It is possible that you have a linking problem with _dotblas.so. On some
systems, such a problem will only manifest itself at run-time, not build-time.
At runtime, you will get an ImportError, which we catch because that's also the
error one gets if the _dotblas is legitimately absent.
Try importing _dotblas by itself to see the error message.
In : from numpy.core import _dotblas
Most likely you are missing the appropriate libblas, too, since you don't
