- ### Module Introduction

  - AttGAN is a Generative Adversarial Network, which uses classification loss and reconstruction loss to train the network. The PaddleHub Module is trained one Celeba dataset and currently supports attributes of "Bald", "Bangs", "Black_Hair", "Blond_Hair", "Brown_Hair", "Bushy_Eyebrows", "Eyeglasses", "Gender", "Mouth_Slightly_Open", "Mustache", "No_Beard", "Pale_Skin", "Aged".


## II. Installation

- ### 1、Environmental Dependence

  - paddlepaddle >= 1.5.2 

  - paddlehub >= 1.0.0  | [How to install PaddleHub](../../../../docs/docs_en/get_start/installation.rst)

- ### 2、Installation

  - ```shell
    $ hub install attgan_celeba==1.0.0
    ```

  - In case of any problems during installation, please refer to:[Windows_Quickstart](../../../../docs/docs_en/get_start/windows_quickstart.md)
    | [Linux_Quickstart](../../../../docs/docs_en/get_start/linux_quickstart.md) | [Mac_Quickstart](../../../../docs/docs_en/get_start/mac_quickstart.md).

 

## III. Module API Prediction

- ### 1、Command line Prediction

  - ```shell
    $ hub run attgan_celeba --image "/PATH/TO/IMAGE" --style "target_attribute" 
    ```

  - **Parameters**

    - image: Input image path.

    - style: Specify the attributes to be converted. The options are "Bald", "Bangs", "Black_Hair", "Blond_Hair", "Brown_Hair", "Bushy_Eyebrows", "Eyeglasses", "Gender", "Mouth_Slightly_Open", "Mustache", "No_Beard", "Pale_Skin", "Aged". You can choose one of the options.

  - If you want to call the Hub module through the command line, please refer to: [PaddleHub Command Line Instruction](../../../../docs/docs_en/tutorial/cmd_usage.rst)



- ### 2、Prediction Code Example

  - ```python
    import paddlehub as hub

    attgan = hub.Module(name="attgan_celeba")

    test_img_path = ["/PATH/TO/IMAGE"]
    trans_attr = ["Bangs"]

    # set input dict
    input_dict = {"image": test_img_path, "style": trans_attr}

    # execute predict and print the result
    results = attgan.generate(data=input_dict)
    print(results)
    ```

- ### 3、API

  - ```python
    def generate(data)
    ```

    - Style transfer API.

    - **Parameter**

      - data(list[dict]): Each element in the list is dict and each field is: 
          - image (list\[str\])： Each element in the list is the path of the image to be converted.
          - style (list\[str\])： Each element in the list is a string, fill in the face attributes to be converted.

    - **Return**
      - res (list\[str\]): Save path of the result.
