ImportError: No module named caffe

[Taran Dhillon]

Hi All. I have followed all the instructions, installed caffe and all dependencies correctly but i am receiving this error. Any help would be much appreciated.

ImportError                               Traceback (most recent call last)

ImportError: No module named caffe

I found your post while trying to install deepdream, because I was having the same problem.

I felt like a complete idiot when I figured out what I missed.

in editing my .bashrc, for PYTHONPATH, I missed the replacing of USERNAME with my actual username. Doh!

export PYTHONPATH="${PYTHONPATH}:/home/USERNAME/caffe/python"

Might not be your problem, but was mine. The next thing I hit was:
No module named skimage.io

Which is supposedly fixed with:

pip install -U scikit-image

...which is running at this time, and seems to take a while to complete. I'll keep you posted if you like.

[Papa Roux]

OK all good now. I did actually need to sudo the pip install. Other than than, I am now dreaming! Good luck!

[T]

Thanks for your response. All good now!

I've made a script that does the whole installation process for Debian if you would like a copy?

[BadChimpStew]

I would love to check out your script!

The script contains 3 files, as follows:

1. Download and install Anaconda from https://store.continuum.io/cshop/anaconda/

2. Place Makefile.config and dp.sh in ~/Downloads type in "./dp.sh"

3. Run "export PYTHONPATH=/home/USERID/Downloads/caffe-master/python:$PYTHONPATH"

4. Run "sudo python /home/USERID/Downloads/caffe-master/scripts/download_model_binary.py /home/USERID/Downloads/caffe-master/models/bvlc_googlenet/"

5. Run "cd deepdream-master/"

6. Run "ipython notebook ./dream.ipynb"

7. Change the following:

"model_path = '../caffe/models/bvlc_googlenet/' # substitute your path here" TO model_path = '/home/USERID/Downloads/caffe-master/models/bvlc_googlenet/' # substitute your path here

Hello Everyone! I am new to caffe. I am trying to install it in ubuntu 14.04 which is running as a dual boot on my macbook pro. I managed to get it running initially but soon after my laptop crashed, following which I have the same error "No module named caffe" I have followed the instructions to the letter and it seems to be an issue with opencv. I get an error message while compiling caffe which I have copied below.

/usr/bin/ld: cannot find -lopencv_imgcodecs
collect2: error: ld returned 1 exit status
make: *** [.build_release/lib/libcaffe.so.1.0.0-rc3] Error 1

This leads me to believe there is something wrong with my OpenCV installation? Would really appreciate some help!

[Chan Kim]

Did you try 'make pycaffe' in the caffe directory after making caffe? (This makes caffe exposed to python)

[Jan]

I think opencv_imgcodecs is only present in OpenCV 3.x, not in OpenCV 2.x. I compiled current caffe just yesterday on Ubuntu 14.04 with OpenCV 3.1 using the cmake building method. I am not sure which version is required currently/whether you can set it in the Makefile.config
