Hi,  
I recently installed Kria-PYNQ on my KV260, and it works fine from JupyterLab. But, I sometimes want to use PYNQ applications from the command line. When I was using PYNQ v2.6 on ZCU104, there were no problems in using them either from Jupyter or from the command line. However, I get the following error when Kria-PYNQ (or maybe PYNQ v2.7) is usrd from the command line.

```auto
ubuntu@kria:~$ sudo python3 
[sudo] password for ubuntu: 
Python 3.8.10 (default, Nov 26 2021, 20:14:08) 
[GCC 9.3.0] on linux

>>> import sys
>>> sys.path.append('/usr/local/share/pynq-venv/lib/python3.8/site-packages')
>>> from pynq import Overlay
>>> ol = Overlay('project_1.bit')
/usr/local/share/pynq-venv/lib/python3.8/site-packages/pynq/pl_server/device.py:79: UserWarning: No devices found, is the XRT environment sourced?
  warnings.warn(

    raise RuntimeError("No Devices Found")

```

Is any additional installation for the XRT environment or anything needed? Please let me know any workaround for this problem.

Thanks.  
Tomo.

Hi there,

This is probably because from v2.7 we are running inside a virtual environment.

Instead of running python in sudo try:

```auto
sudo -i
source /etc/profile.d/pynq_venv.sh
python3

```

Thanks  
Shawn
