fix(autoware_tensorrt_common): invalid engine model file

[ralwing]

Signed-off-by: Grzegorz Głowacki gglowacki@autonomous-systems.pl

Description

After a CUDA update and the creation of a new .engine model, the module can print an error like this:

Error code: 1, Description: IRuntime::deserializeCudaEngine: Error Code 1: Serialization (Serialization assertion stdVersionRead == kSERIALIZATION_VERSION failed. Version tag does not match. Note: Current Version: 237, Serialized Engine Version: 236)

This error stops the node from loading, and it doesn't resolve itself. This PR fixes this by deleting the incompatible .engine file. The file will then be automatically regenerated when the node starts again. This makes software updates easier for production."

Effects on system behavior

Removes the incompatible engine model.

Hi @ralwing,

Thanks for your contribution!

I think it would be better to handle mismatch of TensorRT version used to build engine. This higher level mismatch would also fall into exception. Can you check if this PR does work for you?

If not, we can proceed with your PR. However, your code looks like a copy of someone else work, licensed under GPLv3. If this is the case, I think it is not a problem, but you might need to provide source of copied code and change the license of package.
