Install problems on Windows 7

[tgefell]

I'm on a new computer with Windows 7.

I've installed the 32 bit versions of python-2.7.1 and all subsequent requirements.

pandas-0.3.0.win32-py2.7.exe does not complete. It just stops and windows claims it is not responding. The same phenomenon happened installing tables-2.2.1.win32-py2.7.exe. I'm assuming that pytables is recommended but not required for pandas. Anyway, both of these installs do not work.

Suggestions?

So both PyTables and pandas hang when you try running the binary installers? Interesting. Could you also ask Francesc Alted (the PyTables developer) about it? I don't really have any suggestions.

You could install MinGW and compile pandas from source yourself, follow these instructions:

http://docs.cython.org/src/tutorial/appendix.html

Could you try that and let me know if that works?

I will see if I can get a Windows 7 VM set up to try to reproduce what you're seeing...

I'm trying Francesc Alted first.

Since I'm moving from XP and python 2.6 to Windows 7 and python 2.7, I might try backing out all of the 2.7 stuff and going through the whole process for 2.6. At least that way I can determine if it's a Windows 7 issue or a 2.7 issue. I will hold off on the compilation option until last because I don't have a great deal of confidence in my doing that sort of thing yet.

Francesc has not done a build on Windows 7, so he had no immediate input.

Most of the comments that I've seen about installation problems for PyTables have to do with HDF5. Does pandas use that library?

Another thing that is different between my Windows XP boxes running python 2.6 (all running pandas successfully) and my new Windows 7 box running python 2.7 is in the registry. The XP boxes all have a \Python entry in the Registry: HK_LOCAL_MACHINE\Software\Python\PythonCore\2.6\InstallPath
and another:
HK_LOCAL_MACHINE\Software\Python\PythonCore\2.6\PythonPath

Does the pandas installation on Windows reference anything in the HK_LOCAL_MACHINE section of the registry?

pandas does not require PyTables and HDF5 is not part of the install process. So there must be some distutils problem.

You might consider obtaining a copy of the Enthought Python Distribution-- it's all set up to easily build Python packages from source. It also comes bundled with pytables. You literally will be able to type:

easy_install -U pandas

and it will install.
