● TensorRT 支持在这些 Tensor Core 上注册和执行一些深度学习模型的稀疏层。● Torch-TensorRT 扩展了对卷积层和全连接层的支持。 示例:图像分类的吞吐量比较 在本文中,您将通过名为 EfficientNet 的图像分类模型执行推理,并计算导出模型在使用 PyTorch、TorchScript JIT 和 Torch-TensorRT 优化时的吞吐量。有关详细...

torch.fx是Pytorch 1.8出来的一套工具或者说一个库,是做python-to-python code transformation,大意就是可以把pytorch中的python前向代码转换为你想要的样子,官方介绍如下: We apply this principle in torch.fx, a program capture and transformation library forPyTorchwritten entirely in Python and optimized for ...

Nodes that describe tensor computations are converted to one or more TensorRT layers. The remaining nodes stay in TorchScripting, forming a hybrid graph that is returned as a standard TorchScript module. Figure 3. Mapping Torch’s ops to TensorRT ops for the fully connected layer ...
