[Discuss-gnuradio] problem executing .py file

[bilal ghouri]

hello people,
i have successfully installed the RDS blocks in the gnuradio and when i try to execute any .py file which contains the RDS blocks, it is showing me the following error

Traceback (most recent call last):
  File "crc_fm_rds_tx.py", line 12, in <module>
    from gnuradio import gr, rds
  File "/usr/lib/python2.6/dist-packages/gnuradio/rds.py", line 7, in <module>
    import _rds
ImportError: dynamic module does not define init function (init_rds)

will be very thankful for the solution
regards
