I have a machine where I only need to inference with openvino, so as stated in the documentation I installed anomalib with only Openvino:

pip install anomalib==1.1.1
anomalib install --option openvino -v

⠋ Installing packages...  This may take a few minutes.

[09:06:21] Installation list: ['nncf>=2.10.0', 'openvino>=2024.0', 'onnx>=1.16.0']   

Then when trying to use the inferencer

from anomalib.deploy import OpenVINOInferencer

I get error:

---------------------------------------------------------------------------

Am I missing something?
