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\sirepackages\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 MsWindows 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 Numpy 1.0.4 is quite a bit out of date, so I'd recommend updating to the latest (1.3).
