HI，

我按照你的流程安装环境后，报了以下问题，我的环境python3.8, tensorRT版本nvidia_tensorrt-8.4.1.5-cp38-none-linux_x86_64.whl

python trt.py [07/31/2022-16:12:30] [TRT] [E] 1: [stdArchiveReader.cpp::StdArchiveReader::35] Error Code 1: Serialization (Serialization assertion safeVersionRead == safeSerializationVersion failed.Version tag does not match. Note: Current Version: 0, Serialized Engine Version: 43) [07/31/2022-16:12:30] [TRT] [E] 4: [runtime.cpp::deserializeCudaEngine::50] Error Code 4: Internal Error (Engine deserialization failed.)

Serialization assertion safeVersionRead == safeSerializationVersion failed.Version tag does not match

序列化和反序列的版本应该一致

@jia0511 @Xintianbyz @LeonNerd 前期由于V7仓库文档的混乱，导致大家对相关的实现有误解， 最近更新了代码提供了更简单的端到端实现， examples.ipynb 给出了详细的例子
