Hello,
I have been trying to get PyInstaller to package a program that uses ObsPy.
A short test program is copied below. The program fails on the readSEGY
line, due to an import error. When I use ArchiveViewer to look at the .pyz
archive then all of the obspy routines are listed.
If I copy the obspy directory from C:\Python27\Lib\site-packages\ to my
dist directory then the readSEGY line succeeds, so it looks like something
has gone wrong in the packaging process. The st.detrend line stills fails,
and although the final error mentions SciPy I think the problem is still
related to the packaging.
I presume I need to convert the obspy .pyc files to .pyd files with the
directory slashes replaced with dots, e.g. obs\core\util\base.pyc would be
obs.core.util.base.pyd, but I'm unsure how this is done (yep, I have read
the manual).
Any help is much appreciated,
Ra
Test program (note I have installed obspy as an executable from PyPI):
import numpy as np
# None of these help:
import obspy
import obspy.core
import obspy.core.stream
# This is required (and it works fine):
from obspy.segy.core import readSEGY
def test():
# readSEGY works if obspy directory copied from site-packages:
st = readSEGY('data.sgy')
print st[0]
print np.mean(st[0])
# .detrend does not work in compiled version:
st.detrend()
print np.mean(st[0])
if __name__ == "__main__":
test()
