[obspy-users] OBSPY and PyInstaller

Hello again,

I copied the "obspy" directory from C:\Python27\Lib\site-packages\ to my 
"dist" directory, and this solved the import problem...to an extent. The 
runtime now finds functions such as readSEGY, which I have imported as:

from obspy.segy.core import readSEGY

however functions such as detrend, which are called as member functions 
of a Stream variable, cause the following error:

   File "C:\Python27\Lib\site-packages\obspy\core\stream.py", line 2105, 
in detrend
   File "C:\Python27\Lib\site-packages\obspy\core\trace.py", line 1619, 
in detrend
     func = _getFunctionFromEntryPoint('detrend', type)
   File "C:\Python27\Lib\site-packages\obspy\core\util\base.py", line 
343, in _getFunctionFromEntryPoint
     raise ImportError(msg % (group.capitalize()))
ImportError: Your current ObsPy installation does not support any 
Detrend functions. Please make sure SciPy is installed properly.

I suspect that this error is similar to my original one, i.e. the 
required obspy modules have not been converted to .pyd files in the 
correct way.
