I got the error : [HailoRT] [error] CHECK_SUCCESS failed with status=HAILO_OUT_OF_PHYSICAL_DEVICES(74)

Is it possible to solve it without reboot the raspberry and hailo ?

Thanks

Hey @user82,

Yes, this can happen when an application using Hailo didn’t close properly. The simple fix is to:

  1. Open your terminal
  2. Run htop
  3. Look for any running Hailo
  4. Kill the remaining process

This should resolve the issue and free up your device.

Best regards,
Omria

As @omria has correctly mentioned, this occurs when the device is essentially in use by another process / not shutdown correctly. To avoid this, ensure you always release the device once finished with it

Taking the HRT_2_Infer_Pipeline_Inference_Tutorial python code as an example,

you might declare your VDevice as follows:

# The target can be used as a context manager ("with" statement) to ensure it's released on time.
# Here it's avoided for the sake of simplicity
target = VDevice()

# other config code etc here
...

If you try to rerun that same block of code again, you’ll hit this error [HAILO_OUT_OF_PHYSICAL_DEVICES(74)](https://community.hailo.ai/t/hailort-error-check-success-failed-with-status-hailo-out-of-physical-devices-74/9511)

but if you include a simple:

target.release()

then it’ll run as expected again.
