Hello list,
I tried to savetxt an array with ndim = 3, but I get an error:
In [252]: savetxt('test.dat',a)
/Library/Frameworks/Python.framework/Versions/6.2/lib/python2.6/site-packages/numpy/lib/io.py
in savetxt(fname, X, fmt, delimiter)
784
785 for row in X:
--> 786 fh.write(format % tuple(row) + '\n')
787
788 import re
TypeError: float argument required, not numpy.ndarray
I don't see this anywhere in the documentation of savetxt. And if that is a
restriction it should probably be caught with an assertion.
Numpy version 1.4.0.
I see why ndim>2 may cause problems, as there is now way on 'loadtxt' to
figure out the shape of the array, but I think it should throw an assertion
and the documentation should be updated.
Thanks, Mark
