我正在尝试安装 pyMPI ，以便将其与WARP程序包一起使用，以进行一些我可以在常规桌面上运行的低分辨率模拟。 WARP 的documentation表示我使用 pyMPI 的特定变体：
Warp传统上与pyMPI一起使用，但也适用于mpi4py。 （使用python3进行warp只适用于mpi4py。）pyMPI可以从NERSC的git获得。 （sourceforge版本不适用于Warp。）
git clone http://portal.nersc.gov/project/warp/git/pyMPI.git要构建，请运行以下命令，根据需要修改安装路径。
./configure --prefix=/place/to/install make install
但是，当我运行第一个命令时，配置失败，输出如下：

我打算在Python 2.7中使用WARP，这是默认设置。
[krishnadev@localhost ~] $ python --version
Python 2.7.13
但似乎配置脚本似乎检测到Python 3：
checking for Python... /usr/bin/python3.5m-x86_64-config
错误输出的最后一行也是
configure: error: Your python distribution is incomplete. Perhaps there is no XXX/lib/python2.x/config
但存在以下文件夹：
[krishnadev@localhost ~] $ ls /usr/lib64/python2.7/config/
config config.c.in libpython2.7.so makesetup Setup Setup.local
config.c install-sh Makefile python.o Setup.config
，而
[krishnadev@localhost ~] $ ls /usr/lib64/python3.*/config/
ls: cannot access '/usr/lib64/python3.*/config/': No such file or directory
[krishnadev@localhost ~] $ ls /usr/lib/python*/config/
ls: cannot access '/usr/lib/python*/config/': No such file or directory
我正在运行Fedora 25 Scientific（64位），我还没有在其他系统上测试过。谁能帮助我如何建立pyMPI？
我强迫它使用Python 2.7和
./configure --with-python=/usr/bin/python2.7
现在配置完成了，但有一些警告：

但是，我仍然无法成功构建和安装 - 最后我收到以下错误：
/usr/bin/ld: libpyMPI.a(pyMPI_main.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
libpyMPI.a: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
Makefile:506: recipe for target 'pyMPI' failed
make: *** [pyMPI] Error 1
问题应该是什么以及如何解决？
另外，我应该如何使用 mpi4py 而不是 pyMPI ？文档说它是可能的：
Warp传统上与pyMPI一起使用，但也适用于mpi4py。
我通常会使用以下命令进行模拟：
mpirun -np 4 pyMPI warp_script.py
我使用 pip 安装 mpi4py ，但有人可以指导我使用它来代替 pyMPI 吗？
答案 0 :(得分：0)
通过在配置时传递以下参数来解决问题：
./configure --with-python=/usr/bin/python2.7 CFLAGS="-fPIC"
这特别强制使用Python 2.7，并且在构建时传递CFLAGS也消除了错误。
