I am trying to run my own code on hailo.

python3 gamma2.py -n ./detModelNet.hef -i car1.jpg

And I am facing this error …

[HailoRT] [error] CHECK failed - Failed to create vdevice. there are not enough free devices. requested: 1, found: 0

The above exception was the direct cause of the following exception:

Can anyone please guide me ?

Hey @Himanshu_Panjwani,

This happens when another application is holding the Hailo device. It might be due to an incorrect application closure or something similar.

I recommend running htop and checking which applications that used hailo and still active in the background!
