%description
OpenNMT-tf also implements most of the techniques commonly used to train and evaluate sequence models, such as:
* automatic evaluation during the training
* multiple decoding strategy: greedy search, beam search, random sampling
* N-best rescoring
* gradient accumulation
* scheduled sampling
* checkpoint averaging
* ... and more!
*See the [documentation](https://opennmt.net/OpenNMT-tf/) to learn how to use these features.*
## Usage
OpenNMT-tf requires:
* Python 3.7 or above
* TensorFlow 2.6, 2.7, 2.8, 2.9, 2.10, or 2.11
We recommend installing it with `pip`:
```bash
pip install --upgrade pip
pip install OpenNMT-tf
```
*See the [documentation](https://opennmt.net/OpenNMT-tf/installation.html) for more information.*
### Command line
OpenNMT-tf comes with several command line utilities to prepare data, train, and evaluate models.
For all tasks involving a model execution, OpenNMT-tf uses a unique entrypoint: `onmt-main`. A typical OpenNMT-tf run consists of 3 elements:
* the **model** type
* the **parameters** described in a YAML file
* the **run** type such as `train`, `eval`, `infer`, `export`, `score`, `average_checkpoints`, or `update_vocab`
that are passed to the main script:
```
onmt-main --model_type <model> --config <config_file.yml> --auto_config <run_type> <run_options>
```
*For more information and examples on how to use OpenNMT-tf, please visit [our documentation](https://opennmt.net/OpenNMT-tf).*
### Library
OpenNMT-tf also exposes [well-defined and stable APIs](https://opennmt.net/OpenNMT-tf/package/overview.html), from high-level training utilities to low-level model layers and dataset transformations.
For example, the `Runner` class can be used to train and evaluate models with few lines of code:
```python
import opennmt
config = {
    "model_dir": "/data/wmt-ende/checkpoints/",
    "data": {
        "source_vocabulary": "/data/wmt-ende/joint-vocab.txt",
        "target_vocabulary": "/data/wmt-ende/joint-vocab.txt",
        "train_features_file": "/data/wmt-ende/train.en",
        "train_labels_file": "/data/wmt-ende/train.de",
        "eval_features_file": "/data/wmt-ende/valid.en",
        "eval_labels_file": "/data/wmt-ende/valid.de",
    }
}
model = opennmt.models.TransformerBase()
runner = opennmt.Runner(model, config, auto_config=True)
runner.train(num_devices=2, with_eval=True)
```
Here is another example using OpenNMT-tf to run efficient beam search with a self-attentional decoder:
```python
decoder = opennmt.decoders.SelfAttentionDecoder(num_layers=6, vocab_size=32000)
initial_state = decoder.initial_state(
    memory=memory, memory_sequence_length=memory_sequence_length
)
batch_size = tf.shape(memory)[0]
start_ids = tf.fill([batch_size], opennmt.START_OF_SENTENCE_ID)
decoding_result = decoder.dynamic_decode(
    target_embedding,
    start_ids=start_ids,
    initial_state=initial_state,
    decoding_strategy=opennmt.utils.BeamSearch(4),
)
```
More examples using OpenNMT-tf as a library can be found online:
* The directory [examples/library](https://github.com/OpenNMT/OpenNMT-tf/tree/master/examples/library) contains additional examples that use OpenNMT-tf as a library
* [nmt-wizard-docker](https://github.com/OpenNMT/nmt-wizard-docker) uses the high-level `opennmt.Runner` API to wrap OpenNMT-tf with a custom interface for training, translating, and serving
*For a complete overview of the APIs, see the [package documentation](https://opennmt.net/OpenNMT-tf/package/overview.html).*
