Hi,
I'm trying to install the Windows binary of RDKit but having a
problem. After
from rdkit import Chem
I get
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
from rdkit import Chem
File "C:\RDKit_2012_03_1\rdkit\Chem\__init__.py", line 18, in <module>
from rdkit import rdBase
ImportError: DLL load failed: %1 is not a valid Win32 application.
I am using the Enthought Python distribution (EPD 7.0-2 32 bit python
2.7.1) on Windows 7 64 bit. I have the following environment variables:
PYTHONPATH %RDBASE%
RDBASE C:/RDKit_2012_03_1
Path ;%RDBASE%/lib; (amongst other things)
I'd be grateful for any suggestions as to what is going wrong and a
fix. Is the 64 bit OS an issue?
thanks,
Alan
Hi Alan,
It sounds like you are trying to load a 64-bit RDKit library in a 32-bit
Python environment. Is that the case ? The RDKit bitness must be the
same as the Python version you are using, which is 32-bit ("EPD 7.0-2
*32 bit python* 2.7.1").
Kind regards
