ALVEO U280 is not detected by PYNQ

[SPala121]

I have ALVEO U280 connected with my system. I am able to launch kernels on U280 with opencl. But I am trying to work with PYNQ overlays. But PYNQ doesnot detect devices.

import pynq pynq.Device.devices -->this line outputs [ ]

and kernel = pynq.Overlay('vnx_basic_if0.xclbin', device=pynq.Device.devices[0]) ---this line raises following warning:

/home/settysha/anaconda3/lib/python3.9/site-packages/pynq/pl_server/device.py:79: UserWarning: No devices found, is the XRT environment sourced? warnings.warn(

I have following versions of toolchain: pynq- 2.7 XRT-2.14 (also I have sourced xrt) Vitis-2021.2

Hi @SPala121,

Can you try installing pynq 3.0.1?
