python3+ 与 python-dateutil1.5（仅支持python2+）

[hawklucky]

when i import caffe in python，this is the problem

File "/home/××/caffe-master/venv/lib/python3.5/site-packages/dateutil/rrule.py", line 55
raise ValueError, "Can't create weekday with n == 0"

but the /python/require.txt declare the python-dateutil must >1.4 <2 version,
i don't sure if i change python-dateutil form ver1.5 to ver2.0, is it ok?

I had same issue, and fixed by installing python-dateutil ver2.0+ (actually 2.5.3).
Seems working well.

Shouldn't this be open until we have a working requirements.txt for Python 3?

I am using Python3.5 come this issue too. @mecab Just wanna ask why I can't find python-util-2.5.3, it seems python-util-2.0 is the latest version. It still have this problem when I upgrade to python-util-2.0.

sudo pip3 install --upgrade python-util
