pyvisa: pyvisa.errors.VisaIOError: VI_ERROR_RSRC_NFOUND (-1073807343): Insufficient location information or the requested device or resource is not present in the system.

I am trying to use pyvisa to connect a Keysight Network Analyser (E5071C). I can successfully do that in one Dell laptop with CentOS 7.5. But I cannot do that in a Intel NUC with CentOS 7.7, where I get this error:

>>> import visa
>>> rm = visa.ResourceManager()
>>> rm.list_resources()
('ASRL1::INSTR', 'ASRL2::INSTR', 'ASRL3::INSTR', 'ASRL4::INSTR', 'TCPIP0::169.254.158.139::A-E5071C-15158::INSTR')
>>> rm.open_resource('TCPIP0::169.254.158.139::A-E5071C-15158::INSTR')

Here are the “python -m visa info” for both cases. In the successful one, it is:

In the failed one, there are two backends because I tried installing pyvisa-py as well (unfortunately both not working.)
