Hi Bolun Chen

I am confused by your reference to C:\Python26\lib\site-packages\pyalps\tools.py below. ALPS does not install anything into that location.

Did that problem occur when running the tutorial from Vistrails or from the shell using vispython?

Hi All,

I am a beginner to ALPS and I want to use it to perform QMC. I have downloaded and installed the Vistrails 1.5, the ALPS 2.0b3 and ALPS Vistrails extensions on Windows. But when I ran the tutorial using Python 2.65 contained in the Vistrails, I got an error, which read,

"Traceback (most recent call last): File "<stdin>", line 1, in <module> File ,\lib\site-packages\pyalps__init__.py", line 29, in <module> from tools import * File "C:\Python26\lib\site-packages\pyalps\tools.py", line 39, in <module> from pyalps.pytools import convert2xml, hdf5_name_encode, hdf5_name_decode, rng File "C:\Python26\lib\site-packages\pyalps\pytools.py", line 28, in <module> from pytools_c import * ImportError: DLL load failed: The specified module could not be found."

Can someone help me to tackle this problem? Thanks very much!

Best,

Bolun Chen
