Error calling the interface of createSSDPriorBoxPlugin when prase my caffe model

using Jetson xavier and Jetpack 4.1
Hi,
[i]when i calling the interface of createSSDPriorBoxPlugin to parse my network model,the Segmentation problems offen occurs,the error log is:

[url]=========parse caffe model start==========
Warning: Flatten layer ignored. TensorRT implicitly flattens input to FullyConnected layers, but in other circumstances this will result in undefined behavior.

part of my code is simple as follows:

		std::cout << "==========createPlugin succ=========" << std::endl;
		
		return Inception3_conv_priorbox1_layer.get();

then,how do i deal with these Segmentation fault?

Hello,

to help us debug, can you please share a small repro that contains the code and model that demonstrate the seg fault you are seeing?

regards,
NVIDIA Enterprise Support

Hello,my code is similar to the sample of sampleFasterRCNN https://docs.nvidia.com/deeplearning/sdk/tensorrt-developer-guide/index.html#fasterrcnn_sample,for the reason of using the API of createSSDPriorBoxPlugin,we only create the class of IPluginFactoryExt as follows:

class PluginFactory : public nvinfer1::IPluginFactory,public nvcaffeparser1::IPluginFactoryExt

    // caffe parser plugin implementation
	bool isPlugin(const char* name) override { return isPluginExt(name); }
	
    bool isPluginExt(const char* name) override ;
    
    void destroyPlugin();

    void (*pluginDeleter)( nvinfer1::plugin::INvPlugin*) {[]( nvinfer1::plugin::INvPlugin* ptr) {ptr->destroy();}};

TRT doesn’t support flatten layer explicitly, but you can use reshape layer instead (like below).
And TRT 5.0 published caffe based SSD sample, you can get a complete reference there.

layer {
  name: "mbox_conf_flatten"
  type: "Reshape"
  bottom: "mbox_conf_softmax"
  top: "mbox_conf_flatten"
  reshape_param {
    shape {
      dim: 0
      dim: -1
      dim: 1
      dim: 1
    }
  }
}

Hello,
There is a new problem arose in the building trt engine,which link is in this websitehttps://devtalk.nvidia.com/default/topic/1045372/cuda-error-in-nchwtonchw/, please have a look, thank you !
