Prerequisites
PyTorch v2.9+ and
torchvisionRay Tune (
ray[tune]) v2.52.1+GPU(s) are optional, but recommended for faster training
Ray, a project of the PyTorch Foundation, is an open source unified framework for scaling AI and Python applications. It helps run distributed jobs by handling the complexity of distributed computing. Ray Tune is a library built on Ray for hyperparameter tuning that enables you to scale a hyperparameter sweep from your machine to a large cluster with no code changes.
This tutorial adapts the PyTorch tutorial for training a CIFAR10 classifier to run multi-GPU hyperparameter sweeps with Ray Tune.
Setup#
To run this tutorial, install the following dependencies:
pip install "ray[tune]" torchvision
Then start with the imports:
from functools import partial
import os
import tempfile
from pathlib import Path
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
# New: imports for Ray Tune
import ray
from ray import tune
from ray.tune import Checkpoint
from ray.tune.schedulers import ASHAScheduler
Data loading#
Wrap the data loaders in a constructor function. In this tutorial, a global data directory is passed to the function to enable reusing the dataset across different trials. In a cluster environment, you can use shared storage, such as network file systems, to prevent each node from downloading the data separately.
def load_data(data_dir="./data"):
# Mean and standard deviation of the CIFAR10 training subset.
transform = transforms.Compose(
[transforms.ToTensor(), transforms.Normalize((0.4914, 0.48216, 0.44653), (0.2022, 0.19932, 0.20086))]
)
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
Model architecture#
This tutorial searches for the best sizes for the fully connected layers
and the learning rate. To enable this, the Net class exposes the
layer sizes l1 and l2 as configurable parameters that Ray Tune
can search over:
class Net(nn.Module):
def __init__(self, l1=120, l2=84):
super().__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 = torch.flatten(x, 1) # flatten all dimensions except batch
x = F.relu(self.fc1(x))
x = F.relu(self.fc2(x))
x = self.fc3(x)
return x
Define the search space#
Next, define the hyperparameters to tune and how Ray Tune samples them.
Ray Tune offers a variety of search space
distributions
to suit different parameter types: loguniform, uniform,
choice, randint, grid, and more. You can also express
complex dependencies between parameters with conditional search
spaces
or sample from arbitrary functions.
Here is the search space for this tutorial:
config = {
"l1": tune.choice([2**i for i in range(9)]),
"l2": tune.choice([2**i for i in range(9)]),
"lr": tune.loguniform(1e-4, 1e-1),
"batch_size": tune.choice([2, 4, 8, 16]),
}
The tune.choice() accepts a list of values that are uniformly
sampled from. In this example, the l1 and l2 parameter values
are powers of 2 between 1 and 256, and the learning rate samples on a
log scale between 0.0001 and 0.1. Sampling on a log scale enables
exploration across a range of magnitudes on a relative scale, rather
than an absolute scale.
Training function#
Ray Tune requires a training function that accepts a configuration dictionary and runs the main training loop. As Ray Tune runs different trials, it updates the configuration dictionary for each trial.
Here is the full training function, followed by explanations of the key Ray Tune integration points:
def train_cifar(config, data_dir=None):
net = Net(config["l1"], config["l2"])
device = config["device"]
net = net.to(device)
if torch.cuda.device_count() > 1:
net = nn.DataParallel(net)
criterion = nn.CrossEntropyLoss()
optimizer = optim.SGD(net.parameters(), lr=config["lr"], momentum=0.9)
# Load checkpoint if resuming training
checkpoint = tune.get_checkpoint()
if checkpoint:
with checkpoint.as_directory() as checkpoint_dir:
checkpoint_path = Path(checkpoint_dir) / "checkpoint.pt"
checkpoint_state = torch.load(checkpoint_path)
start_epoch = checkpoint_state["epoch"]
net.load_state_dict(checkpoint_state["net_state_dict"])
optimizer.load_state_dict(checkpoint_state["optimizer_state_dict"])
else:
start_epoch = 0
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(start_epoch, 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
# Save checkpoint and report metrics
checkpoint_data = {
"epoch": epoch,
"net_state_dict": net.state_dict(),
"optimizer_state_dict": optimizer.state_dict(),
}
with tempfile.TemporaryDirectory() as checkpoint_dir:
checkpoint_path = Path(checkpoint_dir) / "checkpoint.pt"
torch.save(checkpoint_data, checkpoint_path)
checkpoint = Checkpoint.from_directory(checkpoint_dir)
tune.report(
{"loss": val_loss / val_steps, "accuracy": correct / total},
checkpoint=checkpoint,
)
print("Finished Training")
Key integration points#
Using hyperparameters from the configuration dictionary#
Ray Tune updates the config dictionary with the hyperparameters for
each trial. In this example, the model architecture and optimizer
receive the hyperparameters from the config dictionary:
Reporting metrics and saving checkpoints#
The most important integration is communicating with Ray Tune. Ray Tune uses the validation metrics to determine the best hyperparameter configuration and to stop underperforming trials early, saving resources.
Checkpointing enables you to later load the trained models, resume hyperparameter searches, and provides fault tolerance. It’s also required for some Ray Tune schedulers like Population Based Training that pause and resume trials during the search.
This code from the training function loads model and optimizer state at the start if a checkpoint exists:
checkpoint = tune.get_checkpoint()
if checkpoint:
with checkpoint.as_directory() as checkpoint_dir:
checkpoint_path = Path(checkpoint_dir) / "checkpoint.pt"
checkpoint_state = torch.load(checkpoint_path)
start_epoch = checkpoint_state["epoch"]
net.load_state_dict(checkpoint_state["net_state_dict"])
optimizer.load_state_dict(checkpoint_state["optimizer_state_dict"])
At the end of each epoch, save a checkpoint and report the validation metrics:
checkpoint_data = {
"epoch": epoch,
"net_state_dict": net.state_dict(),
"optimizer_state_dict": optimizer.state_dict(),
}
with tempfile.TemporaryDirectory() as checkpoint_dir:
checkpoint_path = Path(checkpoint_dir) / "checkpoint.pt"
torch.save(checkpoint_data, checkpoint_path)
checkpoint = Checkpoint.from_directory(checkpoint_dir)
tune.report(
{"loss": val_loss / val_steps, "accuracy": correct / total},
checkpoint=checkpoint,
)
Ray Tune checkpointing supports local file systems, cloud storage, and distributed file systems. For more information, see the Ray Tune storage documentation.
Multi-GPU support#
Image classification models can be greatly accelerated by using GPUs.
The training function supports multi-GPU training by wrapping the model
in nn.DataParallel:
if torch.cuda.device_count() > 1:
net = nn.DataParallel(net)
This training function supports training on CPUs, a single GPU, multiple GPUs, or multiple nodes without code changes. Ray Tune automatically distributes the trials across the nodes according to the available resources. Ray Tune also supports fractional GPUs so that one GPU can be shared among multiple trials, provided that the models, optimizers, and data batches fit into the GPU memory.
Validation split#
The original CIFAR10 dataset only has train and test subsets. This is sufficient for training a single model, however for hyperparameter tuning a validation subset is required. The training function creates a validation subset by reserving 20% of the training subset. The test subset is used to evaluate the best model’s generalization error after the search completes.
Evaluation function#
After finding the optimal hyperparameters, test the model on a held-out test set to estimate the generalization error:
def test_accuracy(net, device="cpu", data_dir=None):
_trainset, testset = load_data(data_dir)
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:
image_batch, labels = data
image_batch, labels = image_batch.to(device), labels.to(device)
outputs = net(image_batch)
_, predicted = torch.max(outputs.data, 1)
total += labels.size(0)
correct += (predicted == labels).sum().item()
return correct / total
Configure and run Ray Tune#
With the training and evaluation functions defined, configure Ray Tune to run the hyperparameter search.
Scheduler for early stopping#
Ray Tune provides schedulers to improve the efficiency of the
hyperparameter search by detecting underperforming trials and stopping
them early. The ASHAScheduler uses the Asynchronous Successive
Halving Algorithm (ASHA) to aggressively terminate low-performing
trials:
scheduler = ASHAScheduler(
max_t=max_num_epochs,
grace_period=1,
reduction_factor=2,
)
Ray Tune also provides advanced search algorithms to smartly pick the next set of hyperparameters based on previous results, instead of relying only on random or grid search. Examples include Optuna and BayesOpt.
Resource allocation#
Tell Ray Tune what resources to allocate for each trial by passing a
resources dictionary to tune.with_resources:
tune.with_resources(
partial(train_cifar, data_dir=data_dir),
resources={"cpu": cpus_per_trial, "gpu": gpus_per_trial}
)
Ray Tune automatically manages the placement of these trials and ensures that the trials run in isolation, so you don’t need to manually assign GPUs to processes.
For example, if you are running this experiment on a cluster of 20
machines, each with 8 GPUs, you can set gpus_per_trial = 0.5 to
schedule two concurrent trials per GPU. This configuration runs 320
trials in parallel across the cluster.
Note
To run this tutorial without GPUs, set gpus_per_trial=0
and expect significantly longer runtimes.
To avoid long runtimes during development, start with a small number of trials and epochs.
Creating the Tuner#
The Ray Tune API is modular and composable. Pass your configuration to
the tune.Tuner class to create a tuner object, then run
tuner.fit() to start training:
tuner = tune.Tuner(
tune.with_resources(
partial(train_cifar, data_dir=data_dir),
resources={"cpu": cpus_per_trial, "gpu": gpus_per_trial}
),
tune_config=tune.TuneConfig(
metric="loss",
mode="min",
scheduler=scheduler,
num_samples=num_trials,
),
param_space=config,
)
results = tuner.fit()
After training completes, retrieve the best performing trial, load its checkpoint, and evaluate on the test set.
Putting it all together#
def main(num_trials=10, max_num_epochs=10, gpus_per_trial=0, cpus_per_trial=2):
print("Starting hyperparameter tuning.")
ray.init(include_dashboard=False)

Observability#
Monitoring is critical when running large-scale experiments. Ray provides a dashboard that lets you view the status of your trials, check cluster resource use, and inspect logs in real time.
For debugging, Ray also offers distributed debugging tools that let you attach a debugger to running trials across the cluster.
Conclusion#
In this tutorial, you learned how to tune the hyperparameters of a
PyTorch model using Ray Tune. You saw how to integrate Ray Tune into
your PyTorch training loop, define a search space for your
hyperparameters, use an efficient scheduler like ASHAScheduler to
terminate low-performing trials early, save checkpoints and report
metrics to Ray Tune, and run the hyperparameter search and analyze the
results.
Ray Tune makes it straightforward to scale your experiments from a single machine to a large cluster, helping you find the best model configuration efficiently.
