YOLOV5 Age Gender Model Demo

This example demonstrates basic usage of HailoRT streaming API over multiple networks, using vstreams. It loads a folder of images and tries to detect faces in them. Once it found a face it will switch to a different model that will do age and gender recognition.

Setup on Ubuntu 20.04

OpenCV

To install OpenCV run:

sudo apt install libopencv-dev python3-opencv

To verify the installation run:

python3 -c "import cv2; print(cv2.__version__)"

Hailo-8

Confirm the Hailo-8 PCIe Module has been detected

sudo update-pciids
lspci

04:00.0 Co-processor: Hailo Technologies Ltd. Hailo-8 AI Processor (rev 01)

HailoRT

Install HailoRT available from https://hailo.ai/developer-zone/ and confirm the driver is working.

Enter virtual environment

source hailo_platform_venv/bin/activate

Check Hailo firmware

hailo fw-control identify

Building the demo

Modify the following line in build.sh to fit your HailoRT installation.

HAILORT_ROOT=~/HailoRT_v4.4.0/Hailort/Linux/Installer/platform/hailort

Build the demo

./build.sh

After building the hailo_demo, the script will copy the two HEF files and the images directory into the build folder. Run the demo.

cd build
./hailo_demo.sh
