hailo-CLIP can't load clip_resnet_50x4_h8l.hef and segfaults with --input=rpi

Hello,
I am having trouble running the halio-CLIP app on a raspberry pi 5 with a Hailo 8L chip. I cloned the repo and ran the install script. When I enter the venv and try and run the demo app with python clip_application.py --input demo, I see this in the output

[HailoRT] [error] CHECK failed - Error opening file <actual path here>/clip_resnet_50x4_h8l.hef
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_OPEN_FILE_FAILURE(13)
[HailoRT] [error] Failed parsing HEF file
[HailoRT] [error] Failed creating HEF
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_OPEN_FILE_FAILURE(13)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_OPEN_FILE_FAILURE(13)
[HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_OPEN_FILE_FAILURE(13)

The main window for the app with the sliders and text box pops up, and I can change values/move sliders/click buttons. But nothing else happens with the demo.

The clip_resnet_50x4_h8l.hef that gives the error above does exist at the expected path, and it has permissions 644.

Additionally, if I try and run python clip_application.py --input rpi, I get the same error about failing to open the hef file, and the program eventually segfaults.

2025-07-10 00:55:03,284 - clip_app.logger_setup - INFO - Text box 0 is set to negative: True

For reference, I have successfully run the basic_pipelines/detection.py example from the hailo-rpi5-examples repo, successfully getting detections wiith my rpi camera, so my setup seems to be working in that regard.

Any help would be appreciated, thanks in advance!

Hey,

Can you provide the output of the following command?
hailortcli fw-control identify

Also, I’d suggest to check this thread, for now steps 1-4.
