hdf5, python and h5py for windows 64 bit

· Uncategorized

(I’m assuming python 2.76 version here. Make the relevant changes, if different)

1. First install python 64 bit version

2. Apparently, the installer doesn’t register the python installation as 64 bit installation in the registry. You’ll need to “clone” the  registry entry [HKEY_LOCAL_MACHINE\SOFTWARE\Python] into [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python]. Create a registry file “python_276.reg” with the text below and execute it:

Windows Registry Editor Version 5.00





[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\2.7\Help\Main Python Documentation]


@=”Python 2.7″



3. Install the 64 bit version of h5py from Christoph Gohlke Unofficial Windows Binaries (Thanks a lot Christoph!)


Test it:

from Python command line:

>>> import h5p 

Nothing happened? good 🙂
