@willyd Hi, here is the error log in the CmakeError.log:

Hi @PkuRainBow
I had a similar problem to you, so I thought I'd share my solution. My problem occurred because I was trying to use 32bit numpy with 64bit python27.

I got the same error messages as you in console: "The dependency target 'pycaffe' of target 'pytest' does not exist", as well as in the CmakeError.log: "Cannot open include file: 'pthread.h': No such file or directory" although I am building with VS not ninja like you.

It turns out that the problem was that I had the wrong version of numpy, so numpy was found (no error message) but failed to work properly. You can check this by running 'import numpy' in IDLE(python GUI), and seeing if it fails.

My solution:

  1. Delete numpy folder in: C:\Python27\Lib\site-packages
  2. Download the x64 numpy (unofficial) binaries in this site:
  3. Unzip and copy the contained numpy folder back to C:\Python27\Lib\site-packages
  4. Check that it works by running 'import numpy' in IDLE(python GUI)

Hope this helped. Maybe a flag to check correct numpy version would be a good idea? Numpy is only officially supported on 32bit so this error is probably going to come up again

I'm late here but with same problem. In my case, this problem is caused by boost's python library not found. Solved by specifying --with-python when compiling boost:

# cd path_to_boost
bjam.exe toolset=msvc-14.0 --build-type=complete address-model=64 --with-serialization --with-system --with-date_time --with-regex --with-filesystem --with-timer  --with-chrono  --with-program_options --with-thread --with-python --stagedir="test"

And also setting boost folder in Dependencies.cmake before find_package(Boost :

set(BOOST_ROOT "D:/lib/boost_1_58_0")
set(Boost_INCLUDE_DIR "D:/lib/boost_1_58_0/build/install/include/boost-1_58")
set(Boost_LIBRARIES "D:/lib/boost_1_58_0/test/lib")
set(BOOST_LIBRARYDIR "D:/lib/boost_1_58_0/test/lib")

Hi @zchrissirhcz
I followed your method to fix this issue during installing caffe on windows 10.
But It is showing same error after passing your steps.

Windows 10
Cuda 9.0
Boost 1.65.1

I couldn't add your line about Boost_INCLUDE_DIR, because there is no directory "build" after compile.
Please help me to fix this issue.
Thank you

@mahcinelearning2018 Do you mean there is no "build" directory after the compilation of boost? In fact, bjam or b2 will generate lib files in $BOOST_ROOT/bin.v2 and copy to $STAGE_DIR/lib, where $BOOST_ROOT is the directory of your extracted boost files, and $STAGE_DIR is $BOOST_DIR/stage by default, unless you specify it. In my example, I specify $STAGE_DIR to $BOOST_ROOT/test and will see $BOOST_ROOT/test/lib folder which containing these following files:

I hit same issue, and solved by executing 'python -m pip install numpy'.
