You should see packages like hailort, hailo-tappas-core, and hailo-apps-infra.

apt list | grep hailo

This shows all installed Hailo-related system packages.

Hey @kurniawan_anis,

Welcome to the Hailo Community!

The error is coming from the C++ runtime on your system:

/lib/aarch64-linux-gnu/libstdc++.so.6: version 'GLIBCXX_3.4.32' not found (required by .../hailo.cpython-311-aarch64-linux-gnu.so)

What’s happening here is that the Hailo Python extension was compiled against a newer version of libstdc++ than what’s currently on your Raspberry Pi.

The root cause: Looking at your setup, you’ve got a mixed environment that’s causing version conflicts:

  • From RPi repos: hailo-all 4.20.0, hailofw 4.20.0, python3-hailort 4.20.0-1
  • Manually installed: hailort 4.23.0, hailort-pcie-driver 4.23.0, hailo-tappas-core 5.1.0, and hailo-apps-infra 25.10.0 in your venv

You’re essentially running parts of the 4.20 stack alongside newer 4.23/5.1 components, which creates version mismatches. I’ve seen this issue pop up several times on the forum with similar symptoms.

Here’s what I’d recommend — do a clean reinstall:

dpkg -l | grep hailo
sudo apt-get remove --purge -y hailo* libhailo*
sudo apt-get autoremove --purge -y
sudo apt-get clean
sudo apt update
sudo apt full-upgrade
sudo apt install dkms
sudo apt install hailo-all
# to check if worked
hailortcli scan
hailortcli fw-control identify

Let me know how it goes!

Hey @Jericho_Sanchez,

Welcome to the Hailo Community – great to have you here!

Just to double-check: do you have DKMS installed, and you’re still running into this issue? If that’s the case, could you try manually removing the driver from the kernel using the following commands?

sudo find /lib/modules -type f \( -name 'hailo*.ko' -o -name 'hailo*.ko.xz' \) -print -delete
sudo find /lib/modules -type d -name 'hailo' -print -exec rm -rf {} +

After this re run the :

sudo apt update 
sudo apt full-upgrade 
sudo apt install dkms
sudo apt install hailo-all

Hope this helps !

Hey @kurniawan_anis,

Great to see your interest in getting started!

You can find the documentation for the Dataflow Compiler (DFC) here:
v5.1.0 | Hailo
And the Model Zoo is available on GitHub:
GitHub - hailo-ai/hailo_model_zoo: The Hailo Model Zoo includes pre-trained models and a full building and evaluation environment

The process is pretty straightforward:

  1. Start with your ONNX or TensorFlow model.
  2. Parse the model using either the DFC or the Model Zoo.
  • If it’s not already available in the Model Zoo, we recommend using the DFC.
  1. Run the optimization step.
  2. Then proceed to the compilation step.

Hope this helps!
