ModuleNotFoundError: No module named 'hailort' on Raspberry Pi 5 (HailoRT 4.20.0 Installed)

General

Hi Hailo Team,

I’m working on a project using Raspberry Pi 5 (aarch64) with a Hailo-8 M.2 accelerator. I’ve followed the official installation instructions and have successfully installed:

HailoRT 4.20.0

Python 3.11

hailort Python wheel for aarch64 (hailort-4.20.0-cp311-cp311-linux_aarch64.whl)

Everything seems installed correctly:

hailortcli scan detects my Hailo-8 device.

dpkg -l | grep hailo shows all related packages including python3-hailort.

The wheel installation completes without errors.

However, when I try to import hailort in Python, I always get:

ModuleNotFoundError: No module named ‘hailort’

Even though:

pip show hailort confirms it’s installed.

Python sys.path includes /usr/lib/python3/dist-packages where hailort seems to live.

ldconfig -p | grep hailort shows shared libs are present (libhailort.so etc).

$PYTHONPATH is set correctly.

I tried everything:

Installing via .deb and .whl

Setting PYTHONPATH

Rebuilding the virtual environment

Testing both inside and outside the virtual environment

Reinstalling all Hailo packages

Still no success. I suspect it may be related to how hailort is structured inside the wheel or how it is referenced (hailo_platform.drivers.hailort.pyhailort instead of hailort?).
:red_question_mark: My Questions:

What is the correct way to import and use hailort in Python 3.11 on aarch64?

Is there an __init__.py or symbolic import missing in the package?

Should I avoid virtual environments with HailoRT?

Is there a working example of using the .whl file on Raspberry Pi OS 64-bit with Python 3.11?

What did you try?

ubuntu@ubuntu-2404-pi5b:~$ python3
Python 3.12.3 (main, Feb  4 2025, 14:48:35) [GCC 13.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import hailort
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'hailort'
>>>

but

ubuntu@ubuntu-2404-pi5b:~$ python3
Python 3.12.3 (main, Feb  4 2025, 14:48:35) [GCC 13.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import hailo
>>>

Maybe, it’s that easy?!
