What is the easiest way to install BLAS and LAPACK for scipy?

Question

I would like to run a programme that someone else has prepared and it includes scipy. I have tried to install scipy with

pip install scipy 

but it gives me a long error. I know there are ways with Anaconda and Canopy but I think these are long ways. I would like to have a short way. I have also tried

I have also tried

pip install lapack 

with this result

Collecting lapack   Could not find a version that satisfies the requirement lapack (from versions  ) No matching distribution found for lapack 

I have also tried

pip install blas 

with similar results

G:\determinator_Oskar>pip install blas Collecting blas   Could not find a version that satisfies the requirement blas (from versions: )  No matching distribution found for blas 

Why does a scipy get so complicated ?

Answer 1

For Debian Jessie and Stretch installing the following packages resolves the issue:

sudo apt install libblas3 liblapack3 liblapack-dev libblas-dev 

---

Your next issue is very likely going to be a missing Fortran compiler, resolve this by installing it like this:

sudo apt install gfortran 

---

If you want an optimized scipy, you can also install the optional libatlas-base-dev package:

sudo apt install libatlas-base-dev 

Source

---

If you have any issue with a missing Python.h file like this:

Python.h: No such file or directory

Then have a look at this post: https://stackoverflow.com/a/21530768/209532

Answer 2

The SciPy installation page already recommends several ways of installing python with SciPy already included, such as WinPython.

Another way is to use wheels (a built-package format):

pip install SomePackage-1.0-py2.py3-none-any.whl 

The wheel packages you can find on: http://www.lfd.uci.edu/~gohlke/pythonlibs/

For SciPy you need:

• the NumPy wheel packages
• and the SciPy wheel packages
