# 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:
```bash
sudo apt install libopencv-dev python3-opencv
```
To verify the installation run:
```bash
python3 -c "import cv2; print(cv2.__version__)"
```
### Hailo-8
Confirm the Hailo-8 PCIe Module has been detected
```bash
sudo update-pciids
lspci
```
<pre id=term>04:00.0 Co-processor: Hailo Technologies Ltd. Hailo-8 AI Processor (rev 01)</pre>
### HailoRT
Install HailoRT available from https://hailo.ai/developer-zone/ and confirm the driver is working.
Enter virtual environment
```bash
source hailo_platform_venv/bin/activate
```
Check Hailo firmware
```bash
hailo fw-control identify
```
<pre id=term>(hailo) Running command &apos;fw-control&apos; with &apos;hailortcli&apos;
Identifying board
Control Protocol Version: 2
Firmware Version: 4.4.0 (release,app)
Logger Version: 0
Board Name: Hailo-8
Device Architecture: HAILO8_B0
Serial Number: HAILO00000000000
Part Number: HM218B1C2FA
Product Name: HAILO-8 AI ACCELERATOR M.2 M KEY MODULE
</pre>
### Building the demo
Modify the following line in build.sh to fit your HailoRT installation.
```bash
HAILORT_ROOT=~/HailoRT_v4.4.0/Hailort/Linux/Installer/platform/hailort
```
Build the demo
```bash
./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.
```bash
cd build
./hailo_demo.sh
```
