@shixudongleo thanks for the note, I fixed it. Based on your fork, it looks like you got everything installed! That's great to see.

thanks for the script. Till line 67, everything went fine. Since I am using anaconda python, what would be the change in script. ( I tried but it threw me an error)

Instead of ln'ing /usr/local/cuda/.. you could just set the flag in Makefile.config to:
CUDA_DIR := /Developer/NVIDIA/CUDA-8.0/ right?


doctorpangloss commented Sep 20, 2016

@TimZaman That could work! Definitely try it. It's an annoying step for sure and pollutes brew.

This was very helpfull albeit I never got it compiling using CUDA 7.5 and Xcode 7.3 because of vecLib compile errors. Had no problem compiling without CUDA though 😄
In the end I still had to rename _caffe.dylib to in the python package to use caffe in python, which seems weird given this PR BVLC/caffe@a14f0ef


doctorpangloss commented Nov 9, 2016

@jrimestad re: CUDA 7.5 and Xcode 7.3, definitely upgrade to El Capitan / Sierra if you can and use CUDA 8.0. If you're using a Hackintosh, I can confirm that Sierra with a Titan X (and probably all Maxwell chips) work fine. Allegedly the new drivers that ship with the CUDA installation package support Pascal, but it's untested on my end.

Re: renaming _caffe.dylib, yep, just pretty much ignore what other people say, they basically never follow their own steps on clean machines, so files are found in all sorts of places and they think stuff works when it really does not. Also, I believe this does not use CMAKE, while that PR does.

It's unusual that you should get vecLib compile errors. On both my Sierra and El Capitan stations I have vecLib in the right places. I corrected the installation instructions for Sierra though (it was essentially untested until now).

Hi, when I ran make -j8 all, I got following errors"
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [.build_release/lib/] Error

Please help. Thank you.

in case where cudnn library is a tgz file, run
sudo tar -xvzf ~/Downloads/cudnn-8.0-osx-x64-v5.0-ga.tgz -C /Developer/NVIDIA/CUDA-8.0/
instead of
sudo tar -xvf ~/Downloads/cudnn-8.0-osx-x64-v5.0-ga.tar /Developer/NVIDIA/CUDA-8.0/

Thank you so much for this guide!
Here are some other errors and solutions I encountered:

  1. make pytest doesn’t work!! Veclib issue:
    “ld: framework not found vecLib”
    Solved by reinstalling xcode command line tools

  2. import caffe doesn’t work! Due to a Malloc error. This is a leveldb issue.

Also posted this in my own blog:

humphd commented Dec 20, 2016

Thank you for this, it really helped me. I found that doing this on 10.12.2 required me to downgrade boost to 1.55 vs. 1.59 as mentioned above, or else make pycaffe always failed.

humphd commented Dec 20, 2016

I also found that the version of protobuf used by brew and pip was breaking caffe at runtime (e.g., make pytest failing with crazy errors reading protobufs and __init__ got an unexpected keyword argument 'syntax' for every unit test). I found that I needed to uninstall/re-install an explicit version of protobuf as described in tensorflow/tensorflow#11 (comment), specifically I did:

$ brew uninstall protobuf
$ pip uninstall protobuf
$ pip install 'protobuf>=3.0.0a3'

7ayden commented Dec 29, 2016

I was so glad for the caffe easy installation gospel, yet there are tons of error occurring. However, I tried
$ brew uninstall protobuf
$ pip uninstall protobuf
$ pip install 'protobuf>=3.0.0a3'
then bash it.
and it shows ImportError: No module named caffe

BirkhoffLee commented Jan 8, 2017

Thanks for the tutorial! I've successfully built Caffe, used 2 days to figure out.

Has anyone used MKL as the math library, I can't seem to link it properly

alejandroposada commented Apr 11, 2017

When I run python -c 'import caffe I get:

Traceback (most recent call last):
File "", line 1, in
File "/Users/alejandroposada/Library/Python/2.7/lib/python/site-packages/caffe/", line 1, in

ImportError: dlopen(/Users/alejandroposada/Library/Python/2.7/lib/python/site-packages/caffe/, 2): Library not loaded: .5.dylib
Referenced from: /usr/local/lib/
Reason: image not found

How can I solve this?
(make -j8 pytest 's result is OK)

I got

Liams-MBP:caffe lca$ brew install hdf5 opencv
Error: No available formula with the name "hdf5"

until I did brew tap homebrew/science

Also homebrew/versions is now deprecated

make: *** No rule to make target `all'. Stop.

I get this after running make -j8 all. Please help. Thank you !

If someone needs to run this version of caffe:
I've followed this guide and it works. Just make sure that:

  • hdf5 version = 1.10.1
  • protobuf version = 3.2.0_1

because brew downloads updated dependencies for those two

My MacBook's GPU is Intel Iris Graphics 6100, not cuda-based, so cannot run caffe with GPU on my mac? And there is no need to install cuda toolkit?

chengsam commented Sep 15, 2017

@ShivaliGoel Run the command in the caffe directory, i.e. cd caffe
