Hello! I am trying to get my AI Hat+ (26 Tops) up and running on my RPi5. I’ve tried many installation guides, mainly for Hailo-Apps v25.10.0, but it seems when i run ./install.sh from hailo-apps-infra, I get:

-in the log file. However, I cannot find the arm64 system package for hailo-tappas-core anywhere, not in the Developer Zone, or the artifacts folder from extracting the software suite. Am I missing something here? Thank you.

Hi @Fridrihs_Olsteins,

Thanks for sharing - we identified the issue and working to fix ASAP.
In the meanwhile it’s possible to get all required files from our developer zone: https://hailo.ai/developer-zone/

Please see details here: hailo-apps/doc/user_guide/installation.md at main · hailo-ai/hailo-apps · GitHub

Thanks,
Michael.

Hi @Fridrihs_Olsteins ,

Issue fixed. Now it’s working.

Thanks

Hello, I am experiencing a version mismatch issue while trying to install the hailo-apps infrastructure on my Raspberry Pi.

The installation script fails during the validation step because it detects a compatibility conflict between HailoRT and TAPPAS for the hailo8 architecture. According to the logs, my current setup is:

HailoRT: 4.23.0
TAPPAS: 5.2.0

However, the installer expects TAPPAS 5.1.0 to work with HailoRT 4.23.0.

Log Snippet:

Plaintext

[2026-05-12 10:30:58] [WARNING] HailoRT 4.23.0 + TAPPAS 5.2.0 is not a valid combination for hailo8
[2026-05-12 10:30:58] [WARNING] Valid combinations for hailo8: 4.23.0:5.1.0
[2026-05-12 10:30:58] [ERROR] Version validation failed - installation cannot continue

Request: I have searched the Hailo Developer Zone, but I can only find the download link for TAPPAS v5.2.0. Could you please provide a direct download link for TAPPAS Core v5.1.0 or advise on how to resolve this mismatch?

Hi @Jose_Fuertes,

Can you please try this?

Thanks,
Michael.

Hi @Michael
I have applied the filters detailed below, but the arm64 architecture version for the Raspberry Pi 5 (with Hailo-8 26 TOPS) is not appearing. While I found versions for Ubuntu, I cannot find TAPPAS Core v5.1.0 for Raspberry Pi.

I have also tried different filters by changing the Python versions and searched using both ‘tappas’ and ‘core’ as keywords, but I still cannot locate the required hailo-tappas-core_5.1.0 package for arm64.

Jose_Fuertes · May 14, 2026, 5:36pm

**
Following your suggestions, I have checked using the filters you mentioned**, but I can confirm that TAPPAS Core version 5.1.0 is still not visible for the ARM64 architecture (Raspberry Pi).

When searching, I only see versions 5.2.0 and 5.3.0 (the latter being compatible only with Hailo-10 according to the official page). Although the Python binding v5.1.0 is available, the TAPPAS Core is not. I have also tried to compile directly from hailo_core_apps/releases without success.

Request: For Hailo-8 installations, could you please provide:

A validated setup combining PCIe 4.23 with TAPPAS Core 5.2.0.
Or a direct link to the .deb package for version 5.1.0 (ARM64 / Raspberry Pi 5) for the Hailo-8 (26 TOPS) module

Michael · May 15, 2026, 5:26am

Hi @Jose_Fuertes , Indeed looks like the 5.1 is currently missing, we are working on it

user1046 · May 15, 2026, 6:47am

Mark_Colley · May 16, 2026, 9:43am

Hey there, I also need this version thanks a lot for your effort - is there any estimation as to when will be available?

Mark_Colley · May 16, 2026, 10:16am

Can we just use

wget https://archive.raspberrypi.org/debian/pool/main/p/python-hailo-tappas/python3-hailo-tappas_5.1.0_arm64.deb

?

Mark_Colley · May 16, 2026, 10:27am

wget https://archive.raspberrypi.org/debian/pool/main/p/pyhailort/python3-hailort_4.23.0-1_arm64.deb

wget https://archive.raspberrypi.org/debian/pool/main/p/python-hailo-tappas/python3-hailo-tappas_5.1.0_arm64.deb

user1046 · May 20, 2026, 6:05am

thank you but it just supports python 3.13
how about python 3.11 or 3.10?

hailo apps infra git require python 3.11
