# FastPDN

FastPolDeepNer is a model designed for easy use, training and configuration. The forerunner of this project is [PolDeepNer2](https://gitlab.clarin-pl.eu/information-extraction/poldeepner2). The model implements a pipeline consisting of data processing and training using: hydra, pytorch, pytorch-lightning, transformers.

## How to use

Here is how to use this model to get the Named Entities in text:

```python
from transformers import pipeline
ner = pipeline('ner', model='clarin-pl/FastPDN', aggregation_strategy='simple')

text = "Nazywam się Jan Kowalski i mieszkam we Wrocławiu."
ner_results = ner(text)
for output in ner_results:
    print(output)

{'entity_group': 'nam_liv_person', 'score': 0.9996054, 'word': 'Jan Kowalski', 'start': 12, 'end': 24}
{'entity_group': 'nam_loc_gpe_city', 'score': 0.998931, 'word': 'Wrocławiu', 'start': 39, 'end': 48}
```

Here is how to use this model to get the logits for every token in text:

```python
from transformers import AutoTokenizer, AutoModelForTokenClassification

tokenizer = AutoTokenizer.from_pretrained("clarin-pl/FastPDN")
model = AutoModelForTokenClassification.from_pretrained("clarin-pl/FastPDN")

text = "Nazywam się Jan Kowalski i mieszkam we Wrocławiu."
encoded_input = tokenizer(text, return_tensors='pt')
output = model(**encoded_input)
```

### Developing

Model pipeline consists of 2 steps:

- Data processing
- Training
- (optional) Share model to Hugginface Hub

#### Config

This project use hydra configuration. Every configuration used in this module
is placed in `.yaml` files in `config` directory.

This directory has structure:

- prepare_data.yaml - main configuration for the data processing stage
- train.yaml - main configuration for the training stage
- share_mode.yaml - main configuraion for sharing model to Huggingface Hub
- callbacks - contains callbacks for pytorch_lightning trainer
  - default.yaml
  - early_stopping.yaml
  - learning_rate_monitor.yaml
  - model_checkpoint.yaml
  - rich_progress_bar.yaml
- datamodule - contains pytorch_lightning datamodule configuration
  - pdn.yaml
- experiment - contains all the configurations of executed experiments
- hydra - hydra configuration files
- loggers - contains loggers for trainer
  - csv.yaml
  - many_loggers.yaml
  - tensorboards.yaml
  - wandb.yaml
- model - contains model architecture hyperparameters
  - default.yaml
  - distiluse.yaml
  - custom_classification_head.yaml
  - multilabel.yaml
- paths - contains paths for IO
- prepare_data - contains configuration for data processing stage
  - cen_n82
  - default
- trainer - contains trainer configurations
  - default.yaml
  - cpu.yaml
  - gpu.yaml

#### Training

1. Install requirements with poetry

```
poetry install
```

2. Use poetry environment in next steps

```
poetry shell
```

or

```
poetry run <command>
```

3. Prepare dataset

```
python3 src/prepare_data.py experiment=<experiment-name>
```

4. Train model

```
CUDA_VISIBLE_DEVICES=<device-id> python3 src/train.py experiment=<experiment-name>
```

5. (optional) Share model to Huggingface Hub

```
python3 src/share_model.py
```

## Evaluation
