Users are seeing the following error with newer (550) drivers:

 File "/home/lab/miniconda3/envs/rapids-23.06-3.9/lib/python3.9/site-packages/pynvml/nvml.py", line 765, in _nvmlCheckReturn
    raise NVMLError(ret)
pynvml.nvml.NVMLError_NotSupported: Not Supported

...

 File "/home/lab/miniconda3/envs/rapids-23.06-3.9/lib/python3.9/site-packages/ucp/__init__.py", line 68, in <module>
    bar1_total = pynvml.nvmlDeviceGetBAR1MemoryInfo(handle).bar1Total
  File "/home/lab/miniconda3/envs/rapids-23.06-3.9/lib/python3.9/site-packages/pynvml/nvml.py", line 2070, in nvmlDeviceGetBAR1MemoryInfo
    _nvmlCheckReturn(ret)

It has been confirmed offline that pynvml is correctly returning NVMLError_NotSupported for nvmlDeviceGetBAR1MemoryInfo, because this device does not support Bar1 accesss.

The ucp/__init__.py logic should be updated to account for a NVMLError_NotSupported exception.
