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[HailoRT] [error] CHECK failed - Hef has periph_calculation_in_hailort feature disabled - this HEF is outdated and no longer supported.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.
