How do I install pybrain?

I downloaded pybrain using git 

$ git clone git://github.com/pybrain/pybrain.git

and when i tried to install,

$ python setup.py install

this threw an error while installing scipy:

Running scipy-0.14.0/setup.py -q bdist_egg --dist-dir /tmp/easy_install-fxe0wp/scipy-0.14.0/egg-dist-tmp-Kbnkhx

ImportError: No module named numpy.distutils.core

I tried to install other modules, but I came across almost the same problem. Can you explain how I can solve this?

Since you downloaded it, you can also use pip to install the install

pip install -e /local/path/to/pybrain

This way pip can install dependencies for you.

Some systems have very old pips / setuptools, so you may need

pip install --upgrade pip
pip install --upgrade setuptools

if the first one fails (I've seen it happen on some systems) try



python -m pip install --upgrade pip

(you will need write permissions to the required installation paths).

edit: it turns out this is not trivial to install ... I tried the following sequence

pip install numpy
pip install scipy
pip install pybrain

in the new virtualenv on Ubuntu 12.04 LTS and scipy complained about the missing BLAS environment variable ... I know BLAS is a library for statistics or math, but not much more.

Reading at http://www.scipy.org/install.html it seems like apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose

scipy can be installed (if you are on the correct Ubuntu versions that I am not ..)

I recommend using PIP to install modules like this:

pip install pybrain

But if you can't use that or don't choose, try using @thebjorn



Hope this helped,

I'm not sure, but maybe you should install numpy?

pip install numpy

Just install the following command from the command line:

`pip install pybrain`

You can download this script: ez_setup.py

and run in a shell $ python ez_setup.py

also you can use the tool easy_install

:

$ easy_install scipy
