Installation of Theano.

I am learning Deep learning, the first thing to do is to install Theano. This is the process:
1.
 go to the link: http://deeplearning.net/software/theano/install.html#install 

2.
 I get this error: dfftpack missing fortran complier. I download the gfortran pkg for mac. install gfortran

 3. run sudo pip install Theano
now it is running for gfortran...
but still has a lot of errors.

4. then I get a lot of erros saying missing dependencies of scipy

5. run the command sudo port install py27-numpy +atlas py27-scipy +atlas py27-pip 

but I get these two errors:

Error: org.macports.build for port llvm-3.3 returned: command execution failed
Error: Failed to install llvm-3.3

6.
run sudo port install llvm-2.9 



==================================
alright, so I failed on installing it on mac, spending the whole afternoon on ubuntu 12.04.

1. install libblas, liblapack from the software center.
2. install scipy using command  python setup.py install --user this install the scipy to my local user .
3. install numpy similarly.
4. install python nose from software center.
5. then I can test numpy using python -c "import numpy;  numpy.test()"  to get the following output:

NumPy version 1.7.0
NumPy is installed in /fs/narahomes/wenhoujx/.local/lib/python2.7/site-packages/numpy
Python version 2.7.3 (default, Aug  1 2012, 05:14:39) [GCC 4.6.3]
nose version 1.1.2

6. test scipy using python -c "import scipy; scipy.test()"    the output:

  warnings.warn(depdoc, DeprecationWarning)

7. now install theano, download from https://pypi.python.org/pypi/Theano#downloads

then tar, python setup.py install --user

8. test theano 

wenhoujx@narawks16:/scratch0/pylib$ python -c "import theano; theano.test()"
Theano version 0.6.0rc3
theano is installed in /fs/narahomes/wenhoujx/.local/lib/python2.7/site-packages/Theano-0.6.0rc3-py2.7.egg/theano

----------------------------------------------------------------------
Ran 0 tests in 0.002s

OK

there is a problem that the test doesn't run . zero test.

9. pip uninstall theano    to clear theano
then pip install --user theano to install it in $HOME.
then run python -c "import theano; theano.test()"
now everything is running, but with warnings.

it will probably take ~30min, it is 9:24pm now.
finish on 10:31 pm

10. done.
