Hi all, recently I tried to compile numpy/scipy with Python 2.5 and Intel C++ compiler 9.1. At first everything was fine, but the scipy test produced a few errors. The reason was a little difference: numpy svn(1.0.dev3233) with Intel C compiler (Python 2.5): ----------------------------------------------------------- In [1]:from numpy import ones, zeros, integer In [2]: In [2]:x = ones(1) In [3]:i = zeros(1, integer) In [4]:x[i] Out[4]:1.0 numpy svn(1.0.dev3233) with GCC 3.3 (Python 2.3): -------------------------------------------------- In [1]:from numpy import ones, zeros, integer In [2]: In [2]:x = ones(1) In [3]:i = zeros(1, integer) In [4]:print x[i] Out[4]:array([1]) The Intel version gives me a scalar whereas the gcc version an array. Maybe Python 2.5 is causing this problem but my first guess was the compiler. A typical error message from scipy.test(10): ====================================================================== ERROR: check_chebyc (scipy.special.tests.test_basic.test_chebyc) ---------------------------------------------------------------------- Traceback (most recent call last): File "[...]/lib/python2.5/site-packages/scipy/special/tests/test_basic.py", line 667, in check_chebyc C1 = chebyc(1) File "[...]/lib/python2.5/site-packages/scipy/special/orthogonal.py", line 461, in chebyc p = orthopoly1d(x,w,hn,kn,wfunc=lambda x: 1.0/sqrt(1-x*x/4.0),limits=(-2,2),monic=monic) File "[...]/lib/python2.5/site-packages/scipy/special/orthogonal.py", line 78, in __init__ equiv_weights = [weights[k] / wfunc(roots[k]) for k in range(len(roots))] TypeError: object of type 'numpy.complex128' has no len() Does anyone know how to resolve the problem?
