It works perfectly when I use unity in ubuntu 14.04 but when I switch to i3 I receive this error message: > from numpy.linalg import lapack_lite, _umath_linalg > ImportError: libopenblas.so.0: cannot open shared object file: No such file or directory I am a newbie in i3 and I can't trace back this problem or relate it to i3 that why it's just happening there and not unity. I'd appreciate if I can have your suggestions.

Most likely it is some environment setting. Is `LD_LIBRARY_PATH` or `LD_RUN_PATH` set (differently) when using Unity?
