I am trying to compile a file namely usrp_spectrum_sense_tx.py but it says the following error message:
Traceback (most recent call last):
File "./usrp_spectrum_sense_tx.py", line 180, in <module>
from gnuradio import gr, gru, eng_notation, optfir, window
ImportError: cannot import name optfir
It is showing an ImportError. I need to sense the channel and send the data on the available channel. I have set my PYTHONPATH to dist-packages. Is there any specific mistake I am unable to see? Please suggest. Any help is appreciated.
Thank you,
Regards,
Dave
