“No module named scipy” on Windows

Question

In sklearn\\base.py, I have the statement from scipy import sparse . I am getting this error "no module named scipy" .

I tried to install using pip install scipy , but I get so many errors:

libraries mkl_rt not found
openblas not found
lapack not found
no lapacl/blas resources found

etc.

What should I do on Windows ?

Answer 1

I found this solution after days.

Firstly which python version you want to install?

If you want for Python 2.7 version:

STEP 1:

scipy‑0.19.0‑cp27‑cp27m‑win32.whl

scipy‑0.19.0‑cp27‑cp27m‑win_amd64.whl

numpy‑1.11.3+mkl‑cp27‑cp27m‑win32.whl

numpy‑1.11.3+mkl‑cp27‑cp27m‑win_amd64.whl

If you want for Python 3.4 version:

scipy‑0.19.0‑cp34‑cp34m‑win32.whl

scipy‑0.19.0‑cp34‑cp34m‑win_amd64.whl

numpy‑1.11.3+mkl‑cp34‑cp34m‑win32.whl

numpy‑1.11.3+mkl‑cp34‑cp34m‑win_amd64.whl

If you want for Python 3.5 version:

scipy‑0.19.0‑cp35‑cp35m‑win32.whl

scipy‑0.19.0‑cp35‑cp35m‑win_amd64.whl

numpy‑1.11.3+mkl‑cp35‑cp35m‑win32.whl

numpy‑1.11.3+mkl‑cp35‑cp35m‑win_amd64.whl

If you want for Python 3.6 version:

scipy‑0.19.0‑cp36‑cp36m‑win32.whl

scipy‑0.19.0‑cp36‑cp36m‑win_amd64.whl

numpy‑1.11.3+mkl‑cp36‑cp36m‑win32.whl

numpy‑1.11.3+mkl‑cp36‑cp36m‑win_amd64.whl

Link: click

Once the download finished, go to your directory.

For example my directory:

cd C:\Users\asus\AppData\Local\Programs\Python\Python35\Scripts>
pip install [where/is/your/downloaded/scipy_whl.]

After that installation

STEP 2:

Numpy+MKL

From same web site based on python version again:

After that use same thing again in Script folder

cd C:\Users\asus\AppData\Local\Programs\Python\Python35\Scripts>

pip3 install [where/is/your/downloaded/numpy_whl.]

And test it in python folder.

Python35>python
Python 3.5.2 (v3.5.2:4def2a2901a5, Jun 25 2016, 22:18:55) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import scipy

Answer 2

Download the scipy wheel file from the following link

https://pypi.python.org/pypi/scipy

Then do pip install with the Downloaded file

pip install <wheel-file>

if required , provide sudo permission

Answer 3

I face same problem when install Scipy under ubuntu. I had to use command:

$ sudo apt-get install libatlas-base-dev gfortran
$ sudo pip install scipy

on CentOS

$ yum install lapack-devel
$ sudo pip install scipy

Answer 4

numpy should be installed before installing scipy . I face this issue when I was running only with numpy . First install numpy and then install scipy . It worked for me.

pip install numpy

pip install scipy

It will display a message like this.

Requirement already satisfied: numpy>=1.8.2 in (from scipy)

Hope this would be helpful. :)

Answer 5

I have never successfully pip'd a scipy install, instead I have found it easier to install all the base dependencies. Check here for your OS

I've never tried this on windows, but the linux installs have always worked for me.
