i found https://developer.nvidia.com/blog/create-custom-character-detection-and-recognition-models-with-nvidia-tao-part-1/
this one helpful for me but i little bit confused about the structure of dataset .
In orignal doc

/Dataset
    /images
        0000.jpg
        0001.jpg
        0002.jpg
        ...
    gt_list.txt
    characters_list.txt

but in blog its quite different

thank you
