Dear all,
In an attempt to get to grips with ALPS 2, I've ran the example from example/parapack/exchange directory. When compiled and run from the command line, it produces both xml and hdf output files:

Then I'm trying to load the simulation results using python tools, and that's where I seem to hit a snag. I follow the tutorial at http://alps.comp-phys.org/mediawiki/index.php/ALPS_using_Python#Loading_the_simulation_results, here's the exact script:
br@ymir:~/sweethome/adatoms/par_temp/parapack_example$ cat readin.py #!/usr/bin/python import pyalps import matplotlib.pyplot as plt import pyalps.plot
result_files = pyalps.getResultFiles(prefix='params-ising') print result_files obslist=pyalps.loadObservableList(result_files)
This fails with the following error message:
br@ymir:~/sweethome/adatoms/par_temp/parapack_example$ ./readin.py ['./params-ising.task1.out.xml'] Traceback (most recent call last): File "./readin.py", line 8, in <module> obslist=pyalps.loadObservableList(result_files) File "/home/br/ALPS2/lib/pyalps/load.py", line 611, in loadObservableList res = ll.GetProperties(files,proppath,respath,verbose=verbose) File "/home/br/ALPS2/lib/pyalps/load.py", line 126, in GetProperties fs = self.GetFileNames(flist) File "/home/br/ALPS2/lib/pyalps/load.py", line 108, in GetFileNames log( "FILE ", f, "DOES NOT EXIST!") TypeError: log() takes exactly 1 argument (3 given)
Running the same sequence of commands in alpspython interpreter produces the same error message. From what I can see, there are two issues here: 1) GetFileNames() function of the Hdf5Loader class does not handle the replica#.h5 file endings. 2) there's a problem with log() function which the interpreter reports,
Or am I doing something wrong here? Or, more to the point, how do I load the simulation results into python?
Thanks in advance,
Zhenya
