To enhance `pyvisa-py`'s capabilities and avoid warnings related to resource discovery (e.g., for TCPIP or HiSLIP instruments), it is highly recommended to also install `psutil` and `zeroconf`: `pip install psutil zeroconf`. It can be used as a fallback but may have limitations compared to vendor-specific drivers like NI-VISA. Note that for direct GPIB communication via `pyvisa-py`, a separate GPIB library (e.g., from your GPIB adapter vendor) might still be required.
