The problem is that your vispython finds the installed ALPS libraries in ALPS and not the ones in VisTrails. You can either download the updated version of ALPS from the web, or run vispython from the C:\Program Files\Vistrails\vistrails directory.

Dear Prof. Troyer,
As you pointed out, I found I mistakenly ran the tutorial using another Python 2.6 (not the one contained in Vistrails directory). Sorry for that!
As another try, I ran the vispython.bat in C:\Program Files\ALPS\bin, and I got an error "The specified procedure could not be found." Opening vispython.bat by notepad, I found the followings:
"IF EXIST %HOMEDRIVE%"Program Files"\VisTrails\vistrails %HOMEDRIVE%"Program Files"\VisTrails\vistrails\Python25\python.exe IF EXIST %HOMEDRIVE%"Program Files (x86)"\VisTrails\vistrails %HOMEDRIVE%"Program Files (x86)"\VisTrails\vistrails\Python25\python.exe"
I thought maybe "Python25" should be replaced by "Python26", so I made the change, and the vispython was loaded properly. But when I entered "import pyalps" again, the error remains:
"Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Program Files\Vistrails\vistrails\Python26\lib\site-packages\pyalps__init__.py", line 29, in <module> from tools import * File "C:\Program Files\Vistrails\vistrails\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:\Program Files\Vistrails\vistrails\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."
When I ran the tutorial in ALPS by python.exe contained in C:\Program Files\Vistrails\vistrals\Python26, this error still occurs.
I don't know what is missing, I'm eager to hear your advices. Thanks a lot!
Best,
Bolun

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,
