Your problem

When I run the code: doInference_slowfast(*context_action, data_fast, data_slow, proposals, prob_data, 1); It will raise a segmentation fault. But when I comment it, it shows: [07/12/2022-13:59:02] [E] [TRT] 1: [pluginV2Runner.cpp::load::290] Error Code 1: Serialization (Serialization assertion creator failed.Cannot deserialize plugin since corresponding IPluginCreator not found in Plugin Registry) [07/12/2022-13:59:02] [E] [TRT] 4: [runtime.cpp::deserializeCudaEngine::50] Error Code 4: Internal Error (Engine deserialization failed.)

Here is my IPluginCreator: ITensor* inputTensors_roi[] = {proposals, avgpool->getOutput(0)}; auto creator2 = getPluginRegistry()->getPluginCreator("RoiAlign", "1"); PluginField pField2[1]; int *s2 = new int[4]; s2[0] = 8; s2[1] = 0; s2[2] = MAX_OUTPUT_COUNT; s2[3] = avgpool->getOutput(0)->getDimensions().d[0]; pField2[0].data = s2; pField2[0].length = 4; pField2[0].type = PluginFieldType::kINT32; pField2[0].name = "factor"; PluginFieldCollection pluginData2; pluginData2.nbFields = 1; pluginData2.fields = pField2; IPluginV2 *pluginObj2 = creator2->createPlugin("RoIAlign", &pluginData2); auto roiAlignLayer = network->addPluginV2(inputTensors_roi, 2, *pluginObj2);

#define PLUGIN_NAME "RoiAlign" #define PLUGIN_VERSION "1"

class API RoiAlignPluginCreator : public IPluginCreator{

const char *getPluginName() const TRT_NOEXCEPT override {
    return PLUGIN_NAME;
}

const char *getPluginVersion() const TRT_NOEXCEPT override {
    return PLUGIN_VERSION;
}
IPluginV2Ext *createPlugin(const char *name, const PluginFieldCollection *fc) TRT_NOEXCEPT override {
    
    assert(fc->nbFields == 1);
    int *p_netinfo = (int*)(fc->fields[0].data);
    int pooler_resolution = p_netinfo[0];
    int sampling_ratio = p_netinfo[1];
    int num_proposals = p_netinfo[2];
    int out_channels = p_netinfo[3];
    float spatial_scale = 1.0/16.0;
    return new RoiAlignPlugin(pooler_resolution, spatial_scale, sampling_ratio, num_proposals, out_channels);

}
