Images in different directories

[siiigrid]

Is there any way to execute it with all my images at once if they are in directories like this?:
.
└── images/
├── 1/
│ ├── im1.png
│ ├── im2.png
│ └── im3.png
├── 2/
│ ├── im4.png
│ ├── im5.png
│ └── im6.png
└── 3/
├── im7.png
├── im8.png
└── im9.png

You can create a .txt file containing you stream sources

path/to/1/
path/to/2/
path/to/3/

finally you can run

python3 track.py --source streams.txt
