无法将 ONNX 模型解析为 TensorRT

Question

我正在使用 jetson nano

我尝试转换onnx模型https://github.com/onnx/models/tree/master/vision/body_analysis/emotion_ferplus

运行进入这个错误：

Answer 1

创建模型后使用此代码：

TRT_LOGGER = trt.Logger(trt.Logger.WARNING)
EXPLICIT_BATCH = 1 << (int)(trt.NetworkDefinitionCreationFlag.EXPLICIT_BATCH)
with trt.Builder(TRT_LOGGER) as builder, builder.create_network(EXPLICIT_BATCH) as network, trt.OnnxParser(network, TRT_LOGGER) as parser:
        with open("modelfile.onnx", 'rb') as model:
            if not parser.parse(model.read()):
                for error in range(parser.num_errors):
                    print(parser.get_error(error))
        engine = builder.build_cuda_engine(network)

您可以直接使用引擎，也可以保存以后再使用。

with open("output.engine", "wb") as f:
            f.write(engine.serialize())
