PYTHONPATH to import caffe module

[sdemyanov]

In the tutorial it is written that "The module dir caffe/python/caffe should be installed in your PYTHONPATH for import caffe". However, when this path is added, a number of errors appear during the IPython initialization due to the confusion with internal io.py file. It seems like the actual path should be "caffe/python", in this case the initialization works well, and the "caffe" module can be correctly found.

Which tutorial says this? The installation instructions (http://caffe.berkeleyvision.org/installation.html) correctly suggest export PYTHONPATH=/path/to/caffe/python:$PYTHONPATH

It is on the interfaces page http://caffe.berkeleyvision.org/tutorial/interfaces.html

Thanks, I've made this more clear in de6d444 by using the same language as the installation page.
