How do I install SciPy on my system?
Update 1: for the NumPy part (that SciPy depends on) there is actually an installer for 64 bit Windows: numpy-1.3.0.win-amd64-py2.6.msi (is direct download URL, 2310144 bytes).
Running the SciPy superpack installer results in this message in a dialog box:
"Cannot install. Python version 2.6 required, which was not found in the registry."
I already have Python 2.6.2 installed (and a working Django installation in it), but I don't know about any Registry story.
The registry entries seems to already exist:
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Python]
[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore]
[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6]
[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\Help]
[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\Help\Main Python Documentation]
@="D:\\Python262\\Doc\\python262.chm"
[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\InstallPath]
@="D:\\Python262\\"
[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\InstallPath\InstallGroup]
@="Python 2.6"
[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\Modules]
[HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\PythonPath]
@="D:\\Python262\\Lib;D:\\Python262\\DLLs;D:\\Python262\\Lib\\lib-tk"
What I have done so far:
Step 1
Downloaded the NumPy superpack installer numpy-1.3.0rc2-win32-superpack-python2.6.exe (direct download URL, 4782592 bytes). Running this installer resulted in the same message, "Cannot install. Python version 2.6 required, which was not found in the registry.". Update: there is actually an installer for NumPy that works - see beginning of the question.
Step 2
Tried to install NumPy in another way. Downloaded the zip package numpy-1.3.0rc2.zip (direct download URL, 2404011 bytes), extracted the zip file in a normal way to a temporary directory, D:\temp7\numpy-1.3.0rc2 (where setup.py and README.txt is). I then opened a command line window and:
d:
cd D:\temp7\numpy-1.3.0rc2
setup.py install
This ran for a long time and also included use of cl.exe (part of Visual Studio). Here is a nearly 5000 lines long transcript (230 KB).
This seemed to work. I can now do this in Python:
import numpy as np
np.random.random(10)
with this result:
array([ 0.35667511, 0.56099423, 0.38423629, 0.09733172, 0.81560421,
0.18813222, 0.10566666, 0.84968066, 0.79472597, 0.30997724])
Step 3
Downloaded the SciPy superpack installer, scipy-0.7.1rc3- win32-superpack-python2.6.exe (direct download URL, 45597175 bytes). Running this installer resulted in the message listed in the beginning
Step 4
Tried to install SciPy in another way. Downloaded the zip package scipy-0.7.1rc3.zip (direct download URL, 5506562 bytes), extracted the zip file in a normal way to a temporary directory, D:\temp7\scipy-0.7.1 (where setup.py and README.txt is). I then opened a command line window and:
d:
cd D:\temp7\scipy-0.7.1
setup.py install
This did not achieve much - here is a transcript (about 95 lines).
And it fails:
>>> import scipy as sp2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named scipy
Platform: Python 2.6.2 installed in directory D:\Python262, Windows XP 64 bit SP2, 8 GB RAM, Visual Studio 2008 Professional Edition installed.
The startup screen of the installed Python is:
