Loading engine file with Python

[elisabetta496]

Hi,
I have successfully used your tools to create a tensorrt engine and I'm trying to load the engine file with Python but the plugin is not found.

I'm using:

with open(engineFile, "rb") as f, trt.Runtime(G_LOGGER) as runtime: engine = runtime.deserialize_cuda_engine(f.read())

and getting the following error:

[TensorRT] ERROR: INVALID_ARGUMENT: getPluginCreator could not find plugin L2Norm_Helper_TRT version 1 [TensorRT] ERROR: safeDeserializationUtils.cpp (259) - Serialization Error in load: 0 (Cannot deserialize plugin since corresponding IPluginCreator not found in Plugin Registry) [TensorRT] ERROR: INVALID_STATE: std::exception [TensorRT] ERROR: INVALID_CONFIG: Deserialize the cuda engine failed.

Could you help me solving this issue?
I don't understand how to use the Python bindings you talked about in a previous topic. In which file I have to insert them?
Thanks

I also have the same error while loading the engine file in Python. In C++ I compile and build engine file Successfully. While loading in Python It gives me the same error. How can I use this custom layers in Python?

@Neel125
Could you share the details, how you build it in C++
Did you use TRT 6 version or TRT 8.
