Install pybrain on python 3.2

Question

I'm trying to install pybrain on python 3.2. It says here: https://github.com/pybrain/pybrain/pull/85 that it should work. However it does not for me.

I tried:

$export PYTHONPATH=$PYTHONPATH:'/home/luis/Documents/pybrain/'https://github.com/pybrain/pybrain/pull/85

which works well for python 2.7.

Did somebody get it to work?

Answer 1

After hours of "what the hell?!"s I installed it. First the installer suggested is not updated for Python3 so I installed Distribute. With that installed I was able to use python setup.py install in the directory where I unrared pybrain. It gave a ton of errors. So I found this article (god bless google translate) and used 2to3 on pybrain directory. After I tried to install it again it gave an error on from string import split so I edited the file and removed that line (it is not needed really) and tried yet another time. This time no errors occurred and I was able to import pybrain without any problems. The same problem with the from string import split occurs in utilities.py again, so edit that line too.

I used 2to3 to turn examples to python3 too. benchmarkplots.py seems to work.

Update: pybrain now supports python3
Here's how to install if you run into trouble

pip install https://github.com/pybrain/pybrain/archive/0.3.3.zip

Or just grab latest github pybrain release.

I'm not sure what's wrong with icoz PyBrain port but for me it doesn't work at all. When training, error increases rather than decrease. I tried exact same code (copy-paste and fix compatibility issues) with python2 version and it worked as expected. Use with caution. – Cristicristian
