onnx converted to trt problem

when i converted onnx model to trt, always getting a reshape error， error are as follows： 10_27_16_38_[TRT: ERR][graphShapeAnalyzer.cpp::nvinfer1::builder::`anonymous-namespace’::ShapeNodeRemover::analyzeShapes::1285] Error Code 4: Miscellaneous (IShuffleLayer Reshape_170: reshape changes volume.

Reshaping [14763] to [1].)

when i remove anomaly_score item in output ,such as: anomaly_map = self.anomaly_map_generator(patch_scores) output = (anomaly_map)

and the error changed, 10_27_15_11_[TRT: ERR][shuffleNode.cpp::nvinfer1::builder::ShuffleNode::symbolicExecute::387] Error Code 4: Internal Error (Reshape_183: IShuffleLayer applied to shape tensor must have 0 or 1 reshape dimensions: dimensions were [-1,2]) 10_27_15_11_[TRT: ERR]ModelImporter.cpp:773: While parsing node number 193 [Pad -> “521”]: 10_27_15_11_[TRT: ERR]ModelImporter.cpp:774: — Begin node — 10_27_15_11_[TRT: ERR]ModelImporter.cpp:775: input: “486” input: “520” output: “521” name: “Pad_193” op_type: “Pad” attribute { name: “mode” s: “reflect” type: STRING }

finally, i find it’s problem always appear inBelow the ConstantOfShape node。

what should i do, for this problem?

，I found and solved this problem, It is a problem due to padding operation, replace this operation.

Hi，Can you explain how to solve this problem，Please show the code, thank you！
