Error running usrp_rx_cfile.py

GNU Radio

Hello everyone, I’m trying to capture a signal with the USRP board and
save
it into a file using the script usrp_rx_cfile.py. When I try to run the
script I get the following error:

File “./usrp_rx_cfile.py”, line 16, in
class my_graph(gr.flow_graph):
AttributeError: ‘module’ object has no attribute ‘flow_graph’

Can someone help me to solve it?

Thanks
