python - 编译Boost.Numpy时CMake错误 "NumPy import failure"

Question

这是我按照描述安装的 here :

1. Python 3.5 (Anaconda3 2.4.3)
    Chainer 1.5.0.2
    Cython 0.23.4
    NumPy 1.10.1
    tqdm
2. OpenCV 3.0.0
3. lmdb 0.87
4. Boost 1.59.0

接下来我要编译并安装 Boost.NumPy。一开始，NumPy模块找不到。经过一番搜索，我在~/anaconda3/lib/python3.5/site-packages/numpy/core/include/numpy中找到了NumPy相关的文件。而不是类似 /usr/lib , /usr/local/lib等等。因此，在/Boost.NumPy/CMakeList.txt中，我添加了这一行:

set(NUMPY_INCLUDE_DIRS, /home/graphics/anaconda3/lib/python3.5/site-packages)

但是 NumPy 仍然找不到。我运行 cmake -DPYTHON_LIBRARY=$HOME/anaconda3/lib/libpython3.5m.so ../ 时发生错误生成 Boost.NumPy 的 makefile。这是错误:

graphics@gubuntu:~/usr/Boost.NumPy/build$ sudo cmake -DPYTHON_LIBRARY=$HOME/anaconda3/lib/libpython3.5m.so ../

CMake Error at libs/numpy/cmake/FindNumPy.cmake:61 (message):

Call Stack (most recent call first):

-- Configuring incomplete, errors occurred!

我尝试替换 NUMPY_INCLUDE_DIRS与其他一些目录，但没有任何作用。我应该写什么给CMakelists.txt告诉 cmake 在哪里找到 NumPy 模块并导入它？

提前致谢!

可能需要找出问题所在的其他文件:

1. CMakeLists.txt Boost.NumPy。

Answer 1

终于可以用了!但我不知道为什么...:(

我做了什么:

1.  I reinstalled numpy to /usr/lib/python3.5/site-packages (previously, I installed it to ~/anaconda3/lib/python3.4/site-packages)
1.1 I also added ~/anaconda3/lib/python3.4/site-packages/numpy/include to $PYTHONPATH and $PATH
2.  I ran these commands in Python:
   >>>import numpy 
   And I found it returns no error!
3.  I removed previously compiled files in directory build, and rebuilt. Finally it worked

希望这些对其他人有帮助。
