ERROR: Parameter check failed///ERROR: (Unnamed Layer* 81) [Concatenation]: all concat input tensors must have the same dimensions

Hello ,
When I use TRT to accelerate the onnx model ,the following error occured.
“”"
[TensorRT] ERROR: Parameter check failed at: …/builder/Layers.h::setPostPadding::351, condition: (postPadding.nbDims == 2 && allDimsGtEq(postPadding, 0) && allDimsLtEq(postPadding, 100000))
[TensorRT] ERROR: (Unnamed Layer* 81) [Concatenation]: all concat input tensors must have the same dimensions except on the concatenation axis
Completed parsing of ONNX file
Building an engine from file ./model/model.onnx; this may take a while…
[TensorRT] ERROR: Network must have at least one output
“”"
I am wondering about the ‘parameter check failed error’.
Any advice?Thanks.

In addition, the system environment is as follows:
python 3.6
tensorrt 5.1.6
pytorch 1.1.0
cuda 10.0
cudnn7.5.0

Hi,
For Concat operation, the number of dimensions of the input tensors must match, and all dimensions except axis must be equal.
Could you please verify the dimensions of each input values to concat operation?

Please refer to below links:

Thanks
