The TensorFlow tutorials are written as Jupyter notebooks and run directly in Google Colab—a hosted notebook environment that requires no setup. At the top of each tutorialyou'll see a Run in Google Colab button. Click the button to open the notebook and run the code yourself.

For beginners

The best place to start is with the user-friendly Keras sequential API. Build models by plugging together building blocks. After these tutorialsread the Keras guide.
This "HelloWorld!" notebook shows the Keras Sequential API and model.fit.
This notebook collection demonstrates basic machine learning tasks using Keras.
These tutorials use tf.data to load various data formats and build input pipelines.

For experts

The Keras functional and subclassing APIs provide a define-by-run interface for customization and advanced research. Build your modelthen write the forward and backward pass. Create custom layersactivationsand training loops.
This "HelloWorld!" notebook uses the Keras subclassing API and a custom training loop.
This notebook collection shows how to build custom layers and training loops in TensorFlow.
Distribute your model training across multiple GPUsmultiple machines or TPUs.
The Advanced section has many instructive notebooks examplesincluding Neural machine translationTransformersand CycleGAN.
