Unable to import caffe

Question

I executed make pycaffe in the caffe directory and it worked fine. I also did this:

gsamaras@gsamaras-A15:~/caffe/python$ export PYTHONPATH=$PYTHONPATH:/home/gsamaras/caffe/python

but when I try to import caffe in another project, I get this:

ImportError: No module named caffe

How to fix this?

Also note that in the Makefile.config of caffe, there is this line:

PYTHON_INCLUDE := /usr/include/python2.7 \ <-- correct
/usr/lib/python2.7/dist-packages/numpy/core/include <-- doesn't exist

My numpy version is 1.11.

Relevant:

Edit:

I found this, which suggests pip install -U scikit-image, but it fails with:

  Running setup.py (path:/tmp/pip_build_root/scikit-image/setup.py) egg_info for package scikit-image

    return working_set.find(moduleOrReq) or require(str(moduleOrReq))[0]

and now I am getting this error:

ImportError: No module named skimage.io

sudo apt-get install python-skimage worked for me.

I had to use sudo apt-get install -U scikit-image after all! The reason is: Didn't work with pip, but worked with apt-get?

I encountered similar error in my caffe installation when I try to import skimage.io. However, when I tried to install the skimage via pip, it fails with the same message posted above.

Then I tried using apt-get to install scikit-image. It finished successfully. Unfortunately, it installed outdated version which cause another error in my code.

Finally, I have found a workaround by first installing virtualenv and fresh installing those libraries (scikit-image, scipy, matplotlib, etc) using pip. My caffe now worked flawlessly. Hope this helps other in the same situation.

Yeah I heard about `virtualenv` too, thanks mitbal! Thanks for upvoting my question, since you find it useful! — gsamaras, Jun 28 '16 at 13:00
