Hello, I'm new to numpy, and considering using loadtxt() to read a data file. As a starter, I tried the example of the doc page ( http://docs.scipy.org/doc/numpy/reference/generated/numpy.loadtxt.html) :
from StringIO import StringIO # StringIO behaves like a file object c = StringIO("0 1\n2 3") np.loadtxt(c) I didn't get the expectd answer, but : Traceback (moste recent call last): File"(stdin)", line 1, in <module> File "C:\Python25\lib\sire-packages\numpy\core\numeric.py", line 725, in loadtxt X = array(X, dtype) ValueError: setting an array element with a sequence. I'm using verison 1.0.4 of numpy).
I got the same problem on a Ms-Windows and a Linux Machine. I could run the example by adding a \n at the end of c : c = StringIO("0 1\n2 3\n") Is it the normal and expected behaviour ? Bruno.

It's a bug that's been fixed. Numpy 1.0.4 is quite a bit out of date, so I'd recommend updating to the latest (1.3). Ryan -- Ryan May Graduate Research Assistant School of Meteorology University of Oklahoma
