Hi, I think this worked some time ago, but I cannot tell for sure: In [19]:numpy.__version__ Out[19]:'0.9.5.1980' In [20]:numpy.array([1,1], dtype=[('f1', 'i8'),('f2','i4')]) --------------------------------------------------------------------------- exceptions.TypeError Traceback (most recent call last) /home/faltet/<ipython console> TypeError: expected a readable buffer object Sorry, I cannot check with latest SVN because it segfaults. --
