python can't import _caffe module

[rwhchan]

This is a slightly different problem from #263 so I've opened a new issue since that was closed.

Using cygwin, I tried the following

cmake (flags) ..
make all
make pycaffe

using the cmake procedure and generated _caffe.so, then did an export PYTHONPATH to the right directory (........../caffe/python), but Python (IDLE or IPython) doesn't recognize the file. I get the "no module named _caffe" (not "no module named caffe") error.

Does anyone know how to solve this? Thanks!

Is caffe being built properly? There should be a _caffe.so file (caffe/python/caffe/_caffe.so) corresponding to the compiled python package.

If you're using cygwin, are you trying to build it inside windows? Windows isn't officially supported, but some people have ported it (e.g. https://github.com/niuzhiheng/caffe).

[rwhchan]

Yes, the _caffe.so file is there, but Python doesn't read it even though I've added the folder to PYTHONPATH.

It's inside Windows, but the cygwin packages are being used.

What is your PYTHONPATH? A very common mistake is to add caffe/python/caffe, when caffe/python should be added instead.

[rwhchan]

It's caffe/python.

Are you sure _caffe.so is inside your caffe/python/caffe directory?
Just to confirm, make sure:

1. PYTHONPATH includes your caffe/python directory
2. caffe/python/caffe contains _caffe.so file.

The python interpreter should then be able to do import caffe successfully (assuming you have installed all other dependencies for the python caffe module).

Any update? I have the same problem here. _caffe.so is inside my /python/caffe folder but when I try to import the error described is returned.

PS: The compilation presented no errors (make all, make test, make runtest and make pycaffe).

EDIT: All requirements are ok:

My bash_profile file:

I have the same error. Are we all use anaconda? Is it only occurs with anaconda?
By the way, Anaconda don't use PYTHONPATH. Maybe this is the reason.
Any ideas?

export PYTHONPATH={Path2yourCaffe}/caffe/python:$PYTHONPATH

I don't think it has anything to do with Anaconda

Closing as this is an installation question; please using the mailing list.

From https://github.com/BVLC/caffe/blob/master/CONTRIBUTING.md:

Please do not post usage, installation, or modeling questions, or other requests for help to Issues.
Use the caffe-users list instead. This helps developers maintain a clear, uncluttered, and efficient view of the state of Caffe.

Rats, I have this same issue, is there a solution?

BESIDES
PAY ATTENTION!!!

export PYTHONPATH=/home/walegahaha/caffe/python:$PYTHONPATH
(though my 'caffe' is in /home, we also need to add '/walegahaha'[user name])

I have the same issue, and using anaconda. Any solutions? I don't have this problem without anaconda before.

This may a binary distribution problem.
