ad9081_tdd_example.py code run error

Hello,

I am testing the ad9081_tdd_example code: https://github.com/analogdevicesinc/pyadi-iio/blob/a5eb253aa30678fead58dae7df06b9a7dce3c1be/examples/ad9081_tdd_example.py#L14

My hardware setup is ZCU102 + AD9081 Evaluation board. I run the above code on the VMware Ubuntu 20.04. 

But there are some errors:

pci@pci-virtual-machine:~/Documents$ /bin/python3 /home/pci/Documents/ad9081.py
Traceback (most recent call last):

    raise OSError(-result, _strerror(-result))
TimeoutError: [Errno 110] Connection timed out

Could you give me some advice? Thanks!

Best,
