megengine在cuda平台推理时候出现core dumped

[g1050]

环境

1.系统环境：Ubuntu 18.04.6 LTS
2.MegEngine版本：master分支3b1a1d0 commit编译
3.python版本：Python 3.6.9

复现步骤

1.代码采用注释掉的std::shared_ptr<Network> network = std::make_shared<Network>(config, network_io);方式加载模型
2.编译

cd test_megengine/src/cplusplus/
bash build.sh

3.执行
./bin/lite_infer ../model/lenet.mge ../image/handwrittern-digit.png

请提供关键的代码片段便于追查问题

// cuda配置
lite::Config config{LiteDeviceType::LITE_CUDA};
NetworkIO network_io;
IO device_input{"data",false};
network_io.inputs.push_back(device_input);

//加载模型
// std::shared_ptr<Network> network = std::make_shared<Network>(config, network_io);
std::shared_ptr<Network> network = std::make_shared<Network>();
network->load_model(model_path);

请提供完整的日志及报错信息
