Hi, I build gr-osmocom + XTRX again. And compile successfully
But when I run osmocom_fft :


osmocom_fft -F -f 850e6 -s 4e6
> Traceback (most recent call last):
>   File "/usr/local/bin/osmocom_fft", line 23, in <module>
>     import osmosdr
> ModuleNotFoundError: No module named 'osmosdr'
>


clone gr-osmosdr from https://github.com/osmocom/gr-osmosdr
 Try master and gr-3.8 branch, get the same result

gnuradio-config-info -v
