Scipy installation issue, getting ImportError: libopenblas.so.0: cannot open shared object file or directory

Question

I am installing Scipy-0.16.1 on Ubuntu 14.04

OpenBLAS_0.2.18 and Numpy-1.11.0 have been installed with no issues.

Scipy-0.16.1.tar.gz has been downloaded

site.cfg was copied and un-commented the following lines:

[openblas]

libraries = openblas

library_dirs = /opt/OpenBLAS/lib

include_dirs = /opt/OpenBLAS/include

Added a line to ~/.bashrc

export LD_LIBRARY_PATH=/opt/OpenBLAS/lib:$LD_LIBRARY_PATH

source ~/.bashrc

ldconfig

sudo python setup.py config

ERROR

ImportError: libopenblas.so.0: cannot open shared object file: No such file or directory

Solution 1

You have to install OpenBlas system library. Try:

sudo apt-get install libopenblas-dev

Solution 2

Firstly, try locate libopenblas.so.0 to find out the path.

Then, do echo $LD_LIBRARY_PATH to check if it has been included.

try export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH before run setup.py

[Francesco Nazzaro]

or you can try to install scipy with pip install scipy==0.16.1

I tried export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH and run sudo python setup.py config , it still shows same error

[Francesco Nazzaro]

try to install with pip

[Admin]

I tried pip install scipy and get Requirement already satisfied (use --upgrad to upgrade): script in /usr/lib/python2.7/dist-packages

[Francesco Nazzaro]

it seems that you already have scipy installed. try to open a python shell and try import scipy

[Jacques MALAPRADE]

In centos use: dnf install openblas-devel
