[Discuss-gnuradio] maximum recursion depth exceeded

[Yan Nie]

Dear all,

An runtime error came out when I run my python prgram:
File "/home/john/gnuradio/gr-iono/usrp_source_c.py", line 16, in __init__
    gr.io_signature(1,1,gr.sizeof_gr_complex))    #output signiture
  File "/usr/local/lib/python2.5/site-packages/gnuradio/gr/hier_block2.py", line 42, in __init__
    self._hb = hier_block2_swig(name, input_signature, output_signature)
RuntimeError: maximum recursion depth exceeded

I google this error, but didn't find any solution on this. How can this error be corrected?

Thanks for help.

Yan
