I have gnuradio version 3.6.2-13-g65ea256f

Q1 : In the directory */usr/local/share/gnuradio/examples/digital/ofdm* I
tried to run ofdm_mod_demod_test.py
but it threw the error * 'module' object has no attribute
I tried to locate ofdm_bpsk_mapper but couldn't find it in my system
I remember it was running last year 

Rest of all the files are running fine i.e. benchmark_tx.py, rx.py etc 

Q2 : I was running the *uhd_tx_ofdm.grc* example from the gr_apps

When I run it , I get the error *'module' object has no attribute

*File "/usr/local/lib/python2.6/dist-packages/gnuradio/blks2impl/ofdm.py",
line 97, in __init__
self._pkt_input = gr.ofdm_mapper_bcv(rotated_const, msgq_limit,
AttributeError: 'module' object has no attribute 'ofdm_mapper_bcv'*

I tried to locate ofdm_mapper_bcv and got it in the include path 


Q3 : There is another folder of ofdm inside *gnuradio/examples/ofdm* apart
from *gnuradio/examples/digital/ofdm*
There also I am facing errors like :

*ofdm_mod_demod_test.py  ----   'module' object has no attribute
benchmark_ofdm.py ---- 'module' object has no attribute 'ofdm_mapper_bcv'
benchmark_tx.py ---- 'module' object has no attribute 'ofdm_mapper_bcv'*

Is it my improper installation or some files/modules have been depreciated
in the new version !!
