Model licensing

The Pytorch-Wildlife package is under MIT, however some of the models in the model zoo are not. For example, MegaDetectorV5, which is trained using the Ultralytics package, a package under AGPL-3.0, and is not for closed-source commercial uses if they are using updated 'ultralytics' packages.

There may be a confusion because YOLOv5 was initially released before the establishment of the AGPL-3.0 license. According to the official Ultralytics-Yolov5 package, it is under AGPL-3.0 now, and the maintainers have discussed how their licensing policy has evolved over time in their issues section.

We want to make Pytorch-Wildlife a platform where different models with different licenses can be hosted and want to enable different use cases. To reduce user confusions, in our model zoo section, we list all existing and planned future models in our model zoo, their corresponding license, and release schedules.

In addition, since the Pytorch-Wildlife package is under MIT, all the utility functions, including data pre-/post-processing functions and model fine-tuning functions in this packages are under MIT as well.
