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/util.py", 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/trace.py", line 1102, in filter
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 ..
