    .. code-block:: bash

        $ python3 -c "from openvino import Core; ie = Core(); print(ie.available_devices)"
        ['CPU']

    Please firstly make sure you have installed the :doc:`firmware <installation_setup/installation/gpu_firmware>` and :doc:`driver <installation_setup/installation/client_gpu_driver>` for GPU. If you are still encountering this issue:

    .. code-block:: bash

        $ export OCL_ICD_VENDORS=/etc/OpenCL/vendors
