pycaffe error: "ImportError: No module named skimage.io"

[Daniel Orf]

Setup:  Ubuntu 14.04 x64, CUDA 6.5, NVIDIA GTX970, ATLAS for BLAS

I've run into this error when attempting to run "import caffe" in python (script and command line).  This happens in Anaconda Python and standard Python v2.7.8 - i made a fresh install of everything including the OS (Ubuntu 14.04) to rerun on standard Python v2.7.8 to the same result.    The error output after "import caffe" is below.  I've had zero luck tracking down "skimage.io" import error.  It should be noted that I was able to "make pycaffe" successfully.  I first ran into this issue when trying out the mnist example - which I was able to train successfully, I just ran into this error when attempting to run "classify.py".

I would also like to point out that the caffe install page explicitly says not to add ~/caffe/python/caffe to your PYTHONPATH while the Interfaces page explicitly says to add this directory to your PYTHONPATH.  What gives?

with PYTHONPATH of /home/danielo/caffe/python

 Thanks everyone.

Are you trying to run something from the caffe/python/caffe directory? That can cause this error, because caffe has a module called io, which conflicts with skimage's own module called io.

What it says on the interfaces page is wrong or at least misleading (and should be clarified); caffe/python is the directory which should appear in your PYTHONPATH, not caffe/python/caffe.

I get different errors depending on whether the PYTHONPATH includes "~/caffe/python/caffe" or not (see the two different sets of errors in my first post), but it always ends with "ImportError: No module named skimage.io" regardless of the PYTHONPATH.

Thanks,

Dan

Indeed. Those were meant as disjoint statements; regardless of your PYTHONPATH, you can get errors of this type if your _working directory_ is caffe/python/caffe, so you might check that.

Good point.  Ran it again at a couple different working directories, and I get the same error regardless of working directory.

Hi Daniel

Any luck solving this? I'm having the same issue myself.

pip install -U scikit-image

This should solve your problem.

in the installation steps there was a requirements.txt file which has all the requirements of python. Install that. That should solve all the python related issues.

@Aman Verma   I have same problem . you have solved it ?

If you read closely, you will see that you're supposed to add to your PYTHONPATH=/path/to/caffe/python:$PYTHONPATH NOT  PYTHONPATH=/path/to/caffe/python/caffe:$PYTHONPATH.

That is the difference. And that should solve your problems.

If there are any other import errors, make sure you have installed all Python modules listed in caffe/python/requirements.txt

Cheers,

Phil

From: 
http://scikit-image.org/docs/dev/install.html

i got  caffe locally set up for DIGITS in my python path, 
when i run the digits dev-server it no longer complains about unable to import caffe. the problem was just skimage.io
so i have to install scikit-image:

for debian/ubuntu:
sudo apt-get install python-skimage

now digits runs properly and is running on port 5000 and i can see in browser

Hi, thank you. Your method solved my problem. Would you mind explain the difference between "sudo apt-get install python-skimage" and "sudo pip install scikit-image"? The later one doesn't work for me.

Same here. The reason is that apt-get will install patched dependencies, I asked a question on this, check it for more.
