Hello, read your code, don't know how to use your code is, oneself also in the study of FCN,Specific how to use the code.than you for you research!

Do you have question about the scripts in README.rst? It won't work?

How do you install this package? python setup.py develop? python setup.py install? or pip install fcn?

jinhang commented 8 years ago

my command : python setup.py install

jinhang commented 8 years ago

What should I do now? thanks

jinhang commented 8 years ago

I'm not understand about here：

You need to download pascal VOC2012 dataset from `here <http://host.robots.ox.ac.uk/pascal/VOC/voc2012/>`_,
and install it as below construction::

  - fcn - data - pascal - VOC2012 -- JPEGImages
                                   - SegmentationClass
                                   - ...

I'm not understand about here：

It means you should install VOC2012 dataset to the data directory.

wkentaro commented 8 years ago

my command : python setup.py install

wkentaro commented 8 years ago

Fixed on my PC. Please try following instruction. https://github.com/wkentaro/fcn#for-beginners

You need to install latest fcn (fcn==3.1.0).

wkentaro commented 8 years ago

@jinhang Is this fixed?

wkentaro commented 8 years ago

Can i close this?

jinhang commented 8 years ago

hi, "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." i don't understand your fcn.data_dir? you say the virtualenv,but how to use it?

jinhang commented 8 years ago 
git clone https://github.com/wkentaro/fcn.git
cd fcn

python setup.py install
fcn_install_trained_data.py

python setup.py install and your python setup.py develop .what is this difference? because it also can not run.so ,can you give me a new tutorial ? thanks wkentaro so much!

wkentaro commented 8 years ago

i don't understand your fcn.data_dir?

It is defined here. https://github.com/wkentaro/fcn/blob/master/fcn/__init__.py#L11

you say the virtualenv,but how to use it?

If you are not familiar with virtualenv, maybe you don't have to use it.

hi ,can you tell me the what is APC2015 dataset? I want use FCN model to detection in other dadaset?

wkentaro commented 8 years ago

APC2015 dataset?

That is Amazon Picking Chalenge 2015. http://amazonpickingchallenge.org/2015/index.shtml The dataset is collected by myself and published as described here: https://github.com/wkentaro/fcn/tree/master/examples/apc2015/dataset

thank you very much!
