- paddle.fluid.contrib.layers.nn. partial_concat ( input, start_index=0, length=- 1 )
Partial Concat This OP concatenates the inputs according to the start index and length. This OP exists in contrib, which means that it is not shown to the public. Only 2-D Tensor or LodTensor input is supported. Slice and concat can only be performed along the second dimension.
Given: x = [[0, 1, 2], [3, 4, 5]] y = [[6, 7 ,8], [9, 10, 11]] output = partial_concat([x, y], start_index=0, length=2) we get: output = [[0, 1, 6, 7], [3, 4, 9, 10]]
input (list) – List of input Tensors with data type float32, float64, int32, int64.
start_index (int32) – The start index of each instance for partial concatenation. Default is 0.
length (int32) – The length of each instance for partial concatenation. Default is -1. Negative values for all elements after start_index.
A Tensor with the same data type as input’s.
- Return type
