what is your "fcn.data_dir"

[iamGavinZhou]

hi, i cloned your repository, but there are some problems, have you tested your code?
i used pip to install on my pc, using commond "pip install fcn"
followed your instruction, first i should convert caffe model to chainer model, with "./scripts/caffe_to_chainermodel.py ", but i got some wrong message
`/usr/local/lib/python2.7/dist-packages/matplotlib/font_manager.py:273: UserWarning: Matplotlib is building the font cache using fc-list. This may take a moment.
warnings.warn('Matplotlib is building the font cache using fc-list. This may take a moment.')
/usr/local/lib/python2.7/dist-packages/matplotlib/init.py:1350: UserWarning: This call to matplotlib.use() has no effect
because the backend has already been chosen;

or matplotlib.backends is imported for the first time.

warnings.warn(_use_error_msg)

`
it sounds the "fcn.data_dir" is "/usr/local/lib/python2.7/dist-packages/fcn/_data/"
but when i use ipython to debug this problem. In first console window, i typed "import fcn; fcn.data_dir", i got the answer "/home/work-station/zx/fcn/data"; But when i opened another console window, i got an answer "/usr/local/lib/python2.7/dist-packages/fcn/_data", it doesn't make sense

what should i do now, thanks

To use ./scripts/caffe_to_chainermodel.py, you need to follow the instruction for developers https://github.com/wkentaro/fcn#for-developers.

i used it! but it doesn't works

[wkentaro]

what was the error?

[iamGavinZhou]

same as the first one, about the "fcn.data_dir"
it's all right in your PC?

[wkentaro]

On my pc it says like below:

% ./scripts/caffe_to_chainermodel.py
'/usr/local/lib/python2.7/dist-packages/fcn-3.1.0-py2.7.egg/fcn/_data/fcn8s_from_caffe.chainermodel' is already newest version.

[wkentaro]

For the answer to your question, I usually use python setup.py develop with virtualenv, so fcn.data_dir is always ~/fcn/data.
But if you install fcn with command pip or python setup.py install, it is /usr/local/lib/python2.7/fcn/_data or ~/.local/lib/python2.7/fcn/_data.

Fixed?
