MNIST


💻 Self-hosted

The community edition supports offline viewing of SwanLab dashboards.

Offline Experiment Tracking

Set the parameters logir and mode in swanlab.init to track experiments offline:

...

swanlab.init(
    logdir='./logs',
    mode='local',
)

...

  • The parameter mode is set to local, which disables synchronizing the experiment to the cloud.

  • The setting of the parameter logdir is optional, and it specifies the location for saving SwanLab log files (by default saved in the swanlog folder).

  • Log files will be created and updated during tracking of experiments, and launching offline dashboards will also be based on these log files.

Other parts are completely consistent with cloud usage.

Open Offline Board

Open the terminal and use the following command to open a SwanLab dashboard:

swanlab watch ./logs

After the operation is completed, SwanLab will provide you with a local URL link (default is http://127.0.0.1:5092).

Visit this link to view the experiment offline in the browser dashboard.

⚡️ PyTorch Lightning

Create an instance using SwanLabLogger and pass it into the logger parameter of Trainer to enable SwanLab to record training metrics.

from swanlab.integration.pytorch_lightning import SwanLabLogger
import importlib.util
import os
import pytorch_lightning as pl
from torch import nn, optim, utils
from torchvision.datasets import MNIST
from torchvision.transforms import ToTensor

encoder = nn.Sequential(nn.Linear(28 * 28, 128), nn.ReLU(), nn.Linear(128, 3))
decoder = nn.Sequential(nn.Linear(3, 128), nn.ReLU(), nn.Linear(128, 28 * 28))


class LitAutoEncoder(pl.LightningModule):
    def __init__(self, encoder, decoder):
        super().__init__()
        self.encoder = encoder
        self.decoder = decoder

    def training_step(self, batch, batch_idx):
        # training_step defines the train loop.
        # it is independent of forward
        x, y = batch
        x = x.view(x.size(0), -1)
        z = self.encoder(x)
        x_hat = self.decoder(z)
        loss = nn.functional.mse_loss(x_hat, x)
        # Logging to SwanLab (if installed) by default
        self.log("train_loss", loss)
        return loss

    def test_step(self, batch, batch_idx):
        # test_step defines the test loop.
        # it is independent of forward
        x, y = batch
        x = x.view(x.size(0), -1)
        z = self.encoder(x)
        x_hat = self.decoder(z)
        loss = nn.functional.mse_loss(x_hat, x)
        # Logging to SwanLab (if installed) by default
        self.log("test_loss", loss)
        return loss

    def configure_optimizers(self):
        optimizer = optim.Adam(self.parameters(), lr=1e-3)

swanlab_logger = SwanLabLogger(
    project="swanlab_example",
    experiment_name="example_experiment",
    cloud=False,
)

trainer = pl.Trainer(limit_train_batches=100, max_epochs=5, logger=swanlab_logger)

trainer.fit(model=autoencoder, train_dataloaders=train_loader, val_dataloaders=val_loader)
trainer.test(dataloaders=test_loader)
🤗HuggingFace Transformers

Create an instance using SwanLabCallback and pass it into the callbacks parameter of Trainer to enable SwanLab to record training metrics.

import evaluate
import numpy as np
import swanlab
from swanlab.integration.huggingface import SwanLabCallback
from datasets import load_dataset
from transformers import AutoModelForSequenceClassification, AutoTokenizer, Trainer, TrainingArguments


def tokenize_function(examples):
    return tokenizer(examples["text"], padding="max_length", truncation=True)


def compute_metrics(eval_pred):
    logits, labels = eval_pred
    predictions = np.argmax(logits, axis=-1)
    return metric.compute(predictions=predictions, references=labels)


dataset = load_dataset("yelp_review_full")

tokenizer = AutoTokenizer.from_pretrained("bert-base-cased")

tokenized_datasets = dataset.map(tokenize_function, batched=True)

small_train_dataset = tokenized_datasets["train"].shuffle(seed=42).select(range(1000))
small_eval_dataset = tokenized_datasets["test"].shuffle(seed=42).select(range(1000))

metric = evaluate.load("accuracy")

model = AutoModelForSequenceClassification.from_pretrained("bert-base-cased", num_labels=5)

training_args = TrainingArguments(
    output_dir="test_trainer",
    report_to="none",
    num_train_epochs=3,
    logging_steps=50,
)

swanlab_callback = SwanLabCallback(experiment_name="TransformersTest", cloud=False)

trainer = Trainer(
    model=model,
    args=training_args,
    train_dataset=small_train_dataset,
    eval_dataset=small_eval_dataset,
    compute_metrics=compute_metrics,
    callbacks=[swanlab_callback],
)

trainer.train()
MMEngine(MMDetection etc.)

Integrate SwanlabVisBackend into MMEngine to enable automatic logging of training metrics by SwanLab.

Add the following code snippet to your MM config file to start training:

custom_imports = dict(imports=["swanlab.integration.mmengine"], allow_failed_imports=False)

vis_backends = [
    dict(
        type="SwanlabVisBackend",
        save_dir="runs/swanlab",
        init_kwargs={
            "project": "swanlab-mmengine",
        },
    ),
]

visualizer = dict(
    type="Visualizer",
    vis_backends=vis_backends,
)
Ultralytics

Integrating SwanLab into Ultralytics is very simple; you can use the add_swanlab_callback function:

from ultralytics import YOLO
from swanlab.integration.ultralytics import add_swanlab_callback

model = YOLO("yolov8n.yaml")
model.load()

add_swanlab_callback(model)

model.train(
    data="./coco.yaml",
    epochs=50,
    imgsz=320,
)

🆚 Comparison with familiar tools

Tensorboard vs SwanLab

  • ☁️ Online Usage Support: With SwanLab, training experiments can be conveniently synchronized and saved in the cloud, allowing for remote monitoring of training progress, managing historical projects, sharing experiment links, sending real-time notification messages, and viewing experiments across multiple devices. In contrast, TensorBoard is an offline experiment tracking tool.

  • 👥 Collaborative Multi-user Environment: SwanLab facilitates easy management of multi-person training projects and sharing of experiment links for collaborative machine learning across teams. It also enables cross-space communication and discussion. On the other hand, TensorBoard is primarily designed for individual use, making it difficult to collaborate and share experiments with multiple users.

  • 💻 Persistent, Centralized Dashboard: Regardless of where you are training your models, be it on a local computer, a lab cluster, or on public cloud GPU instances, your results are logged to the same centralized dashboard. Using TensorBoard, on the other hand, requires spending time copying and managing TFEvent files from different machines.

  • 💪 More Powerful Tables: SwanLab tables allow you to view, search, and filter results from various experiments, making it easy to review thousands of model versions to find the best-performing models for different tasks. TensorBoard is not well-suited for large-scale projects.

Weights and Biases vs SwanLab

  • Weights and Biases is an online-only, proprietary MLOps platform.

  • Not only does SwanLab support online usage, but it also offers an open-source, free, and self-hosted version.
