-   Initialize your output stream, and your path, and import in the Image library

.. code-block:: python

    from IPython.display import Image

    %env DISPLAY=:0
    %env PROGRAM_PATH=/home/zeta/jetson-inference/build/aarch64/bin
    %env INPUT_PATH=/home/zeta/jetson-inference/build/aarch64/bin/images
    %env OUTPUT_PATH=/home/zeta/jetson-inference/build/aarch64/bin/images/test

    input_path='/home/zeta/jetson-inference/build/aarch64/bin/images'
    output_path='/home/zeta/jetson-inference/build/aarch64/bin/images/test'



-   Check all the available human pictures within the system

    .. code-block:: python

        !ls $INPUT_PATH/human_*


    .. thumbnail:: /_images/ai_tao/face_list.png

|

-   Pick one of the image with human(s) and initialize the image/ output name. 

    .. code-block:: python

        image_name = 'ChangeMe'
        output_name = 'face_result.jpg'
        %env IMAGE_NAME = $image_name
        %env OUTPUT_NAME = $output_name

        Image(filename=input_path+'/'+image_name) 


-   Guess the pose!

    .. code-block:: python

        %%capture
        !python3 $PROGRAM_PATH/detectnet.py --network=facedetect $INPUT_PATH/$IMAGE_NAME $OUTPUT_PATH/$OUTPUT_NAME




|

-   Show the resulting image


    .. code-block:: python

        Image(filename=output_path+'/face_result.jpg')
