I forgot to mention that a temporary fix is just to set the environment variable ALPS_XML_PATH pointing to the ALPS_ROOT/lib/xml directory.

Assuing you have Conda in $HOME/Miniconda, this would be export ALPS_XML_PATH=$HOME/Miniconda/lib/xml

Unfortunately the Mac build got stuck because of time limits on the CI servers and the Boost package just got a new version that seems to break dependent libraries, hence it might take more than expected for the actual fixes to propagate.

Thanks for the quick response! Indeed, I did have np111py27_blas_openblas_1 installed, and I am using OSX.

Best wishes, Larry

Dear Larry,

Which version of ALPS did you install? (just type conda list alps)

I know the problem, but I think/hope I just solved it two days ago. Unfortunately the Conda-Forge builds are currently overwhelmed and I see that the Mac release still didn’t make it in the queue. You basically need this build to start and finish successfully: https://travis-ci.org/conda-forge/alps-feedstock/builds/193304343

My guess is that you now have np111py27_blas_openblas_0 or np111py27_blas_openblas_1, whereas the bug has been resolved in np111py27_blas_openblas_2.

Best, Michele

Dear ALPS list,

I was very excited to see that the new version of ALPS was available for installation via conda! I did the conda installation, and I attempted to run the simple simulation pasted at the bottom of this email (taken from the ALPS webpage). The code started to execute, and the input files were created (parm1.in.xml, parm1.task1.in.xml, parm1.task2.in.xml, parm1.task3.in.xml). Then the message "parsing task files ..." was immediately followed by the message "XML tag expected". Each of the four XML input files start with the following two lines:

<?xml version="1.0" encoding="UTF-8"?>

<?xml-stylesheet type="text/xsl" href="ALPS.xsl"?>

I'm sure that there must be a very simple cause for this problem. Can anyone diagnose this for me?

Thanks! Larry

CODE:

import pyalps

parms = []

for t in [1.5,2,2.5]:

parms.append(

   {

     'LATTICE'        : "square lattice",

     'T'              : t,

     'J'              : 1 ,

     'THERMALIZATION' : 1000,

     'SWEEPS'         : 100000,

     'UPDATE'         : "cluster",

     'MODEL'          : "Ising",

     'L'              : 8

   }

)

input_file = pyalps.writeInputFiles('parm1',parms)

pyalps.runApplication('spinmc',input_file,Tmin=5),writexml=True)
