Can you give me more details? Was the binary built on a machine with an absent ATLAS? Show me the output of ldd on _dotblas.so with both ATLAS installed and not. Can you import numpy.core._dotblas explicitly under both? -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
