Hailo-apps-Infra Installation completed but with errors detected

General Discussion

Newbie here, can anyone help me if the current version of hailo-apps–infra is compatible with Rpi5 with Hailo8L, as I’m having issue when executing below command:

1. Clone the repository

git clone GitHub - hailo-ai/hailo-apps-infra cd hailo-apps-infra

2. Run the automated installation script

./install.sh

Here’s the error I have got:

ion-0.4.1 tzdata-2025.2 uvicorn-0.35.0 websockets-15.0.1

Hi @mjl06 ,

This error is a bit funny. The reason you get UnicodeEncodeError: ‘latin-1’ codec can’t encode character ‘\U0001f527’ in position 0: ordinal not in range(256) is because there’s an emoji, and latin-1 can’t deal with emojis.

This is a quick fix only for the terminal session you run it in. It’ll temporarily force Python to use UTF-8 encoding:


export PYTHONUTF8=1
export PYTHONIOENCODING=UTF-8
export LANG=C.UTF-8
export LC_ALL=C.UTF-8
./install.sh

For a more permanent fix, you’ll need to change your terminal’s default encoding to UTF-8 .

You can replicate this issue with this one-liner: PYTHONIOENCODING=latin-1 python3 -c ‘print(“🔧”)’
