We also want to automatically compute gradients of functions on tensors. In Trax we want numpy operations to run very fast, making use of GPUs and TPUs to accelerate them.
TIME TRAKS MERLIN PROJECT HOW TO
You should take a look at the numpy guide if you don't know how to operate on tensors: Trax also uses the numpy API for that. The basic units flowing through Trax models are tensors - multi-dimensional arrays, sometimes also known as numpy arrays, due to the most widely used package for tensor operations - numpy. You can learn here how Trax works, how to create new models and how to train them on your own data. It runs without any changes on CPUs, GPUs and TPUs. Or as a binary from the shell, which can be more convenient for training large models. You can use Trax either as a library from your own python scripts and notebooks Trax has bindings to a large number of deep learning datasets, including New models like the Reformer and new RL algorithms like AWR. It is also actively used for research and includes Trax includes basic models (like ResNet, LSTM, Transformer) and RL algorithms detokenize( tokenized_translation,Įs ist schön, heute neue Dinge zu lernen! # De-tokenize, tokenized_translation = tokenized_translation # Remove batch and EOS.

We welcome contributions to Trax! We welcome PRs with code for new models and layers as well as improvements to our code and documentation. Walkthrough: how Trax works, how to make new models and train on your own data.Features and resources: API docs, where to talk to us, how to open an issue and more.Run a pre-trained Transformer: create a translator in a few lines of code.This notebook ( run it in colab) shows how to use Trax and where you can find more information. It is actively used and maintained in the Google Brain team. Trax is an end-to-end library for deep learning that focuses on clear code and speed.
