Hi, i am running numpy on aix compiling with xlc. Revision 1.0rc2 works fine and passes all tests. But 1.0rc3 and more recent give the following on import: Warning: invalid value encountered in multiply Warning: invalid value encountered in multiply Warning: invalid value encountered in multiply Warning: invalid value encountered in add Warning: invalid value encountered in not_equal Warning: invalid value encountered in absolute Warning: invalid value encountered in less Warning: invalid value encountered in multiply Warning: invalid value encountered in multiply Warning: invalid value encountered in equal Warning: invalid value encountered in multiply Warning: invalid value encountered in multiply Warning: invalid value encountered in multiply Warning: invalid value encountered in add Warning: invalid value encountered in not_equal Warning: invalid value encountered in absolute Warning: invalid value encountered in less Warning: invalid value encountered in multiply Warning: invalid value encountered in multiply Warning: invalid value encountered in equal Warning: invalid value encountered in multiply Warning: invalid value encountered in multiply Warning: invalid value encountered in multiply [lots more of this] The odd thing is that all tests pass. I have looked, but can't find where this Warning is coming from in the code. Any thoughts on where this is coming from? What can I do to help debug this? I am not sure what revision introduced this issue. Thanks Brian ------------------------------------------------------------------------- Using Tomcat but need to do more?
