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 -
Reading package lists... Done
Building dependency tree
Reading state information... Done
python-scipy is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
What should I do?
Try to install it as a python package using pip. You said you already tried:
sudo apt-get install python-scipy
Now run:
pip install scipy
I ran both and it worked on my Debian-based box.
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 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.
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
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
If you need to get scipy
in your Python environment on Windows you can get the *.whl files here:
https://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
Remember that you need to install numpy+mkl
before you can install scipy
.
https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
When you have downloaded the correct *.whl files just open a command prompt in the download directory and run pip install *.whl
.
对于 Windows 用户: pip install -U 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.
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
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
Your python don't know where you installed scipy. add the scipy path to PYTHONPATH
and I hope it will solve your problem.
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.
使用sudo pip install scipy
安装库,因此以后不能请求权限
in previous steps by @user5747799, it do not work directly but instead change the URL ( https://bootstrap.pypa.io/pip/2.7/get-pip.py ) and now spicy work very well on Ubuntu 20.04
Also o follow steps to switch between version from https://www.fosslinux.com/39384/switching-between-python-2-and-3-versions-on-ubuntu-20-04.htm
To install pip using alternative URL:
$ wget https://bootstrap.pypa.io/pip/2.7/get-pip.py
$ sudo python2 get-pip.py.2 # for python 2.7 (or verify the result of previous step)
$ 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
in order to verify
$ python
then
>>> import scipy
with no errors to show.
for Mac run below command to install scipy
$ brew install scipy
$ pip install scipy
Try forcing a reinstall of scipy:
python3 -m pip install scipy --force-reinstall
for python3 below command to install scipy
python3 -m pip install scipy
