Import caffe error

Question

i compiled caffe successfully in my ubuntu machine but cannot import in python.

Caffe is installed /home/pbu/Desktop/caffe

i tried adding the /home/pbu/caffe/python path to sys.path.append, still not working

i am trying to import caffe

root@pbu-OptiPlex-740-Enhanced:/home/pbu/Desktop# python ./caffe/output.py
Traceback (most recent call last):
  File "./caffe/output.py", line 13, in <module>
    import caffe
  File "/home/pbu/Desktop/caffe/python/caffe/__init__.py", line 1, in <module>
    from .pycaffe import Net, SGDSolver
  File "/home/pbu/Desktop/caffe/python/caffe/pycaffe.py", line 10, in <module>
    from ._caffe import Net, SGDSolver
ImportError: No module named _caffe

Probably already solved, but the path you say you added to the path is different from the one where you say Caffe is installed. — Mark, Mar 10 '15 at 15:34
Also, the path caffe expects is different from the usual default. Check that? — shaunakde, Apr 10 '15 at 20:58

This happens when you have not run make for the python files separately.

Run make pycaffe soon after running make in the Caffe directory.

You may have to set the path to the python library correctly in Makefile.config

Adding to the above best answer. After you run make for python files by running make pycaffe where you ran your previous makes. Then you have to export that python path by running export PYTHONPATH=<path-to-caffe>/python. You can choose to run this everytime before running a python code which utilizes caffe or add it to your ~/.bashrc.

Well, I use the cmake-gui for making Caffe. There you need to set the Python paths to the Anaconda-python:

PYTHON_EXECUTABLE <path_to_anaconda_home>/bin/python2.7
PYTHON_INCLUDE_DIRECTORY <path_to_anaconda_home>/include/PYTHON2.7
PYTHON_LIBRARY <path_to_anaconda_home>/lib/libpython2.7.so

You should build caffe and pycaffe using the command:

cd $FRCN_ROOT/caffe-fast-rcnn
make -j8 && make pycaffe

and before the compilation, you should create a Makefile.config file and set the corresponding library path, such as python.

More details are presented on the web: bgirshick/py-faster-rcnn.

What's more, when I run the "Beyond the demo" section, it seams that if I Create a symlink of the folder "VOCdevkit" as "VOCdevkit2007" which turns out to be "can't find the dataset". So, I change the folder name as "VOCdevkit2007", and it runs well.

this answer is quite specific to the "faster RCNN" implementation — Shai, Nov 22 '16 at 06:10

I posted my Caffe install notes (my architecture: Arch Linux x86_64 | Intel i7 CPU ...) in an Anaconda Python 2.7 virtual environment here:

I also encountered the (downstream) "Import caffe error," for which I needed to resolve my $PYTHONPATH to complete the make compilation and get Caffe finally installed, and also to be able to import it (in Python).
