Perhaps a bug in the cmake detect which is part of boost, because I am not using python2 for caffe.
I used the path of least resistance because as far as I could tell boost only let you build one or the other and in my case it was the python3 boost api. In the end caffe was working and all the python3 tests with the Movidius SDK pass (which use python3). Jason. On 03/14/2018 09:50 AM, Burton, Ross wrote:
I thought that boost_python was the py2 binary, and boost_python3 was the py3 one? Is this not a bug in caffe?

The error that cmake returns doesn't even point to the fact that this is why the configuration fails. Example showing the problem with the missing symlink: ================ git clone https://github.com/weiliu89/caffe.git <https://github.com/weiliu89/caffe.git> cd caffe mkdir build cd build cmake -DBLAS=Open .. -- Configuring done CMake Error at CMakeLists.txt:85 (add_dependencies): The dependency target "pycaffe" of target "pytest" does not exist. ================ Conditionally creating the link when building python3 support into boost is all that is needed.
