How to use hybrid-quantization function
Model Source
The model used in this example come from:
https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/tf1_detection_zoo.md ssd_mobilenet_v2_coco
Script Usage
Usage:
1. python step1.py
2. modify ssd_mobilenet_v2.quantization.cfg according to the prompt of step1.py
3. python step2.py
Description:
- The default target platform in script is 'rk3566', please modify the 'target_platform' parameter of 'rknn.config' according to the actual platform.
- If connecting board is required, please add the 'target' parameter in 'rknn.init_runtime'.
Expected Results
This example will outputs the results of the accuracy analysis and save the result of object detection to the 'result.jpg', as follows:
