I failed to build the engine using the methods in this blog.

Dear @user123137,
May I know the Jetpack version? We have ResNet50.onnx model as part of TRT sample. Did you check using it directly?

Jetpack’s version is 4.5.1.Whether it is a low version?
I used Onnx.checker.check_model method to check it and it has no problem.

Dear @user123137,
Could you test with Jetpack 5.1

Thank you for your answer.
Can Jetpack 4.5.1 and L4T 32.5.1 be upgraded with package management tools instead of SD card and Sdkmanager?

Dear @user123137,
You should use sdkmanager to flash jetpack
