🐾 Introduction

At the core of our mission is the desire to create a harmonious space where conservation scientists from all over the globe can unite. Where they're able to share, grow, use datasets and deep learning architectures for wildlife conservation. We've been inspired by the potential and capabilities of Megadetector, and we deeply value its contributions to the community. As we forge ahead with Pytorch-Wildlife, under which Megadetector now resides, please know that we remain committed to supporting, maintaining, and developing Megadetector, ensuring its continued relevance, expansion, and utility.

Pytorch-Wildlife is pip installable:

pip install PytorchWildlife

To use the newest version of MegaDetector with all the existing functionalities, you can use our Hugging Face interface or simply load the model with Pytorch-Wildlife. The weights will be automatically downloaded:

from PytorchWildlife.models import detection as pw_detection
detection_model = pw_detection.MegaDetectorV6()

For those interested in accessing the previous MegaDetector repository, which utilizes the same MegaDetectorV5 model weights and was primarily developed by Dan Morris during his time at Microsoft, please visit the archive directory, or you can visit this forked repository that Dan Morris is actively maintaining.

[!TIP] If you have any questions regarding MegaDetector and Pytorch-Wildlife, please email us or join us in our discord channel:

📣 Announcements

🎉🎉🎉 Pytorch-Wildlife Version 1.1.0 is out!

• MegaDetectorV6 is finally out! Please refer to our next section and our release notes for more details!
• We have incorporated a point-based overhead animal detection model into our model zoo called HerdNet (Delplanque et al. 2022). Two model weights are incorporated in this release, HerdNet-general (their default weights) and HerdNet-ennedi (their model trained on Ennedi 2019 datasets). More details can be found here and in their original repo. This is the first third-party model in Pytorch-Wildlife and the foundation of our expansion to overhead/aerial animal detection and classification. Please see our HerdNet demo on how to use it!
• You can now load custom weights you fine-tuned on your own datasets using the finetuning module directly in the Pytorch-Wildlife pipeline! Please see the demo on how to do it. You can also load it in our Gradio app!
• You can now automatically separate your image detections into folders based on detection results! Please see our folder separation demo on how to do it. You can also test it in our Gradio demo!
• We have also simplified the batch detection pipeline. Now we do not need to define pytorch datasets and dataloaders specifically. Please make sure to change your code and check our release notes and our new demo for more details.

:racing_car::dash::dash: MegaDetectorV6: SMALLER, BETTER, and FASTER!

After a few months of public beta testing, we are finally ready to officially release our 6th version of MegaDetector, MegaDetectorV6! In the next generation of MegaDetector, we are focusing on computational efficiency, performance, mordernizing of model architectures, and licensing. We have trained multiple new models using different model architectures, including Yolo-v9, Yolo-v11, and RT-Detr for maximum user flexibility. We have a rolling release schedule for different versions of MegaDetectorV6, and in the first step, we are releasing the compact version of MegaDetectorV6 with Yolo-v9 (MDv6-ultralytics-yolov9-compact, MDv6-c in short). From now on, we encourage our users to use MegaDetectorV6 as their default animal detection model.

This MDv6-c model is optimized for performance and low-budget devices. It has only one-sixth (SMALLER) of the parameters of the previous MegaDetectorV5 and exhibits 12% higher recall (BETTER) on animal detection in our validation datasets. In other words, MDv6-c has significantly fewer false negatives when detecting animals, making it a more robust animal detection model than MegaDetectorV5. Furthermore, one of our testers reported that the speed of MDv6-c is at least 5 times FASTER than MegaDetectorV5 on their datasets.

Learn how to use MegaDetectorV6 in our image demo and video demo.

:bangbang: Model licensing (IMPORTANT!!)

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, is under AGPL-3.0, and is not for closed-source comercial uses.

[!IMPORTANT] THIS IS TRUE TO ALL EXISTING MEGADETECTORV5 MODELS IN ALL EXISTING FORKS THAT ARE TRAINED USING YOLOV5, AN ULTRALYTICS-DEVELOPED MODEL.

We want to make Pytorch-Wildlife a platform where different models with different licenses can be hosted and want to enable different usecases. To reduce user confusions, in our model zoo section, we list all existing and planed 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.

Detection models

Classification models

👋 Welcome to Pytorch-Wildlife

PyTorch-Wildlife is a platform to create, modify, and share powerful AI conservation models. These models can be used for a variety of applications, including camera trap images, overhead images, underwater images, or bioacoustics. Your engagement with our work is greatly appreciated, and we eagerly await any feedback you may have.

The Pytorch-Wildlife library allows users to directly load the MegaDetector model weights for animal detection. We've fully refactored our codebase, prioritizing ease of use in model deployment and expansion. In addition to MegaDetector, Pytorch-Wildlife also accommodates a range of classification weights, such as those derived from the Amazon Rainforest dataset and the Opossum classification dataset. Explore the codebase and functionalities of Pytorch-Wildlife through our interactive HuggingFace web app or local demos and notebooks, designed to showcase the practical applications of our enhancements at PyTorchWildlife. You can find more information in our documentation.

👇 Here is a brief example on how to perform detection and classification on a single image using PyTorch-wildlife

import numpy as np
from PytorchWildlife.models import detection as pw_detection
from PytorchWildlife.models import classification as pw_classification

img = np.random.randn(3, 1280, 1280)

# Detection
detection_model = pw_detection.MegaDetectorV6() # Model weights are automatically downloaded.
detection_result = detection_model.single_image_detection(img)

#Classification
classification_model = pw_classification.AI4GAmazonRainforest() # Model weights are automatically downloaded.
classification_results = classification_model.single_image_classification(img)

⚙️ Install Pytorch-Wildlife
