快速入门¶
这是一份关于如何编写简单应用程序并开始在本地和远程集群上启动分布式作业的自包含指南。
安装¶
我们需要做的第一件事是安装 TorchX python 包，其中包括 CLI 和库。
# install torchx with all dependencies
$ pip install torchx[dev]
有关安装的更多信息，请参阅 README。
[1]:
%%sh
torchx --help
usage: torchx [-h] [--log_level LOG_LEVEL] [--version]
{builtins,cancel,configure,describe,list,log,run,runopts,status,tracker}
...
torchx CLI
optional arguments:
-h, --help show this help message and exit
--log_level LOG_LEVEL
Python logging log level
--version show program's version number and exit
sub-commands:
Use the following commands to run operations, e.g.: torchx run ${JOB_NAME}
{builtins,cancel,configure,describe,list,log,run,runopts,status,tracker}
世界您好¶
让我们从编写一个简单的 “Hello World” python 应用程序开始。这只是一个普通的 python 程序，可以包含您想要的任何内容。
注意
此示例使用 Jupyter Notebook 创建本地文件以用于示例目的。在正常使用情况下，您可以将这些文件作为独立文件。%%writefile
[2]:
%%writefile my_app.py
import sys
print(f"Hello, {sys.argv[1]}!")
Overwriting my_app.py
发射¶
我们可以通过以下方式执行我们的应用程序。调度程序相对于当前目录执行应用程序。torchx runlocal_cwd
为此，我们将使用组件：utils.python
[3]:
%%sh

该组件接受脚本名称，任何额外的参数都将传递给脚本本身。

我们可以通过调度器运行完全相同的应用程序。此调度程序会将本地工作区打包为指定映像之上的层。这提供了与基于容器的远程调度器非常相似的环境。local_docker
注意
这需要安装 Docker，并且在 Google Colab 等环境中不起作用。请参阅 Docker 安装说明：https://docs.docker.com/get-docker/

TorchX 默认使用 ghcr.io/pytorch/torchx Docker 容器镜像，其中包含 PyTorch 库、TorchX 和相关依赖项。
分散式¶
TorchX 的组件使用 TorchElastic 来管理 worker。这意味着您可以在我们支持的所有调度程序上开箱即用地启动多工作线程和多主机作业。dist.ddp

让我们创建一个稍微有趣的应用程序来利用 TorchX 分布式支持。

dist.init_process_group(backend="gloo")
print(f"I am worker {dist.get_rank()} of {dist.get_world_size()}!")
a = torch.tensor([dist.get_rank()])
dist.all_reduce(a)
print(f"all_reduce output = {a}")

让我们启动一个小型作业，每个节点有 2 个节点和 2 个工作进程：

工作区 / 修补¶
对于每个调度器，都有一个 .for 和 ，它使用当前工作目录。对于基于容器的调度程序，例如 ，它使用 docker 容器。imagelocal_cwdslurmlocal_dockerkubernetesaws_batch
为了在本地和远程作业之间提供相同的环境，TorchX CLI 使用工作区根据每个计划程序自动修补远程作业的映像。
当您通过它启动任务时，它会将当前目录叠加在提供的图像之上，以便您的代码在启动的任务中可用。torchx run
对于基于调度程序的调度程序，您需要一个本地 docker 守护程序来构建镜像并将其推送到远程 docker 存储库。docker
.torchxconfig¶
调度程序的参数可以通过命令行标志指定，也可以通过文件按调度程序指定。torchx run -s <scheduler> -c <args>.torchxconfig
[9]:
%%writefile .torchxconfig
[kubernetes]
queue=torchx
image_repo=<your docker image repository>
[slurm]
partition=torchx
Overwriting .torchxconfig
远程调度程序¶
TorchX 支持大量的调度器。没有看到您的？请求它！
远程调度程序的运行方式与本地调度程序完全相同。相同的 local run 命令在 remote 上开箱即用。
$ torchx run --scheduler slurm dist.ddp -j 2x2 --script dist_app.py
$ torchx run --scheduler kubernetes dist.ddp -j 2x2 --script dist_app.py
$ torchx run --scheduler aws_batch dist.ddp -j 2x2 --script dist_app.py
$ torchx run --scheduler ray dist.ddp -j 2x2 --script dist_app.py
根据调度程序，可能会有一些额外的配置参数，以便 TorchX 知道在何处运行作业并上传构建的镜像。这些可以通过 或在文件中设置。-c.torchxconfig
