I'll take a look. As a quick fix, can you try what the comment in the error message tells and just comment out that line?

I tried, but there are more imports missing, like the "*_impl" classes.

Thanks, Tommy

Hi,

I am the maintainer for  the VisTrails binaries. I am trying to update the bundled ALPS, but the win64 version found here fails: http://archive.comp-phys.org/software/vistrails/alps-vistrails-2.1.1-win64.z...

This is the error:

packages\pyalps\ngs.py", line 61, in <module>     from pyngsobservable_c import createRealObservable #remove this with new ALEA! ImportError: cannot import name createRealObservable

Looking at the dates, it looks like some of the files are old. The dates in the win32 binaries are newer, and that binary works. Is the win64 binary broken, or have I made an error somewhere?

Thanks, Tommy
