Re: [Numpy-discussion] Problem with loadtxt

Thanks Warren, that does solve the problem. I am still confused however by this: In [42]: c = StringIO("5399354557888517120") In [43]: np.loadtxt(c, dtype=np.uint64) Out[43]: array(5399354557888517120L, dtype=uint64) Does the above seem contradictory to you? Thanks, Scott On Tue, Aug 17, 2010

Yes, concatenate is doing other work under the covers. In short, in supports concatenating a list of arbitrary python sequences into an array and does checking on each element of the tuple to ensure it is valid to concatenate. On Tue, Aug 17, 2010 at 9:03 AM, Zbyszek Szmek wrote: > Hi, > this is
