Description (last modified by )
sage: from sage.interfaces.latte import count sage: P = Polyhedron(rays=[[1,0,0],[0,1,0],[0,0,1]]) sage: count(P.cdd_Vrepresentation(), ....: cdd=True, ....: multivariate_generating_function=True, ....: raw_output=True) --------------------------------------------------------------------------- IOError Traceback (most recent call last) <ipython-input-3-b8af61d0b5fe> in <module>() 2 cdd=True, 3 multivariate_generating_function=True, ----> 4 raw_output=True) /opt/sage/local/lib/python2.7/site-packages/sage/interfaces/latte.pyc in count(arg, ehrhart_polynomial, multivariate_generating_function, raw_output, verbose, **kwds) 170 return R(ans) 171 elif multivariate_generating_function: --> 172 with open(filename + '.rat') as f: 173 ans = f.read() 174 if raw_output: IOError: [Errno 2] No such file or directory: '/home/vincent/.sage/temp/mangouste/6180/tmp_NYOKC8.rat'
Actually, LattE produces an error message with this example but the return value is 0
This is LattE integrale 1.7.3 Available from http://www.math.ucdavis.edu/~latte Invocation: count --multivariate-generating-function '--redundancy-check=none' --cdd /home/vincent/.sage/temp/mangouste/6027/tmp_yXiTqU Warning: Not performing check for empty polytope, because it is unimplemented for the CDD-style input format. size = 4 x 4 Number Type = rational Computing vertices and edges with cddlib...size = 4 x 4 Number Type = rational done. Reading .ext file... readCddExtFile:: Given polyhedron is unbounded!!!(2)
