## Installation

0. DeepPavlov supports `Linux`, `Windows 10+` (through WSL/WSL2), `MacOS` (Big Sur+) platforms, `Python 3.6`, `3.7`, `3.8`, `3.9` and `3.10`.
    Depending on the model used, you may need from 4 to 16 GB RAM.

1. Create and activate a virtual environment:
    * `Linux`
    ```
    python -m venv env
    source ./env/bin/activate
    ```
2. Install the package inside the environment:
    ```
    pip install deeppavlov
    ```

## QuickStart

There is a bunch of great pre-trained NLP models in DeepPavlov. Each model is
determined by its config file.

List of models is available on
[the doc page](http://docs.deeppavlov.ai/en/master/features/overview.html) in
the `deeppavlov.configs` (Python):

```python
from deeppavlov import configs
```

When you're decided on the model (+ config file), there are two ways to train,
evaluate and infer it:

* via [Command line interface (CLI)](https://github.com/deeppavlov/DeepPavlov/blob/master/#command-line-interface-cli) and
* via [Python](https://github.com/deeppavlov/DeepPavlov/blob/master/#python).

#### GPU requirements

By default, DeepPavlov installs models requirements from PyPI. PyTorch from PyPI could not support your device CUDA
capability. To run supported DeepPavlov models on GPU you should have [CUDA](https://developer.nvidia.com/cuda-toolkit)
compatible with used GPU and [PyTorch version](https://github.com/deeppavlov/DeepPavlov/blob/master/deeppavlov/requirements/pytorch.txt) required by DeepPavlov models.
See [docs](https://docs.deeppavlov.ai/en/master/intro/quick_start.html#using-gpu) for details.
GPU with Pascal or newer architecture and 4+ GB VRAM is recommended.

### Command line interface (CLI)

To get predictions from a model interactively through CLI, run

```bash
python -m deeppavlov interact <config_path> [-d] [-i]
```

* `-d` downloads required data - pretrained model files and embeddings (optional).
* `-i` installs model requirements (optional).

You can train it in the same simple way:

```bash
python -m deeppavlov train <config_path> [-d] [-i]
```

Dataset will be downloaded regardless of whether there was `-d` flag or not.

To train on your own data you need to modify dataset reader path in the
[train config doc](http://docs.deeppavlov.ai/en/master/intro/config_description.html#train-config).
The data format is specified in the corresponding model doc page. 

There are even more actions you can perform with configs:

```bash
python -m deeppavlov <action> <config_path> [-d] [-i]
```

* `<action>` can be
    * `install` to install model requirements (same as `-i`),
    * `download` to download model's data (same as `-d`),
    * `train` to train the model on the data specified in the config file,
    * `evaluate` to calculate metrics on the same dataset,
    * `interact` to interact via CLI,
    * `riseapi` to run a REST API server (see
    [doc](http://docs.deeppavlov.ai/en/master/integrations/rest_api.html)),
    * `predict` to get prediction for samples from *stdin* or from
      *<file_path>* if `-f <file_path>` is specified.
* `<config_path>` specifies path (or name) of model's config file
* `-d` downloads required data
* `-i` installs model requirements


### Python

To get predictions from a model interactively through Python, run

```python
from deeppavlov import build_model

model = build_model(<config_path>, install=True, download=True)

# get predictions for 'input_text1', 'input_text2'
model(['input_text1', 'input_text2'])
```
where
* `install=True` installs model requirements (optional),
* `download=True` downloads required data from web - pretrained model files and embeddings (optional),
* `<config_path>` is model name (e.g. `'ner_ontonotes_bert_mult'`), path to the chosen model's config file (e.g.
  `"deeppavlov/configs/ner/ner_ontonotes_bert_mult.json"`),  or `deeppavlov.configs` attribute (e.g.
  `deeppavlov.configs.ner.ner_ontonotes_bert_mult` without quotation marks).

You can train it in the same simple way:

```python
from deeppavlov import train_model 

model = train_model(<config_path>, install=True, download=True)
```

To train on your own data you need to modify dataset reader path in the
[train config doc](http://docs.deeppavlov.ai/en/master/intro/config_description.html#train-config).
The data format is specified in the corresponding model doc page. 

You can also calculate metrics on the dataset specified in your config file:

```python
from deeppavlov import evaluate_model 

model = evaluate_model(<config_path>, install=True, download=True)
```

DeepPavlov also [allows](https://docs.deeppavlov.ai/en/master/intro/python.html) to build a model from components for
inference using Python.
