Caffe: Cannot install caffe with Python interface by CMake

[jamesweb1]

Issue summary

I try to install caffe on my Mac, but it cannot install Python interface cause Not find BOOST and Doxygen. The output of CMake as follows:

Steps to reproduce

mkdir build
cd build
cmake ..

Tried solutions

brew uninstall --ignore-dependencies boost boost-python
brew install --build-from-source -vd boost boost-python
and try again

System configuration

• Operating system: Mac OS 10.12.6
• Compiler: CMake
• BLAS: Yes (vecLib)
• Python version (if using pycaffe): 2.7.10

Can you try downgrading Boost to 1.66? It is quite likely that CMake does not find libboost_python, since the naming convention has been changed in Boost 1.67:

[srbnghosh99]

install anaconda and then add the anaconda path in makefile.configure

[xiaojinghu]

Run into the same problem. Did you solve this?

I tried this by downgrading Boost to 1.65 (cmake -DCPU_ONLY=ON -DBOOST_ROOT=/usr/local/Cellar/boost/1.65.1 .. ), but still the same error (The dependency target "pycaffe" of target "pytest" does not exist) comes up.

@xiaojinghu @jamesweb1 Have you guys been able to solve this Boost finding issue? I've been stuck on this problem for many days

[triple-tam]

Update from me: CMake finds Boost and Doxygen, but the

-- Python interface is disabled or not all required dependencies found. Building without it...
and
The dependency target "pycaffe" of target "pytest" does not exist.

still occur. If anyone knows how to resolve this, it would be greatly appreciated.

python 2.7 works, see this article: https://medium.com/@buffaloal/build-caffe-with-anaconda-on-macos-1070a8d0a9fe

[taosean]

create a soft link libboost_python.so for libboost_python27.so.* or libboost_python34*.

[taosean]

For Python interface is disabled or not all required dependencies found. Building without it..., I used this command and it solved this problem.
cmake -D BLAS=open -D PYTHON_EXECUTABLE=~/Develop/Anaconda2/setup/bin/python -D PYTHON_INCLUDE_DIR=~/Develop/Anaconda2/setup/include/python2.7/ -D PYTHON_PACKAGES_PATH=/home/taoxuan/Develop/Anaconda2/setup/lib/python2.7/site-packages/ -D PYTHON_LIBRARY=/home/taoxuan/Develop/Anaconda2/setup/lib/libpython2.7.so ..

Same problem here, but I think it DOES have something to do with the version of libboost_python

[mas2tg]

Did anybody was able to fix this? I am not using (and I don't want to use) conda.
EDIT: the error actually went away by installing libboost_python3 (with brew). I guess I was getting this error since my python was defaulted to v3.xx instead of v2.xx ...

Hello, what command have you used?
