Lapsack libraries not found

Issue #40 new
Former user created an issue

Hi,

I received a long list of error messages when I tried to install numpy on my Windows machine with git, including Atlas libraries not found, Blas libraries not found, Lapack libraries not found...

Does anyone know what went wrong? I followed the exact installing instructions...

Thanks!

    These are just warnings and/or merely informational messages. None of those libraries are required, though they speed up some operations in numpy.linalg. You probably installed numpy correctly. Have you checked that you can import and use it?

    No it still told me: no module named numpy...

    Don't know if it helps but below are all the messages I received installing numpy:

    Ah, thanks, the actual error is down at the end of the log. Can you install the latest PyPy release (2.6.1) and try again? We aren't compatible with PyPy 2.5.1 any more.
