Concatenates tensors along one dimension.

values A list of at least 2 Tensor objects with the same type. List of N Tensors to concatenate. Their ranks and types must match, and their sizes must match in all dimensions except concat_dim.
axis A Tensor. Must be one of the following types: int32, int64. 0-D. The dimension along which to concatenate. Must be in the range [-rank(values), rank(values)).
name A name for the operation (optional).

A Tensor. Has the same type as values.
