Concat - version 4

This page documents version 4 of operator Concat. See Concat for the latest version (since version 13).

• Domain: ai.onnx

• Since version: 4

Concatenate a list of tensors into a single tensor

Inputs

• inputs (T): List of tensors for concatenation

Outputs

• concat_result (T): Concatenated tensor

Type Constraints

• T: Constrain output types to any tensor type. Allowed types: tensor(bool), tensor(complex128), tensor(complex64), tensor(double), tensor(float), tensor(float16), tensor(int16), tensor(int32), tensor(int64), tensor(int8), tensor(string), tensor(uint16), tensor(uint32), tensor(uint64), tensor(uint8).
