I get the following ERROR with tenrorRT 6.5 in Driveworks when parsing an onnx file; same model succeeds with tensorRT 7.2 on server.

…
While parsing node number 168 [Resize]:
ERROR: ModelImporter.cpp:125 In function parseGraph:

Error: DW_FILE_INVALID: DNNGenerator: Unable to parse ONNX model.

Is this a known issue?

The onnx model was generated with pytorch; here are the version details:

Hi, @user3705
Please try if running an onnx file generated with opset 10 has the issue. Thanks.

Thanks! After setting the opset version to 10, the model completes to run.
