 I wrote this project to get familiar with tensorrt API, and also to share and learn from the community.
 
-TensorRTx has a brother project [Pytorchx](https://github.com/wang-xinyu/pytorchx). All the models are implemented in pytorch first, and export a weights file xxx.wts, and then use tensorrt to load weights, define network and do inference.
