ValueError for numpy when importing KDTree from scipy.spatial
I'm getting an odd behavior when I try to load KDTree. In the interactive interpreter: the first time I try to load it, it gives me an error. Second time works fine. When trying to run from command line, same error. To reproduce, just type the 4 commands below. If people can't reproduce it, I might do a re-install. Here's my session. *** Python 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)] on win32. ***

No problem here. What are your numpy/scipy versions? Do you have scipy compiled against the numpy that you are using? If you use numpy 1.4.0rc1 with scipy 0.7.1, then it might be the cython incompatibility problem. Josef

Delete the old numpy install and reinstall. I ran into the same problem. Chuck
