Dear Alps staff, I downloaded Alps in order to use the maximum entropy code for some analytic continuations, and wanted to start understanding it by using the script by Pruschke, found in a previous post, https://lists.phys.ethz.ch/pipermail/comp-phys-alps-users/2013/001978.html So after installing alps from source, using package alps-2.1.1-r6176-src-with-boost and following the instructions (I installed it on a linux machine with Ubuntu)... .. I performed the tutorial dmft-04-mott/tutorial4a.py, to produce a sample imaginary time Green's function data, and afterwards, from ipython, tried to follow some of the instructions of Pruschke's script, quoting from that script: "from pyalps.ngs import h5ar # hdf5 interface" this produced the error message:
/opt/alps/lib/pyalps/ngs.py in <module>() 29 import types 30 ---> 31 from pyngsparams_c import * 32 params.__bases__ = (MutableMapping, ) + params.__bases__ 33
ImportError: No module named pyngsparams_c And indeed I could not find any such module in the source. My question is: what is going on? Did I miss to install some pre-requisite? Note that the tutorial simulation for the hubbard model works fine till the end, same thing can be said for all tests which I ran before installing the code in its /opt/alps path. Thank you in advance for your help, Giovanni
