Hello

I have the following error running fcdp-tetra_demod.py

./170913/src/demod/python/fcdp-tetra_demod.py -D hw:1 -o /dev/stdout | ./170913/src/float_to_bits /dev/stdin /dev/stdout | ./170913/src/tetra-rx /dev/stdin Traceback (most recent call last): File "./170913/src/demod/python/fcdp-tetra_demod.py", line 5, in <module> from gnuradio import gr, gru, audio, eng_notation, blks2, optfir ImportError: cannot import name blks2

Gnuradio is 3.7.2 Liboscomore has been download from

git clone git://git.osmocom.org/libosmocore.git

no error in Gnuradio liboscomore , Tetra-rx installation

Saw that Gnuradio has different blocks structures and a programm to migrate from 3.6.51 to 3.7

Thanks for answer
