使用 Ray Tune 的超参数调整

原文:https://pytorch.org/tutorials/beginner/hyperparameter_tuning_tutorial.html

超参数调整可以使平均模型与高精度模型有所不同。 通常,选择不同的学习率或更改网络层大小等简单的事情可能会对模型表现产生巨大影响。

幸运的是,有一些工具可以帮助您找到最佳的参数组合。 Ray Tune 是用于分布式超参数调整的行业标准工具。 Ray Tune 包含最新的超参数搜索算法,与 TensorBoard 和其他分析库集成,并通过 Ray 的分布式机器学习引擎本地支持分布式训练。

在本教程中,我们将向您展示如何将 Ray Tune 集成到 PyTorch 训练工作流程中。 我们将扩展 PyTorch 文档的本教程,以训练 CIFAR10 图像分类器。

如您所见,我们只需要添加一些细微的修改即可。 特别是,我们需要

  1. 在函数中包装数据加载和训练,
  2. 使一些网络参数可配置,
  3. 添加检查点(可选),
  4. 并定义用于模型调整的搜索空间

要运行本教程,请确保已安装以下包:

  • ray[tune]:分布式超参数调整库
  • torchvision:用于数据转换器

设置/导入

让我们从导入开始:

from functools import partial
import numpy as np
import os
import torch
import torch.nn as nn
import torch.nn.functional as F
import torch.optim as optim
from torch.utils.data import random_split
import torchvision
import torchvision.transforms as transforms
from ray import tune
from ray.tune import CLIReporter
from ray.tune.schedulers import ASHAScheduler

建立 PyTorch 模型需要大多数导入产品。 Ray Tune 仅最后三个导入。

数据加载器

我们将数据加载器包装在它们自己的函数中,并传递一个全局数据目录。 这样,我们可以在不同的试验之间共享数据目录。

def load_data(data_dir="./data"):
    transform = transforms.Compose([
        transforms.ToTensor(),
        transforms.Normalize((0.5, 0.5, 0.5), (0.5, 0.5, 0.5))
    ])

    trainset = torchvision.datasets.CIFAR10(
        root=data_dir, train=True, download=True, transform=transform)

    testset = torchvision.datasets.CIFAR10(
        root=data_dir, train=False, download=True, transform=transform)

    return trainset, testset

可配置的神经网络

我们只能调整那些可配置的参数。 在此示例中,我们可以指定全连接层的层大小:

class Net(nn.Module):
    def __init__(self, l1=120, l2=84):
        super(Net, self).__init__()
        self.conv1 = nn.Conv2d(3, 6, 5)
        self.pool = nn.MaxPool2d(2, 2)
        self.conv2 = nn.Conv2d(6, 16, 5)
        self.fc1 = nn.Linear(16 * 5 * 5, l1)
        self.fc2 = nn.Linear(l1, l2)
        self.fc3 = nn.Linear(l2, 10)

    def forward(self, x):
        x = self.pool(F.relu(self.conv1(x)))
        x = self.pool(F.relu(self.conv2(x)))
        x = x.view(-1, 16 * 5 * 5)
        x = F.relu(self.fc1(x))
        x = F.relu(self.fc2(x))
        x = self.fc3(x)
        return x

训练函数

现在变得有趣了,因为我们对 PyTorch 文档中的示例进行了一些更改。

我们将训练脚本包装在函数train_cifar(config, checkpoint_dir=None, data_dir=None)中。 可以猜到,config参数将接收我们要训练的超参数。 checkpoint_dir参数用于还原检查点。 data_dir指定了我们加载和存储数据的目录,因此多次运行可以共享同一数据源。

net = Net(config["l1"], config["l2"])

if checkpoint_dir:
    model_state, optimizer_state = torch.load(
        os.path.join(checkpoint_dir, "checkpoint"))
    net.load_state_dict(model_state)
    optimizer.load_state_dict(optimizer_state)

优化器的学习率也可以配置:

optimizer = optim.SGD(net.parameters(), lr=config["lr"], momentum=0.9)

我们还将训练数据分为训练和验证子集。 因此,我们训练了 80% 的数据,并计算了其余 20% 的验证损失。 我们遍历训练和测试集的批量大小也是可配置的。

通过DataParallel添加(多)GPU 支持

图像分类主要受益于 GPU。 幸运的是,我们可以继续在 Ray Tune 中使用 PyTorch 的抽象。 因此,我们可以将模型包装在nn.DataParallel中,以支持在多个 GPU 上进行数据并行训练:

device = "cpu"
if torch.cuda.is_available():
    device = "cuda:0"
    if torch.cuda.device_count() > 1:
        net = nn.DataParallel(net)
net.to(device)

通过使用device变量,我们可以确保在没有 GPU 的情况下训练也能正常进行。 PyTorch 要求我们将数据显式发送到 GPU 内存,如下所示:

for i, data in enumerate(trainloader, 0):
    inputs, labels = data
    inputs, labels = inputs.to(device), labels.to(device)

该代码现在支持在 CPU,单个 GPU 和多个 GPU 上进行训练。 值得注意的是,Ray 还支持分数 GPU ,因此我们可以在试验之间共享 GPU,只要模型仍适合 GPU 内存即可。 我们稍后再讲。

与 Ray Tune 交流

最有趣的部分是与 Ray Tune 的交流:

with tune.checkpoint_dir(epoch) as checkpoint_dir:
    path = os.path.join(checkpoint_dir, "checkpoint")
    torch.save((net.state_dict(), optimizer.state_dict()), path)

tune.report(loss=(val_loss / val_steps), accuracy=correct / total)

在这里,我们首先保存一个检查点,然后将一些指标报告给 Ray Tune。 具体来说,我们将验证损失和准确率发送回 Ray Tune。 然后,Ray Tune 可以使用这些指标来决定哪种超参数配置可以带来最佳结果。 这些指标还可用于尽早停止效果不佳的试验,以避免浪费资源进行试验。

保存检查点是可选的,但是,如果我们想使用高级调度器,例如基于总体的训练,则有必要。 另外,通过保存检查点,我们可以稍后加载经过训练的模型并在测试集上对其进行验证。

完整的训练函数

完整的代码示例如下所示:

def train_cifar(config, checkpoint_dir=None, data_dir=None):
    net = Net(config["l1"], config["l2"])

    device = "cpu"
    if torch.cuda.is_available():
        device = "cuda:0"
        if torch.cuda.device_count() > 1:
            net = nn.DataParallel(net)
    net.to(device)

    criterion = nn.CrossEntropyLoss()
    optimizer = optim.SGD(net.parameters(), lr=config["lr"], momentum=0.9)

    if checkpoint_dir:
        model_state, optimizer_state = torch.load(
            os.path.join(checkpoint_dir, "checkpoint"))
        net.load_state_dict(model_state)
        optimizer.load_state_dict(optimizer_state)

    trainset, testset = load_data(data_dir)

    test_abs = int(len(trainset) * 0.8)
    train_subset, val_subset = random_split(
        trainset, [test_abs, len(trainset) - test_abs])

    trainloader = torch.utils.data.DataLoader(
        train_subset,
        batch_size=int(config["batch_size"]),
        shuffle=True,
        num_workers=8)
    valloader = torch.utils.data.DataLoader(
        val_subset,
        batch_size=int(config["batch_size"]),
        shuffle=True,
        num_workers=8)

    for epoch in range(10):  # loop over the dataset multiple times
        running_loss = 0.0
        epoch_steps = 0
        for i, data in enumerate(trainloader, 0):
            # get the inputs; data is a list of [inputs, labels]
            inputs, labels = data
            inputs, labels = inputs.to(device), labels.to(device)

            # zero the parameter gradients
            optimizer.zero_grad()

            # forward + backward + optimize
            outputs = net(inputs)
            loss = criterion(outputs, labels)
            loss.backward()
            optimizer.step()

            # print statistics
            running_loss += loss.item()
            epoch_steps += 1
            if i % 2000 == 1999:  # print every 2000 mini-batches
                print("[%d, %5d] loss: %.3f" % (epoch + 1, i + 1,
                                                running_loss / epoch_steps))
                running_loss = 0.0

        # Validation loss
        val_loss = 0.0
        val_steps = 0
        total = 0
        correct = 0
        for i, data in enumerate(valloader, 0):
            with torch.no_grad():
                inputs, labels = data
                inputs, labels = inputs.to(device), labels.to(device)

                outputs = net(inputs)
                _, predicted = torch.max(outputs.data, 1)
                total += labels.size(0)
                correct += (predicted == labels).sum().item()

                loss = criterion(outputs, labels)
                val_loss += loss.cpu().numpy()
                val_steps += 1

        with tune.checkpoint_dir(epoch) as checkpoint_dir:
            path = os.path.join(checkpoint_dir, "checkpoint")
            torch.save((net.state_dict(), optimizer.state_dict()), path)

        tune.report(loss=(val_loss / val_steps), accuracy=correct / total)
    print("Finished Training")

如您所见,大多数代码直接来自原始示例。

测试集准确率

通常,机器学习模型的表现是在保持测试集上使用尚未用于训练模型的数据进行测试的。 我们还将其包装在一个函数中:

def test_accuracy(net, device="cpu"):
    trainset, testset = load_data()

    testloader = torch.utils.data.DataLoader(
        testset, batch_size=4, shuffle=False, num_workers=2)

    correct = 0
    total = 0
    with torch.no_grad():
        for data in testloader:
            images, labels = data
            images, labels = images.to(device), labels.to(device)
            outputs = net(images)
            _, predicted = torch.max(outputs.data, 1)
            total += labels.size(0)
            correct += (predicted == labels).sum().item()

    return correct / total

该函数还需要一个device参数,因此我们可以在 GPU 上进行测试集验证。

配置搜索空间

最后,我们需要定义 Ray Tune 的搜索空间。 这是一个例子:

config = {
    "l1": tune.sample_from(lambda _: 2**np.random.randint(2, 9)),
    "l2": tune.sample_from(lambda _: 2**np.random.randint(2, 9)),
    "lr": tune.loguniform(1e-4, 1e-1),
    "batch_size": tune.choice([2, 4, 8, 16])
}

tune.sample_from()函数使您可以定义自己的采样方法以获得超参数。 在此示例中,l1l2参数应为 4 到 256 之间的 2 的幂,因此应为 4、8、16、32、64、128 或 256。lr(学习率)应在 0.0001 和 0.1 之间均匀采样。 最后,批量大小可以在 2、4、8 和 16 之间选择。

现在,在每次试用中,Ray Tune 都会从这些搜索空间中随机抽取参数组合。 然后它将并行训练许多模型,并在其中找到表现最佳的模型。 我们还使用ASHAScheduler,它将尽早终止效果不佳的测试。

我们用functools.partial包装train_cifar函数以设置常量data_dir参数。 我们还可以告诉 Ray Tune 每个审判应提供哪些资源:

gpus_per_trial = 2
# ...
result = tune.run(
    partial(train_cifar, data_dir=data_dir),
    resources_per_trial={"cpu": 8, "gpu": gpus_per_trial},
    config=config,
    num_samples=num_samples,
    scheduler=scheduler,
    progress_reporter=reporter,
    checkpoint_at_end=True)

您可以指定 CPU 的数量,例如增加 PyTorch DataLoader实例的num_workers。 在每次试用中,选定数量的 GPU 对 PyTorch 都是可见的。 试用版无法访问未要求使用 GPU 的 GPU,因此您不必担心使用同一组资源进行两次试用。

在这里,我们还可以指定分数 GPU,因此gpus_per_trial=0.5之类的东西完全有效。 然后,试用版将彼此共享 GPU。 您只需要确保模型仍然适合 GPU 内存即可。

训练完模型后,我们将找到表现最好的模型,并从检查点文件中加载训练后的网络。 然后,我们获得测试仪的准确率,并通过打印报告一切。

完整的main函数如下:

def main(num_samples=10, max_num_epochs=10, gpus_per_trial=2):
    data_dir = os.path.abspath("./data")
    load_data(data_dir)
    config = {
        "l1": tune.sample_from(lambda _: 2 ** np.random.randint(2, 9)),
        "l2": tune.sample_from(lambda _: 2 ** np.random.randint(2, 9)),
        "lr": tune.loguniform(1e-4, 1e-1),
        "batch_size": tune.choice([2, 4, 8, 16])
    }
    scheduler = ASHAScheduler(
        metric="loss",
        mode="min",
        max_t=max_num_epochs,
        grace_period=1,
        reduction_factor=2)
    reporter = CLIReporter(
        # parameter_columns=["l1", "l2", "lr", "batch_size"],
        metric_columns=["loss", "accuracy", "training_iteration"])
    result = tune.run(
        partial(train_cifar, data_dir=data_dir),
        resources_per_trial={"cpu": 2, "gpu": gpus_per_trial},
        config=config,
        num_samples=num_samples,
        scheduler=scheduler,
        progress_reporter=reporter)

    best_trial = result.get_best_trial("loss", "min", "last")
    print("Best trial config: {}".format(best_trial.config))
    print("Best trial final validation loss: {}".format(
        best_trial.last_result["loss"]))
    print("Best trial final validation accuracy: {}".format(
        best_trial.last_result["accuracy"]))

    best_trained_model = Net(best_trial.config["l1"], best_trial.config["l2"])
    device = "cpu"
    if torch.cuda.is_available():
        device = "cuda:0"
        if gpus_per_trial > 1:
            best_trained_model = nn.DataParallel(best_trained_model)
    best_trained_model.to(device)

    best_checkpoint_dir = best_trial.checkpoint.value
    model_state, optimizer_state = torch.load(os.path.join(
        best_checkpoint_dir, "checkpoint"))
    best_trained_model.load_state_dict(model_state)

    test_acc = test_accuracy(best_trained_model, device)
    print("Best trial test set accuracy: {}".format(test_acc))

if __name__ == "__main__":
    # You can change the number of GPUs per trial here:
    main(num_samples=10, max_num_epochs=10, gpus_per_trial=0)
