## OCR model list（V2.0, updated on 2021.1.20）
**Note** : Compared with [models 1.1](https://github.com/PaddlePaddle/PaddleOCR/blob/develop/doc/doc_en/models_list_en.md), which are trained with static graph programming paradigm, models 2.0 are the dynamic graph trained version and achieve close performance.

- [1. Text Detection Model](#Detection)
- [2. Text Recognition Model](#Recognition)
    - [Chinese Recognition Model](#Chinese)
    - [English Recognition Model](#English)
    - [Multilingual Recognition Model](#Multilingual)
- [3. Text Angle Classification Model](#Angle)

The downloadable models provided by PaddleOCR include `inference model`, `trained model`, `pre-trained model` and `slim model`. The differences between the models are as follows:

|model type|model format|description|
|--- | --- | --- |
|inference model|inference.pdmodel、inference.pdiparams|Used for reasoning based on Python prediction engine，[detail](./inference_en.md)|
|trained model, pre-trained model|\*.pdparams、\*.pdopt、\*.states |The checkpoints model saved in the training process, which stores the parameters of the model, mostly used for model evaluation and continuous training.|
|slim model|\*.nb|Generally used for Lite deployment|

**Note:** The `trained model` is finetuned on the `pre-trained model` with real data and synthsized vertical text data, which achieved better performance in real scene. The `pre-trained model` is directly trained on the full amount of real data and synthsized data, which is more suitable for finetune on your own dataset.

<a name="Multilingual"></a>
#### Multilingual Recognition Model（Updating...）

**Note：** The configuration file of the new multi language model is generated by code. Take the Italian configuration file as an example：

```bash
# The code needs to run in the specified directory
cd PaddleOCR/configs/rec/multi_language/
# Set the required language configuration file through -l or --language parameter
# This command will write the default parameter to the configuration file.
python3 generate_multi_language_configs.py -l it
```
You can use the `--help` parameter to check which multi language are supported by current PaddleOCR.

```bash
python3 generate_multi_language_configs.py --help
```
If you don't want to use the default path or default parameters, you can modify them according to the following command：
```bash
# The -l or --language parameter is required
# --train modify train_list path
# --val modify eval_list path 
# --data_dir modify data dir
# -o modify default parameters
python3 generate_multi_language_configs.py -l it \
--train {path/to/train_list} \
--val {path/to/val_list} \
--data_dir {path/to/data_dir} \
-o Global.use_gpu=False
```
