EdgeFirst Validator

EdgeFirst Validator

EdgeFirst Validator is a Python CLI tool for validating computer vision models (object detection, instance segmentation, semantic segmentation, multitask) against annotated datasets. It supports multiple inference backends — ONNX, TFLite, Keras, TensorRT, DeepViewRT, and Kinara Ara2 — and integrates with EdgeFirst Studio for cloud and on-target validation workflows. Published to PyPI as edgefirst-validator.

Installation

For on target validation, the system may already contain the dependencies needed to run the model such as tflite_runtime for TensorFlow Lite. In such cases, it is recommended to first create a python virtual environment with the --system-site-packages option enabled.

EdgeFirst-Validator is available in PyPI and can be installed via pip.

pip install edgefirst-validator

Validation of specific models requires these installations which includes the packages needed to run the models, in case the system at present does not contain these packages.

• HAL (GPU-accelerated preprocessing and mask decoding): pip install edgefirst-validator[hal]
• Keras: pip install edgefirst-validator[keras]
• ONNX: pip install edgefirst-validator[onnx]
• TensorRT: pip install edgefirst-validator[tensorrt]
• TFLite: pip install edgefirst-validator[tflite]
• Studio (all backends for cloud validation): pip install edgefirst-validator[studio]

Usage

1. As a quickstart, deploy default validation of a YOLOv5 model with COCO128 dataset.

   edgefirst-validator
   

2. Deploy validation as a user-managed session in EdgeFirst Studio. First login with EdgeFirst Client.

   edgefirst-client login
   

   edgefirst-validator --session-id <validator session ID>
   

   Otherwise, you can specify the credentials directly.

   edgefirst-validator --token <token> --session-id <validator session ID>
   

   edgefirst-validator --username <username> --password <password> --session-id <Validator Session ID>
   

3. Deploy standalone validation.

   edgefirst-validator <model path> <dataset path>
