No module named conversion

[mcqrobot]

Hi,
I have installed all the need package of ROS and try to test it according to the "quick guide" :http://wg-perception.github.io/object_recognition_core/quickguide.html#quickguide.
it all goes well at the start ,however when I go to the step"Train Objects", it saids:
"Meshing objects can be done in a batch mode, assuming you are in the binary directory.
rosrun object_recognition_reconstruction mesh_object --all --visualize --commit"

1、firstly. I don't know the meaning of "binary directory", can you explain it. Thanks.
2、When I just run the command"rosrun object_recognition_reconstruction mesh_object --all --visualize --commit", it throw the error, the detail information is as follow:

mcq@mcq-ThinkPad-E520:~$ rosrun object_recognition_reconstruction mesh_object --all --visualize --commit
Traceback (most recent call last):
File "/opt/ros/indigo/lib/object_recognition_reconstruction/mesh_object", line 12, in
import ecto_image_pipeline.conversion
ImportError: No module named conversion

can you tell me how to reslove it.

Thanks very much , keeping waiting for your reply

Thx ! The code was usually used from source so that's why we never saw that bug. Please make sure you are using version 0.3.5. You can get it from shadow-fixed, thx.
I also fixed the doc, you did not need that binary folder detail.

@joy1314
you just change the file according to this website:0b031d5

if you can not find the file, you can use the command " locate [filename]" to find the file, for example, type the command in ternimal " locate apps/mesh_object ". if the result show you do not have the file , maybe it means it don't have installed the project from source, then you may need to install the project in types of source, while not in form of "PACAKGE".
you can follow this install guide :http://wg-perception.github.io/object_recognition_core/install.html#install

PS: install from ROS Package can not find the file and change them ,you must git clone from source and make for yourself
