Scipy output error :undefined symbol: sgegv_

Question

When I tried running keras examples, the program output an error,

/usr/local/lib/python2.7/dist-packages/scipy/linalg/lapack.py in <module>()
    354 from .blas import find_best_blas_type as find_best_lapack_type
    355 
--> 356 from scipy.linalg import _flapack
    357 try:
    358     from scipy.linalg import _clapack

ImportError: /usr/local/lib/python2.7/dist-packages/scipy/linalg/_flapack.so: undefined symbol: sgegv_

Anyone knows how to solve it?

what OS? How did you install scipy? Any errors during the installation? — cel, Nov 29 '15 at 16:57
Also, which BLAS are you using? Have you manually compiled/installed LAPACK? — Daniel Renshaw, Nov 29 '15 at 17:12
@cel Ubuntu14.04. I tried using pip and binary code. No errors, but some warnings seems not important. — Chao Ding, Nov 30 '15 at 20:17
@DanielRenshaw Hi! That's latest BLAS and LAPACK manually compiled/installed. — Chao Ding, Dec 01 '15 at 01:21

No need to downgrade your lapack. It is better to upgrade your scipy

pip install git+https://github.com/scipy/scipy.git

**Do this.** Newer LAPACK is a good. Obsolete SciPy, however, is a bad. – Cecil Curry Aug 28 '16 at 07:17

In lapack 3.6.0 some deprecated functions which are used in scipy were dropped. You have to use lapack 3.5.0 or lower in order to get things to work back.
