PyTorch Build 中的三个选项从左往右代表稳定版,先行版,长期支持版,一般选择第一个即可。 Package表示使用什么包管理工具安装,依据本机的Python环境选择。 Compute Platform:表示安装GPU版还是CPU版本,只支持nvidia的显卡,如果本机没有可用显卡,就安装CPU版本,否则选择CUDA安装。注意如果要安装GPU版本,还需要安装对应的G...
set_property(TARGET example-app PROPERTY CXX_STANDARD 14) 至此,就可以运行以下命令从example-app/文件夹中构建应用程序啦: mkdir build cd build cmake -DCMAKE_PREFIX_PATH=/path/to/libtorch .. cmake --build . --config Release 其中/path/to/libtorch是之前下载后的libtorch文件夹所在的路径。这一步...

In this example, write a Dockerfile to create a custom image on a Linux x86_64 server running Ubuntu 18.04. Objective: Build and install container images of the following software and use the images and CPUs/GPUs for training on ModelArts. ...
In this example we will use the nn package to define our model as before, but we will optimize the model using the Adam algorithm provided by the optim package: # Code in file nn/two_layer_net_optim.py import torch import torch.nn as nn import torch.optim as optim from torch.autograd...
