sampleSSD inference on jetson Nano in C++ error

Description

Hi,

I am trying to execute sampleSSD from /usr/src/tensorrt/sample/sampleSSD folder.
I have made the changes specified inthe README file as:
replaced type: Flatten -> Reshape
replaced flatten_param { … } -> reshape_param{…}

also replaced detect_out top: with keep_count.

But I am getting this error.

Can someone throw some suggestion to it to make it work.

Plugin layer output count is not equal to caffe output count
Segmentation fault (core dumped)

If i do not chnage anything in deploy.prototxt, I am gettin this error.

  • Full traceback of errors encountered

Could you please refer to below topic in case it helps:

Also, it seems share model has restricted access due to which i am not able to download it.

Thanks

no help from that link.

I think now the prototxt is edited properly. I missed to add detection_out layer with top: keep_count. No errors with flatten layers.

But I am getting a different error like this.
When i run ./sample_ssd :

[05/08/2020-12:59:20] [I] [TRT] Some tactics do not have sufficient workspace memory to run. Increasing workspace size may increase performance, please check verbose output.
[05/08/2020-13:02:02] [I] [TRT] Detected 1 inputs and 2 output network tensors.

Aborted (core dumped)

What could be the reason??
how to avoid it??

I think it might be due to this flatten layer.
Ca you try on latest TRT version after replacing flatten layer with reshape.

Thanks

Yes, I rectified it. Got it worked.

How to use same sampleSSD code to store the TRT engine and use it later without having to build it again for new images.??
Could you help me with that…

Please refer to below link and sample:


https://docs.nvidia.com/deeplearning/tensorrt/archives/tensorrt-710-ea/developer-guide/index.html#serial_model_c

Thanks

I am getting this error :

‘SampleSSDParams initializeSampleParams(const samplesCommon::Args&)’:
/home/ram/ALPR/OCR/sampleSSD/src/main.cpp:95:30: error: ‘const struct samplesCommon::Args’ has no member named ‘saveEngine’
params.saveEngine = args.saveEngine;
^~~~~~~~~~

What to do???

This is just a saveEngine file path argument that present the sample that i shared as reference:

You can either add that argument support in sampleSSD or replace it with filepath for trt engine.

Thanks

This is the code i am trying to execute. Could you please execute it with the changes??
i am getting like this when I run it.

This is the entire code of the sampleSSD:

Hi, I am not able to get the desired output. It is not saving the model.
Could you please sort it out…
Thank you

Hello,

I have tried serializing the engine and deserializing the engine.
Please check the script attached.

I am gettingsampleSSD.cpp (13.9 KB) bus error when I run for the first time.

It stores and deserialize the engine. but after that i get buss error. it does not go to infer part.

In second run with the stored engine.
I get segmentation error

this particular line executes several times and then segmentation error comes up.

Could you let me know what is the problem is all about??

I am getting compilation error while using the shared code. Could you please share the complete code along with Makefile that you are using in this case?

Also, could you please share complete error log?

Thanks

you can run it usign sample make files also.

I have chnaged only the Build method inside the class.

here is the code modifications to build method.

initLibNvInferPlugins(&gLogger.getTRTLogger(), "");


std::string engineName = std::string("ssd_Caffe_TRT_Engine") + ".buf";
bool engineExist = std::ifstream(engineName).good();

IRuntime* runtime = createInferRuntime(gLogger.getTRTLogger());
assert(runtime != nullptr);


if (engineExist)
{

	assert(mEngine != nullptr);
	
	gLogInfo << "*** deserializing" << std::endl;
  // Deserialize the engine
	std::string buffer = readBuffer(engineName);
	
	mEngine = std::shared_ptr<nvinfer1::ICudaEngine>(
			runtime->deserializeCudaEngine(buffer.data(), buffer.size(), nullptr), samplesCommon::InferDeleter());
	gLogInfo << "*** deserializing now:" << std::endl;
	runtime->destroy();
	gLogInfo << "*** executed" << std::endl;
	assert(mEngine != nullptr && "loaded afterwards");
   
	gLogInfo << "*** deserializing is done next -> infer" << std::endl;
    gLogInfo << "*** Final success deserializing from disk" << std::endl;
	return true;
	
}
else
{

	auto builder = SampleUniquePtr<nvinfer1::IBuilder>(nvinfer1::createInferBuilder(gLogger.getTRTLogger()));
	if (!builder)
	{
		return false;
	}

	auto network = SampleUniquePtr<nvinfer1::INetworkDefinition>(builder->createNetwork());
	if (!network)
	{
		return false;
	}

	auto config = SampleUniquePtr<nvinfer1::IBuilderConfig>(builder->createBuilderConfig());
	if (!config)
	{
		return false;
	}

	auto parser = SampleUniquePtr<nvcaffeparser1::ICaffeParser>(nvcaffeparser1::createCaffeParser());
	if (!parser)
	{
		return false;
	}
	
	auto constructed = constructNetwork(builder, network, config, parser);
	if (!constructed)
	{
		return false;
	}
	
	assert(network->getNbInputs() == 1);

	mInputDims = network->getInput(0)->getDimensions();
	assert(mInputDims.nbDims == 3);
	
	assert(trtModelStream != nullptr);

	writeBuffer(trtModelStream->data(), trtModelStream->size(), engineName);

	
   // Deserialize the engine
   // engine = runtime->deserializeCudaEngine(trtModelStream->data(), trtModelStream->size(), nullptr);
	gLogInfo << "*** deserializing starts" << std::endl;
	mEngine = std::shared_ptr<nvinfer1::ICudaEngine>(runtime->deserializeCudaEngine(trtModelStream->data(), trtModelStream->size(), nullptr), samplesCommon::InferDeleter());
	assert(mEngine != nullptr);
	gLogInfo << "*** deserializing success" << std::endl;
	trtModelStream->destroy();
	gLogInfo << "*** destroy success" << std::endl;
	runtime->destroy();
	if (!mEngine)
	{
		return false;
	}
	else
	{
		gLogInfo << "*** Final success creating to disk" << std::endl;
		return true;
	}
}

Add this to sampleSSD code and run it normally.

I am getting buss error at first run. But it saves the model to disk. (hope this is correctly saved.)

soon after the model is saved, bus error comes up and program ends.

Again when I run the code.

it reads the stored model and starts deserializing it.
that time I getting segmentation fault error.

I am using it with Cmake file not with make.

It works with make also. No problems with that

Here is the CMakeLists.txt contents.
edit it according to the file names.
