Texar-PyTorch is a toolkit aiming to support a broad set of machine learning, especially natural language processing and text generation tasks. Texar provides a library of easy-to-use ML modules and functionalities for composing whatever models and algorithms. The tool is designed for both researchers and practitioners for fast prototyping and experimentation. Texar-PyTorch was originally developed and is actively contributed by Petuum and CMU in collaboration with other institutes. A mirror of this repository is maintained by Petuum Open Source.
Texar-PyTorch integrates many of the best features of TensorFlow into PyTorch, delivering highly usable and customizable modules superior to PyTorch native ones.
Key Features
- Two Versions, (Mostly) Same Interfaces. Texar-PyTorch (this repo) and Texar-TF have mostly the same interfaces. Both further combine the best design of TF and PyTorch:
- Interfaces and variable sharing in PyTorch convention
- Excellent factorization and rich functionalities in TF convention.
- Versatile to support broad needs:
- data processing, model architectures, loss functions, training and inference algorithms, evaluation, ...
- encoder(s) to decoder(s), sequential- and self-attentions, memory, hierarchical models, classifiers, ...
- maximum likelihood learning, reinforcement learning, adversarial learning, probabilistic modeling, ...
- Fully Customizable at multiple abstraction level -- both novice-friendly and expert-friendly.
- Free to plug in whatever external modules, since Texar is fully compatible with the native PyTorch APIs.
- Modularized for maximal re-use and clean APIs, based on principled decomposition of Learning-Inference-Model Architecture.
- Rich Pre-trained Models, Rich Usage with Uniform Interfaces. BERT, GPT2, XLNet, etc, for encoding, classification, generation, and composing complex models with other Texar components!
- Clean, detailed documentation and rich examples.


Library API Example
A code example that builds and trains a Conditional GPT2 model (e.g., for machine translation and text summarization):
```python import texar.torch as tx from texar.torch.run import *
(1) Modeling
class ConditionalGPT2Model(nn.Module): """An encoder-decoder model with GPT-2 as the decoder.""" def init(self, vocabsize): super().init() # Use hyperparameter dict for model configuration self.embedder = tx.modules.WordEmbedder(vocabsize, hparams=embhparams) self.encoder = tx.modules.TransformerEncoder(hparams=enchparams) self.decoder = tx.modules.GPT2Decoder("gpt2-small") # With pre-trained weights
def getdecoderoutput(self, batch, train=True): """Perform model inference, i.e., decoding.""" encstates = self.encoder(inputs=self.embedder(batch['sourcetextids']), sequencelength=batch['sourcelength']) if train: # Teacher-forcing decoding at training time return self.decoder( inputs=batch['targettextids'], sequencelength=batch['targetlength'] - 1, memory=encstates, memorysequencelength=batch['sourcelength']) else: # Beam search decoding at prediction time starttokens = torch.fulllike(batch['sourcetextids'][:, 0], BOS) return self.decoder( beamwidth=5, starttokens=starttokens, memory=encstates, memorysequencelength=batch['source_length'])
def forward(self, batch): """Compute training loss.""" outputs = self.getdecoderoutput(batch) loss = tx.losses.sequencesparsesoftmaxcrossentropy( # Sequence loss labels=batch['targettextids'][:, 1:], logits=outputs.logits, sequencelength=batch['target_length'] - 1) # Automatic masking return {"loss": loss}
def predict(self, batch): """Compute model predictions.""" sequence, _ = self.getdecoderoutput(batch, train=False) return {"gentext_ids": sequence}
(2) Data
Create dataset splits using built-in data loaders
datasets = {split: tx.data.PairedTextData(hparams=data_hparams[split]) for split in ["train", "valid", "test"]}
model = ConditionalGPT2Model(datasets["train"].target_vocab.size)
(3) Training
Manage the train-eval loop with the Executor API
executor = Executor( model=model, datasets=datasets, optimizer={"type": torch.optim.Adam, "kwargs": {"lr": 5e-4}}, stoptrainingon=cond.epoch(20), logevery=cond.iteration(100), validateevery=cond.epoch(1), trainmetric=("loss", metric.RunningAverage(10, predname="loss")), validmetric=metric.BLEU(predname="gentextids", labelname="targettextids"), saveevery=cond.validation(better=True), checkpointdir="outputs/savedmodels/") executor.train() executor.test(datasets["test"]) ``` Many more examples are available here.
Installation
Texar-PyTorch requires:
python == 3.6or3.7torch >= 1.0.0. Please follow the official instructions to install the appropriate version.
After torch is installed, install Texar from PyPI:
bash
pip install texar-pytorch
To use cutting-edge features or develop locally, install from source:
git clone https://github.com/asyml/texar-pytorch.git
cd texar-pytorch
pip install .
To use tensorboard support with Executor, please install tensorboardX with the following command
commandline
pip install tensorboardX
