Hi Hailo Support Team,
I am working on a custom home automation project using Hailo-10H M.2 (PCIe) on an x86 Ubuntu 22.04 machine. I have fine-tuned Qwen2-1.5B-Instruct with custom LoRA adapters and I am trying to compile them into a .hef file for deployment on Hailo-10H.
System setup:
- Hardware: Hailo-10H M.2 (03:00.0 PCIe, detected via lspci)
- OS: Ubuntu 22.04, x86_64
- HailoRT version: 5.3.0
- DFC version: 5.3.0
- Base model: Qwen2-1.5B-Instruct (fine-tuned with LoRA, rank 16)
The Problem:
When I load the only available HAR file for Qwen2-1.5B-Instruct downloaded from the Hailo Developer Zone GenAI model page, I get the following error:
hailo_sdk_client.runner.exceptions.IncompatibleDFCVersionException:
HAR DFC version 5.1.0.dev0 is too old for GenAI models.
Please download a HAR with DFC version 5.2 or higher from the Hailo Model Zoo GenAI website.
However, on the Developer Zone Software Downloads page, only DFC version 5.3.0 is available — there is no 5.2.0 or 5.1.0 to download. This means:
- The HAR available on the GenAI model page was built with SDK 5.1.0.dev0
- DFC 5.3.0 rejects this HAR as incompatible
- No older DFC version is available to download to match the HAR
- This completely blocks all custom LoRA deployment on Hailo-10H
This was also confirmed by other users in the community (thread: HAR cannot be recompiled with DFC 5.2.0 due to Context-Partition Topology Error).
My Request:
Could you please release a DFC 5.3.0 compatible HAR file for Qwen2-1.5B-Instruct on the GenAI model page? This is the only path forward for deploying custom LoRA fine-tuned models on Hailo-10H with the current toolchain.
This is blocking our production deployment. Any timeline or workaround would be greatly appreciated.
Thank you,
