Hef has periph_calculation_in_hailort feature disabled

Hello,
I’m using tiny_yolov4_license_plates.hef with HailoRT 4.21.0, but I get unsupported error.

Loading model: ./tiny_yolov4_license_plates.hef
[HailoRT] [error] CHECK failed - Hef has periph_calculation_in_hailort feature disabled - this HEF is outdated and no longer supported. Please update HEF
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_HEF_NOT_SUPPORTED(92)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_HEF_NOT_SUPPORTED(92)
[HailoRT] [error] Failed parsing HEF file
[HailoRT] [error] Failed creating HEF
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_HEF_NOT_SUPPORTED(92)

Can somebody tell me how to modify the HEF to make it compatible with HailoRT 4.21.0? I assume I have to use DFC to modify the hef file.

Thanks.

The HEF file is a binary and cannot be changed. For now you can only use HailoRT 4.20. I just checked and the model is still running with that version.
I will check with my colleagues and see what can be done.

My colleagues have updated the model HEF files. You can download them from the Model Zoo.

Please note that the output vectors changed.

@KlausK Sorry for taking so long, but I have only now got around to use the model.

The model is compiled for HAILO15H, whereas the previous version was for HAILO8, which is what I’m using.

Is it possible to have it ocmpiled for HAILO8 as well?

Thanks
