I am using Python 2.7 and trying to get PyBrain to work.
But I get this error even though scipy is installed -
Traceback (most recent call last):

from scipy import reshape, dot, outer
ImportError: No module named scipy
I have installed scipy using this command -
sudo apt-get install python-scipy
I get -

python-scipy is already the newest version.

What should I do?

For windows users:
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

Once finish installation, 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.]
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.

>>>import scipy
Use sudo pip install scipy
to install the library so It cannot ask for permissions later
Try to install it as a python package using pip as follows
$ sudo apt-get install python-scipy
If you want to run a python 3.x script, install scipy by:
$ pip3 install scipy
Otherwise install it by:
$ pip install scipy
If you need to get scipy
in your Pyhton environment on Windows you can get the *.whl files here:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
Remember that you need to install numpy+mkl
before you can install scipy
.
http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
When you have downloaded the correct *.whl files just open a cmd prompt in the download directory and run pip install *.whl
.
To ensure easy and correct installation for python use pip from the get go
To install pip:
$ wget https://bootstrap.pypa.io/get-pip.py
$ sudo python2 get-pip.py # for python 2.7
$ sudo python3 get-pip.py # for python 3.x
To install scipy using pip:
$ pip2 install scipy # for python 2.7
$ pip3 install scipy # for python 3.x
For Windows User : pip install -U scipy
I had a same problem because I installed both of python2.7 and python3. when I run program with python3 I received same error. I install scipy with this command and problem has been solved:
sudo apt-get install python3-scipy
I recommend you to remove scipy via
apt-get purge scipy
and then to install it by
pip install scipy
If you do both then you might confuse you deb package manager due to possibly differing versions.
My problem was that I spelt one of the libraries wrongly when installing with pip3, which ended up all the other downloaded libaries in the same command not being installed. Just run pip3 install on them again and they should be installed from their cache.
Your python don't know where you installed scipy. add the scipy path to PYTHONPATH
and I hope it will solve your problem.
This may be too basic (and perhaps assumable), but -
Fedora users can use:
sudo dnf install python-scipy
and then (For python3.x):
pip3 install scipy
or (For python2.7):
pip2 install scipy
