Install issues

[brad0taylor]

Thanks you for providing this awesome recipe. I'm having some issues with using the install and perhaps this is a good place to ask. (if not apologies) I've installed caffe as follows:

• conda create -n caffe
• conda install python=3.5
• conda install -c conda-forge caffe
• conda install caffe
• When I open python and run ">>>import caffe * " I get the following error.

ImportError: libprotobuf.so.12: cannot open shared object file: No such file or directory

I see /home/brad/anaconda3/envs/caffe/lib/libprotobuf.so.13 but not .so.12. Unfortunately I dont know to get the .12 version. Can you suggest a fix?

Thanks

[djsutherland]

I just got the same error; I suppose that protobuf needs to be pinned (conda-forge/conda-forge.github.io#411).

@brad0taylor, you should be able to work around this in the meantime with conda install protobuf=3.2.

[djsutherland]

Actually, it seems that this recipe is only built for python 2.7 for some reason, so @brad0taylor you're probably using the version of caffe from the default repositories. Same fix applies.

After I have the similar error on python3.5, I reinstall an environment for python2.7. But the error still remain.

And I do

conda install protobuf=3.2

But the error is still there. Plz help?

[djsutherland]

@shamangary, I think this should be fixed now if you conda install caffe=1.0.

I'm trying to to be able to run this demo https://github.com/ZheC/Realtime_Multi-Person_Pose_Estimation

I'm running ubuntu 14.04

I have installed Anaconda, and after installing many many many dependencies another one pops. It also requires python caffe

So I installed it with this command:
(I also tried Pip install caffe but if failed)
$ Conda install caffe
But then when I try to run it I get:

$ python
   >>> import caffe
   Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/home/gtkratosman-lap/anaconda2/lib/python2.7/site-packages/caffe/__init__.py", line 1, in

      File "/home/gtkratosman-lap/anaconda2/lib/python2.7/site-packages/caffe/pycaffe.py", line 13, in <module>

    ImportError: libprotobuf.so.12: cannot open shared object file: No such file or directory)
>>>

@salvador-blanco, make sure you're using the conda-forge version and don't have any partial pip-installed dependencies floating around. Easiest way is to make a new environment to test:

conda create -n caffetmp -c conda-forge caffe
source activate caffetmp
python -c 'import caffe'

If that works, it means something is messed up in your other environment, probably from mixing incompatible versions of packages from various sources.

[salvador-blanco]

conda install caffe=1.0
Did not work for me I still get the same error

[jakirkham]

Please share your full environment. Also please make sure you have protobuf 3.4 not 3.5.

[salvador-blanco]

So after doing

conda create -n caffetmp -c conda-forge caffe
source activate caffetmp
python -c 'import caffe'

I was able to use caffe on the caffetmp virtual environment, which means my other environments are messed up.
If I want to install caffe outside the environment how should I do it?
I have cleaned everything, so I can have a fresh start

[salvador-blanco]

I tried installing
conda install caffe
but I get the following error:

ERROR conda.core.link:_execute_actions(337): An error occurred while installing package 'defaults::opencv-3.1.0-np112py27_1'.
OSError(13, 'Permission denied')

I have no problem using

$python
>>>import cv2

the opencv version I have is 3.3.1

[jakirkham]

Sounds like some sort of conda problem. Could you please raise upstream? Also please make sure to give them enough info to work with. Thanks.

[jakirkham]

Closing as it appears the original issue has been resolved.

[nanodust]

indeed, clean caffe install w/ instructions above works.
yet - no luck w/ conda-forge caffe-gpu - same libprotobuf.so.12 error.

[jakirkham]

That's an unrelated issue, @nanodust.

and how can i fix this if there is something messed up in my environment without making new one?

Looks like I have found the solution.
Check your libprotobuf version:
conda list libprotobuf
if it's 3.4.0, you should downgrade it to 3.2.0
conda install libprotobuf=3.2.0
then try it again and it should be ok.

from ._caffe import Net, SGDSolver, NesterovSolver, AdaGradSolver,
ImportError: libprotobuf.so.10: cannot open shared object file: No such file or directory

Failing with conda install libprotobuf=3.2.0
conda install caffe=1.0

[getamu]

conda install caffe=1.0
@dougalsutherland
I am getting Packages NotFoundError: The following packages are not available from current channels:
I have done conda install libprotobuf=3.2.0

If you're installing caffe via conda and running into this, try:

conda install python=2.7 caffe-gpu protobuf gflags
