[TensorRT] Failed to load engine file converted by torch2trt

Hi,

We recommend you to please run on the latest TensorRT version 8.2 EA.
Please make sure your model is valid, were you able to generate onnx model ?

Following similar issue may be helpful.

[TensorRT] ERROR: ../rtSafe/coreReadArchive.cpp (31) - Serialization Error in verifyHeader: 0 (Magic tag does not match)

My problem was due to 2 issues : Wrong inputs to th model in terms of input size. Loading multiple runtimes at once in the memory. You should load the runtime only once and deserialize multiple models in that runtime only instead of loading different runtime for every model. I was able to resolve the issue by fixing these issues. Maybe you can try these !

Thank you.
