TAO Pretrained ODISE 1.1
Train Adapt Optimize (TAO) Toolkit is a Python-based AI toolkit for taking purpose-built pre-trained AI models and customizing them with your own data. TAO adapts popular network architectures and backbones to your data, allowing you to train, fine tune, prune, and export highly optimized and accurate AI models for edge deployment.
Pre-trained models accelerate the AI training process and reduce costs associated with large scale data collection, labeling, and training models from scratch. Transfer learning with pre-trained models can be used for AI applications in smart cities, retail, healthcare, industrial inspection, and more.
Build end-to-end services and solutions for transforming pixels and sensor data to actionable insights using TAO DeepStream SDK and TensorRT. These models are suitable for object detection, classification, and segmentation.
Open-vocabulary DIffusion-based panoptic SEgmentation (ODISE) developed by NVIDIA Research is an open vocabulary panoptic segmentation model. It leverages the frozen representation of pre-trained text-image diffusion and discriminative models to perform panoptic segmentation of any category in the wild. ODISE 1.1 is a TAO optimized version which replaces the diffusion backbone with the ConvNext based CLIP backbone.
The model in this instance is a panoptic segmentator that takes color (RGB) images and text prompts as inputs and generates segmentation masks and associated labels as outputs. The backbone feature extractor of this model is the ConvNext-L CLIP model pretrained on LAION-2B dataset.
This model was trained using the ODISE 1.1 implementation in TAO Toolkit available as a developer preview with TAO 5.2.0.
ODISE 1.1 was trained on the COCO dataset for Panoptic Segmentation. The COCO dataset contains 118K training images and 5K validation images and corresponding annotation files. The annotation includes bounding boxes and segmentation masks of the 80 thing categories from the detection task and a subset of the 91 stuff categories from the stuff task.
We test the ODISE 1.1 model on the COCO 2017 validation dataset.
Methodology and KPI
The KPI for the evaluation data are reported below.
How to Use This Model
This model needs to be used with NVIDIA Hardware and Software. For Hardware, the model can run on any NVIDIA GPU with sufficient memory (>12G). This model can only be used with TAO Toolkit.
The primary use case for these models is open-vocabulary segmentation and auto-labeling.
It is intended for training and fine-tune using Train Adapt Optimize (TAO) Toolkit and the users' dataset of object detection. High fidelity models can be trained to new use cases. A Jupyter notebook is available as a part of TAO container and can be used to re-train.

Instructions to Use Pretrained Models with TAO
To use these models as pretrained weights for demo or transfer learning, please refer to README
ODISE 1.1 was trained on the COCO dataset with roughly 200 object categories and heavily relies on the frozen CLIP model. Hence, the model may not perform well on data from completely different domains. We recommend further fine tuning on the target domain to get higher PQ/mIoU/AP.
