Weights and Biases ci pypi codecov

Use W&B to build better models faster. Track and visualize all the pieces of your machine learning pipeline, from datasets to production models.

  • Quickly identify model regressions. Use W&B to visualize results in real time, all in a central dashboard.
  • Focus on the interesting ML. Spend less time manually tracking results in spreadsheets and text files.
  • Capture dataset versions with W&B Artifacts to identify how changing data affects your resulting models.
  • Reproduce any model, with saved code, hyperparameters, launch commands, input data, and resulting model weights.

πŸ“ˆ Track model and data pipeline hyperparameters

Set wandb.config once at the beginning of your script to save your hyperparameters, input settings (like dataset name or model type), and any other independent variables for your experiments. This is useful for analyzing your experiments and reproducing your work in the future. Setting configs also allows you to visualize the relationships between features of your model architecture or data pipeline and the model performance (as seen in the screenshot above).

wandb.init()
wandb.config.epochs = 4
wandb.config.batch_size = 32
wandb.config.learning_rate = 0.001
wandb.config.architecture = "resnet"

πŸ— Use your favorite framework

πŸ₯• Keras

In Keras, you can use our callback to automatically save all the metrics tracked in model.fit. To get you started here's a minimal example:

# Import W&B
import wandb
from wandb.keras import WandbCallback

# Step1: Initialize W&B run
wandb.init(project='project_name')

# 2. Save model inputs and hyperparameters
config = wandb.config
config.learning_rate = 0.01

# Model training code here ...

# Step 3: Add WandbCallback 
model.fit(X_train, y_train,  validation_data=(X_test, y_test),
          callbacks=[WandbCallback()])

πŸ”₯ PyTorch

W&B provides first class support for PyTorch. To automatically log gradients and store the network topology, you can call .watch and pass in your PyTorch model. Then use .log for anything else you want to track, like so:

import wandb

# 1. Start a new run
wandb.init(project="gpt-3")

# 2. Save model inputs and hyperparameters
config = wandb.config
config.dropout = 0.01

# 3. Log gradients and model parameters
wandb.watch(model)
for batch_idx, (data, target) in enumerate(train_loader):
  ...  
  if batch_idx % args.log_interval == 0:      
    # 4. Log metrics to visualize performance
    wandb.log({"loss": loss})

🌊 TensorFlow

The simplest way to log metrics in TensorFlow is by logging tf.summary with our TensorFlow logger:

import wandb

# 1. Start a W&B run
wandb.init(project='gpt3')

# 2. Save model inputs and hyperparameters
config = wandb.config
config.learning_rate = 0.01

# Model training here

# 3. Log metrics over time to visualize performance
with tf.Session() as sess:
  # ...
  wandb.tensorflow.log(tf.summary.merge_all())

πŸ’¨ fastai

Visualize, compare, and iterate on fastai models using Weights & Biases with the WandbCallback.

import wandb
from fastai2.callback.wandb import WandbCallback

# 1. Start a new run
wandb.init(project="gpt-3")

# 2. Automatically log model metrics
learn.fit(..., cbs=WandbCallback())

⚑️ PyTorch Lightning

Build scalable, structured, high-performance PyTorch models with Lightning and log them with W&B.

from pytorch_lightning.loggers import WandbLogger
from pytorch_lightning import Trainer

wandb_logger = WandbLogger(project="gpt-3")
trainer = Trainer(logger=wandb_logger)

πŸ€— HuggingFace

Just run a script using HuggingFace's Trainer in an environment where wandb is installed and we'll automatically log losses, evaluation metrics, model topology and gradients:

# 1. Install the wandb library
pip install wandb

# 2. Run a script that has the Trainer to automatically logs metrics, model topology and gradients
python run_glue.py \
 --model_name_or_path bert-base-uncased \
 --task_name MRPC \
 --data_dir $GLUE_DIR/$TASK_NAME \
 --do_train \
 --evaluate_during_training \
 --max_seq_length 128 \
 --per_gpu_train_batch_size 32 \
 --learning_rate 2e-5 \
 --num_train_epochs 3 \
 --output_dir /tmp/$TASK_NAME/ \
 --overwrite_output_dir \
 --logging_steps 50

🧹 Optimize hyperparameters with Sweeps

Use Weights & Biases Sweeps to automate hyperparameter optimization and explore the space of possible models.

Benefits of using W&B Sweeps

  • Quick to setup: With just a few lines of code you can run W&B sweeps.
  • Transparent: We cite all the algorithms we're using, and our code is open source.
  • Powerful: Our sweeps are completely customizable and configurable. You can launch a sweep across dozens of machines, and it's just as easy as starting a sweep on your laptop.

Weights & Biases

Common use cases

  • Explore: Efficiently sample the space of hyperparameter combinations to discover promising regions and build an intuition about your model.
  • Optimize: Use sweeps to find a set of hyperparameters with optimal performance.
  • K-fold cross validation: Here's a brief code example of k-fold cross validation with W&B Sweeps.

Visualize Sweeps results

The hyperparameter importance plot surfaces which hyperparameters were the best predictors of, and highly correlated to desirable values for your metrics.

Weights & Biases

Parallel coordinates plots map hyperparameter values to model metrics. They're useful for honing in on combinations of hyperparameters that led to the best model performance.

Weights & Biases

πŸ“œ Share insights with Reports

Reports let you organize visualizations, describe your findings, and share updates with collaborators.

Common use cases

  • Notes: Add a graph with a quick note to yourself.
  • Collaboration: Share findings with your colleagues.
  • Work log: Track what you've tried and plan next steps.

Explore reports in The Gallery β†’ | Read the Docs

Once you have experiments in W&B, you can visualize and document results in Reports with just a few clicks. Here's a quick demo video.

🏺 Version control datasets and models with Artifacts

Git and GitHub make code version control easy, but they're not optimized for tracking the other parts of the ML pipeline: datasets, models, and other large binary files.

W&B's Artifacts are. With just a few extra lines of code, you can start tracking you and your team's outputs, all directly linked to run.

Common use cases

  • Pipeline Management: Track and visualize the inputs and outputs of your runs as a graph
  • Don't Repeat Yourselfβ„’: Prevent the duplication of compute effort
  • Sharing Data in Teams: Collaborate on models and datasets without all the headaches

Testing

To run basic test use make test. More detailed information can be found at CONTRIBUTING.md.

We use circleci for CI.
