The Segment Anything Model (SAM) produces high quality object masks from input prompts such as points or boxes, and it can be used to generate masks for all objects in an image. It has been trained on a dataset of 11 million images and 1.1 billion masks, and has strong zero-shot performance on a variety of segmentation tasks.
The code requires python>=3.8, as well as pytorch>=1.7 and torchvision>=0.8. Please follow the instructions here to install both PyTorch and TorchVision dependencies. Installing both PyTorch and TorchVision with CUDA support is strongly recommended.
Install Segment Anything:
or clone the repository locally and install with
The following optional dependencies are necessary for mask post-processing, saving masks in COCO format, the example notebooks, and exporting the model in ONNX format. jupyter is also required to run the example notebooks.
First download a model checkpoint. Then the model can be used in just a few lines to get masks from a given prompt:
or generate masks for an entire image:
Additionally, masks can be generated for images from the command line:
See the examples notebooks on using SAM with prompts and automatically generating masks for more details.
SAM's lightweight mask decoder can be exported to ONNX format so that it can be run in any environment that supports ONNX runtime, such as in-browser as showcased in the demo. Export the model with
See the example notebook for details on how to combine image preprocessing via SAM's backbone with mask prediction using the ONNX model. It is recommended to use the latest stable version of PyTorch for ONNX export.
Three model versions of the model are available with different backbone sizes. These models can be instantiated by running

We save masks per image as a json file. It can be loaded as a dictionary in python in the below format.
Image ids can be found in sa_images_ids.txt which can be downloaded using the above link as well.
