I am getting this error while running the usrp2_card_burner_gui.py

Traceback (most recent call last):

I searched in web but couldn’t find something accurate

Somebody has mentioned the same thing this year
diff --git a/host/utils/usrp2_card_burner.py b/host/utils/usrp2_card_burner.py - Pastebin.com but I couldn’t understand what is the
solution

Well I got the solution

Its some python version problem. With 2.7.2 its working fine. I have 2.6
in
the problematic systems.

So told by Josh I removed the " errors=‘ignore’ " from
usrp2_card_burner.py
from line 53

and it worked finally. :smiley:

This is not a gnuradio problem. Its a UHD bug that was introduced from a
language fix for the card burner. So I can fix it, please tell me:

What version of python are you running?

Does the app work if you remove “errors=‘ignore’”?
