Import Error

Dear ObsPy users,

After finishing install the ObsPy to my MacOSX I follow the tutorial to filter a seismogram. I found an error when try to filter the trace using command

tr_filt.filter('lowpass', freq=1.0, corners=2, zerophase=True)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/wiwit/local/lib/python2.6/site-packages/obspy.core-0.4.8-py2.6.egg/obspy/core/", line 476, in new_func
    return func(*args, **kwargs)
  File "/Users/wiwit/local/lib/python2.6/site-packages/obspy.core-0.4.8-py2.6.egg/obspy/core/", line 1102, in filter
    raise ImportError(msg)
ImportError: Error during import from obspy.signal. Please make sure obspy.signal is installed properly.

May be some body can help me understand the problem and solve it ..

Great thanks,


Hello Wiwit,

I guess you just did not install obspy.signal. Install it in the same way you installed the other ObsPy modules and it should work.

Best wishes,


Thanks Lion,

It works now. :slight_smile:

Best regards,
