● 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...
tensor = torch.tensor([2,3,4], device = device) 1. 2. # 获取GPU后,将已经创建的tensor放到GPU上 device = torch.device("cuda") tensor = torch.tensor([1,2,3]).to(device) 1. 2. 3. # 在没有获取gpu的情况下,放到一个指定的gpu上(n为gpu号,默认为0) tensor = torch.tensor([3,4,...
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 ...
To concatenate list(tensors) Construct list(tensors) 创建一个包含张量的列表,以及2个张量如下: importtoroch a=[torch.tensor([[0.7,0.3], [0.2,0.8]]), torch.tensor([[0.5,0.9], [0.5,0.5]])] b=torch.tensor([[0.1,0.9], [0.3,0.7]]) ...
通过使用torch.tensor()函数,我们可以将Python中的列表快速转换为Torch张量。这个便捷的功能使我们能够更轻松地将数据准备好,以便在深度学习算法中使用。 张量(Tensor) 张量(Tensor)是深度学习中最基本的数据结构之一,类似于多维数组或矩阵。张量在PyTorch、TensorFlow等深度学习框架中被广泛使用,用于表示和...
