Custom .hef yolov8m pose model error while opening

Hi! I basically I followed the procedure for compiling a custom yolov8m_pose.hef file through WSL and Hailo Dataflow Compiler. I managed to obtain the .hef file but when I try to open it, I get the following error:

[HailoRT] [error] CHECK failed - HEF version does not match. Should be 1 but detected 2
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_INTERNAL_FAILURE(8)
[HailoRT] [error] Failed parsing HEF file
[HailoRT] [error] Failed creating HEF
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_INTERNAL_FAILURE(8)
[HailoRT CLI] [error] CHECK_SUCCESS failed with status=HAILO_INTERNAL_FAILURE(8)

The commands I ran, in order (for the hailo8 version), were:

hailomz parse yolov8m_pose --ckpt best.onnx  
hailomz optimize yolov8m_pose --calib-path train  
hailomz compile yolov8m_pose --har yolov8m_pose.har

The versions I have been using are:

  • packages installed in WSL Ubuntu 22.04 for conversion onnx → hef:
    • golang-github-hailocab-go-hostpool-dev/jammy 0.0~git20160125.0.e80d13c-1.1 all
    • hailort/now 4.20.0 amd64 [installed,local]
    • hailo-dataflow-compiler 3.31.0
    • hailo-model-zoo 2.15.0 /home/btsuser/hailo_model_zoo
    • hailort 4.20.0
  • packages installed in a RaspberryPi 5, on which I would like to open the hef file (thorugh C++ project):
    • golang-github-hailocab-go-hostpool-dev/stable,stable 0.0~git20160125.0.e80d13c-1.1 all
    • hailo-all/stable,stable 4.20.0 all
    • hailo-dkms/stable,stable,now 4.19.0-1 all [installed]
    • hailo-tappas-core-3.28.2/stable 3.28.2 arm64
    • hailo-tappas-core/stable 3.31.0+1-1 arm64 [upgradable from: 3.30.0-1]
    • hailofw/stable,stable,now 4.20.0-1 all [installed,automatic]
    • hailort-pcie-driver/now 4.19.0 all [installed,local]
    • hailort/stable 4.20.0-1 arm64 [upgradable from: 4.19.0-3]
    • python3-hailort/stable 4.20.0-1 arm64 [upgradable from: 4.19.0-2]
    • rpicam-apps-hailo-postprocess-dbgsym/stable 1.7.0-1 arm64
    • rpicam-apps-hailo-postprocess/stable 1.7.0-1 arm64

Any help would be appreciated, thanks.

Dataflow Compiler v3.31.0 (March 2025)
Compiler
• Using XXHASH3_64 for error-detection in HEF files while previously were using CRC32. Older HailoRT
versions may not work with HEF files compiled in this version.

DFC 3.31 uses a new checksum algorithm. Either upgrade to HailoRT 4.21 or recompile with DFC 3.30 or lower.

I tried at 3.30 version and gave a lot of other errors.
