TensorRT ONNX error


I am trying to import FasterRCNN from ONNX to TensorRT and I recieved a parsing error in the resize operation.


TensorRT Version:
GPU Type: GeForce RTX 2070 Super
Nvidia Driver Version: 441.87
CUDA Version: 10.2
CUDNN Version:
Operating System + Version: Windows 10
Python Version (if applicable): -
TensorFlow Version (if applicable): -
PyTorch Version (if applicable): -
Baremetal or Container (if container which image + tag): -
ONNX version: 1.5
Opset version: 10

Steps To Reproduce

I am trying to import Faster RCNN model from ONNX to TensorRT. When I parse the model I get the following error while reading an operation:

UNKNOWN: ModelImporter.cpp:107: Parsing node: 415 [Resize]
UNKNOWN: ModelImporter.cpp:123: Searching for input: 388
UNKNOWN: ModelImporter.cpp:123: Searching for input: 415
UNKNOWN: ModelImporter.cpp:129: 415 [Resize] inputs: [388 -> (-1, 256, -1, -1)], [415 -> (4)],
While parsing node number 413 [Resize -> "416"]:
--- Begin node ---
input: "388"
input: "415"
output: "416"
name: "415"
op_type: "Resize"
attribute {
  name: "mode"
  s: "nearest"
  type: STRING

--- End node ---
ERROR: builtin_op_importers.cpp:2412 In function importResize:
[8] Assertion failed: scales.is_weights() && "Resize scales must be an initializer!"

The code snippet is:
// 1) Create a network definition, import the model

    // 1.1.- Create the inference builder
    IBuilder* builder = createInferBuilder(gLogger);

    // Create the network definition
    const auto explicitBatch = 1U << static_cast<uint32_t>(nvinfer1::NetworkDefinitionCreationFlag::kEXPLICIT_BATCH);
    INetworkDefinition* network = builder->createNetworkV2(explicitBatch);

    // 1.2.- Create onnx parser
    nvonnxparser::IParser* parser = nvonnxparser::createParser(*network, gLogger);

    // 1.3.- Parse the model
    size_t verbosity{4};
    parser->parseFromFile(DEPLOY_FILE, verbosity);

    if (!parser->parse(DEPLOY_FILE, verbosity))
        std::cout << "Failed to parse onnx file." << std::endl;
        return nullptr;

I found similar issues in github like this. I do not know if I understood it well, so the nearest resize operation is not supported?
How could I solve this issue? Does upgrading to TensorRT 7.1 would help?

Thank you for your time

Can you try solution suggested in below link:

Opset11 model above with TRT7 + OSS components.

Oh sorry, its true. The answer was in front of me, my fault.

Thank you

Changing opset to 11 and trying to troubleshoot with your suggestions in previous post I recieved the following assertion of TensorRT;

Looking at the neural network graph visualizer I got 4 resize layers that have the same issue:

The model checker from onnx did not output any message (I suppose this is good). Reading through the previous github issue, I wil try to run the mentioned onnx simplifier and see how it goes.

I am facing exact same issue, any update so far ?
