NPU is not recognized in virtual environment

My device is 255H, my system is ubuntu-24.04, the kernel version is 6.11, and the commands `lsmod | grep intel_vpu` and `modinfo intel_vpu `can both show the existence of `intel_vpu`, and` ls /dev/accel/accel0` can also see `accel0`, and I have also installed **_Level Zero_** through **deb**, why can't npu be recognized in my **python virtual environment**? The command `python -c "from openvino import Core; print(Core().available_devices)"` only outputs **['CPU', 'GPU']**,What else do I need to do to correctly identify the NPU？
