Track, compare, and visualize your ML models with 5 lines of code
Quickly and easily implement experiment logging by adding just a few lines to your script and start logging results. Our lightweight integration works with any Python script.
# Flexible integration for any Python script
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
wandb.log({"loss": loss})

Visualize and compare every experiment
See model metrics stream live into interactive graphs and tables. It is easy to see how your latest ML model is performing compared to previous experiments, no matter where you are training your models.
Quickly find and re-run previous model checkpoints
W&B’s experiment tracking saves everything you need to reproduce models later— the latest git commit, hyperparameters, model weights, and even sample test predictions. You can save experiment files and datasets directly to W&B or store pointers to your own storage.
import wandb
from transformers import DebertaV2ForQuestionAnswering
# 1. Create a wandb run
run = wandb.init(project=’turkish-qa’)
# 2. Connect to the model checkpoint you want on W&B
wandb_model = run.use_artifact(‘sally/turkish-qa/
deberta-v2:v5′)
# 3. Download the model files to a directory
model_dir = wandb_model.download()
# 4. Load your model
model = DebertaV2ForQuestionAnswering.from_pretrained(model_dir)
