"can't set attribute" error

[donnut]

I've install iepy on an arch linux machine in a fresh conda environment. There are no problems during installation with pip install iepy

However, if I try to run iepy there is an error message

Traceback (most recent call last):

Any idea what might be wrong?

Hi donnut.

It seems that nltk version we are requiring is not playing well with python3.5 as discussed in here https://github.com/nltk/nltk/issues/1106

Will try to fix our dependencies within these days to fix that (easy to do, very slow to test and need to find the time for that), since there is a nltk release that shall be working.

If you are in hurry (and also want to give me a hand testing things) you can clone the repo, patch requirements (setup.py) and try to install it from there.

[donnut]

I try to get it working and let you know.

[donnut]

BTW, how do you want to change the deps? Downgrade nltk, or python?

[jmansilla]

If you have a python3.4 at hand, use it and you shall be able to install iepy with it.

What we would like to do in a near future is to fix our dependencies (upgrade nltk) in order to allow python3.5

[donnut]

Got it.

[ToferC]

+1 for this issue. Running Linux Ubuntu mate with the latest build of Anaconda (3.5). Ran

$conda create -n iepy python=3.4

and it worked just fine.

[j0hn]

We have Python 3.5 support on our branch development now. Will be included in the next release.

I am facing the same issue in OSX when I try to create a iepy project:

Then I tried to upgrade, both sklearn and nltk and I both modules work correctly... probably the versions of other modules for this framework need to be updated.

Any idea of how to proceed?...

[jmansilla]

Did you try using the development branch? Can you?

[alonsopg]

Apparently, it worked with the development branch:

[jmansilla]

Good to know Alonso.

I'll try to make a release with development branch within these days.

[jmansilla]

Release just published.
