Dear all, This is only a small python import question. I think I'm right but just want some confirmation.
Previously I have installed numpy 1.5.1. and then I used pip install --upgrade numpy to install numpy 1.6.1 But when I try to import numpy as np within ipython shell, I still get the version 1.5.1 then I checked my sys.path: In [21]: sys.path Out[21]: ['', '/usr/local/bin', '/usr/local/lib/python2.7/dist-packages/pupynere-1.0.15-py2.7.egg', '/usr/lib/pymodules/python2.7', '/usr/local/lib/python2.7/dist-packages/scikits.statsmodels-0.3.1-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/Shapely-1.2.13-py2.7-linux-i686.egg', '/usr/local/lib/python2.7/dist-packages/pandas-0.7.3-py2.7-linux-i686.egg', '/home/chaoyue/python/python_lib', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/pymodules/python2.7/gtk-2.0', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.7/ubuntuone-client', '/usr/lib/pymodules/python2.7/ubuntuone-control-panel', '/usr/lib/pymodules/python2.7/ubuntuone-storage-protocol', '/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode', '/usr/local/lib/python2.7/dist-packages/IPython/extensions'] Actually I found I have numpy 1.5.1 in /usr/lib/pymodules/python2.7 and numpy 1.6.1 in /usr/local/lib/python2.7/dist-packages/numpy/ but because the first path is before the second one in sys.path, so ipython imports only the first one and ignore the second one. Then I delete the directory of /usr/lib/pymodules/python2.7/numpy and redo the import, I get the version 1.6.1 This means that import will try to find the first occurrence of the module and will ignore the ones with same name in later occurrences? cheers, Chao -- *********************************************************************************** Chao YUE Laboratoire des Sciences du Climat et de l'Environnement (LSCE-IPSL) UMR 1572 CEA-CNRS-UVSQ Batiment 712 - Pe 119 91191 GIF Sur YVETTE Cedex Tel: (33) 01 69 08 29 02; Fax:01.69.08.77.16 ************************************************************************************
