Hi, I am getting the following error ImportError: cannot import name channels... when I run a python script. I added the following line to a code from gnuradio import channels First I made a simulation model using gnuradio-companion and started making changes to the top_block.py code.. Basically I want to add a fading channel model to my simulation and cant find a fading channel model block which has a doppler shift variable in gnuradio-companion. So I am trying to add it by editing the code. How can I fix this error. If I comment out the line "from gnuradio import channel" I get the following errors Error: failed to enable realtime scheduling USing Volk machine: sse3_64_orc Traceback(most recent call last): File "top_block.py~", line 127, in <module> tb= top_block() File "top_block.py~" , line 69, in_init_ self.gr_fading_model=gr.fading_model( AttributeError: 'module' object has no attribute 'fading model' I am using Vsphere client to log onto a server and use virtual ubuntu. Thanks.
