Installation on Windows Using Prepackaged Modules

Python

Get and run the latest official Python 2.7.x installer from http://www.python.org/download/ (Python 3.x is NOT supported for now).

The Python binary and the Scripts directory should be set within the system PATH variable. Therefore append the following to the system PATH

;C:\path\to\Python2.7;C:\path\to\Python2.7\Scripts

See http://docs.python.org/using/windows.html#excursus-setting-environment-variables for a short tutorial on changing environment variables in Windows. Dependencies

1. Using pre-compiled executable installers are the easiest way to install the needed packages NumPy, SciPy and matplotlib.

   • The official 32-bit installers are available at:
     • http://sourceforge.net/projects/numpy/files/
     • http://sourceforge.net/projects/scipy/files/
     • http://sourceforge.net/projects/matplotlib/files/matplotlib/
   • or fetch the unofficial Windows 64 bit releases from http://www.lfd.uci.edu/~gohlke/pythonlibs/ (get the MKL builds for NumPy).

2. ObsPy and further dependencies can be downloaded via easy_install of the Distribute package. Download and run from the windows command line the Python script http://python-distribute.org/distribute_setup.py. You may also find the file in the ObsPy repository via https://svn.obspy.org/trunk/obspy.core/distribute_setup.py.

   python.exe distribute_setup.py

3. For obspy.xseed and obspy.arclink the Python module lxml is needed. Run from windows command line:

   easy_install lxml

4. We strongly recommend the enhanced Python shell IPython which can be obtained via:

   easy_install pyreadline
   easy_install ipython

ObsPy

For installing basic packages able to handle GSE2, SAC and MSEED files run on command line:

easy_install obspy.core
easy_install obspy.mseed
easy_install obspy.sac
easy_install obspy.gse2
easy_install obspy.imaging

Additional modules of ObsPy may be installed by calling easy_install followed by the module name.

easy_install obspy.signal
easy_install obspy.arclink
easy_install obspy.xseed
easy_install obspy.seishub
easy_install obspy.seisan
easy_install obspy.wav
easy_install obspy.sh
easy_install obspy.iris
easy_install obspy.neries
...

Installed packages may be updated at any time using the -U option, e.g.:

easy_install -U obspy.core
