KhalidBest regards,Thank you.Please note that on an older machine, GNU Radio was installed around a month ago following the same procedure followed here, and the virtual sink/source blocks work just fine.Hi,Once I replace the virtual blocks with direct connections, things work just fine. What is the cause for this problem and how to fix it?
We recently bought a new PC with some powerful specs. GNU Radio was built from the source and it seems to be installed fine. However, when I try to use the virtual sink and source blocks in my flow graph, I am getting the following error:
Traceback (most recent call last):
File "./test_skh.py", line 595, in <module>
tb = test_skh()
File "./test_skh.py", line 486, in __init__
