensor to be split along the certain axis.
axis (int|Tensor, optional) – The axis along which to split, it can be a scalar with type
Tensorwith shape  and data type
int64. If :math::axis < 0, the axis to split along is \(rank(x) + axis\). Default is 0.
name (str, optional) – The default value is None. Normally there is no need for user to set this property. For more information, please refer to Name .
