@sde123 The mpi version is too old. To install a newer version, please download the source from here, then tar xf openmpi-1.10.7.tar.gz
cd openmpi-1.10.7
./configure --with-cuda=/usr/local/cuda --enable-mpi-thread-multiple
make -j8
sudo make install
cd -This will by default install it to export PATH=/usr/local/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATHRestart the terminal, |

@sde123 This means the training failed. Have you compiled the caffe successfully with the new openmpi? |

@sde123 Yeah, I know the Makefile.config. I mean are there any errors when you run A tip: when copy and paste something, please use the following syntax to wrap the content, for example, ``` This will make it much more readable. |

Could you please check the outputs of the following commands ldd external/caffe/build/tools/caffe | grep mpi
which mpi
mpirun --version
echo $LD_LIBRARY_PATH |
|
Thank you,I check the commands and got the following information dai@dai-System-Product-Name:~/code/person_reidentification/3/dgd_person_reid$ which mpi dai@dai-System-Product-Name:~/code/person_reidentification/3/dgd_person_reid$ mpirun --version Report bugs to http://www.open-mpi.org/community/help/ |

@Cysu |

@sde123 Sorry for my typo, it should be ldd external/caffe/build/tools/caffe | grep mpiPlease use ``` (the tilde character left to number 1 on keyboard) instead of ... when paste the content. Thanks. |
|
@Cysu I donnot know what is wrong in my case. the following is my mpi: Thank you |
|
@sde123 The command should be ldd external/caffe/build/tools/caffe | grep mpiNote that it is By the way, what's your GPU memory size? |
|
@Cysu So ,I make the caffe again,I got a measage when run make runtest -j8 in external/caffe: Did it mean that my external/caffe is wrong? |
|
@Cysu |
|
Could you please first check that the following commands report the same library paths? ldd $(which mpirun) | grep mpi
ldd external/caffe/build/tools/caffe | grep mpi |
|
@Cysu why I got no report with inputting "ldd $(which mpirun) | grep mpi" to the terminal. I have install mpi ,and I can find it in the usr/local/lib and usr/local/include. |
|
Sorry, my fault. It should be ldd $(which mpirun) | grep open-
ldd external/caffe/build/tools/caffe | grep open- |
|
@Cysu and I got the report: I input the and got the report: the two report are almost same |
|
Yes, that means the mpi are configured correctly. Could you please show the output of |
@Cysu
Thankyou very much for your code on person re_identification
I have install openmpi-1.6.5
But when I make -j8 in the external/caffe,I got a error:

The following is my Makefile.config:
Refer to http://caffe.berkeleyvision.org/installation.html
Contributions simplifying and improving our build system are welcome!
cuDNN acceleration switch (uncomment to build with cuDNN).
USE_CUDNN := 1
MPI data parallelization switch (uncomment to build with MPI).
USE_MPI := 1
MPI_INCLUDE := /usr/local/include
MPI_LIB := /usr/local/lib
CPU-only switch (uncomment to build without GPU support).
CPU_ONLY := 1
To customize your choice of compiler, uncomment and set the following.
N.B. the default for Linux is g++ and the default for OSX is clang++
CUSTOM_CXX := g++
CUDA directory contains bin/ and lib/ directories that we need.
CUDA_DIR := /usr/local/cuda
On Ubuntu 14.04, if cuda tools are installed via
"sudo apt-get install nvidia-cuda-toolkit" then use this instead:
CUDA_DIR := /usr
CUDA architecture setting: going with all of them.
For CUDA < 6.0, comment the *_50 lines for compatibility.
CUDA_ARCH := -gencode arch=compute_20,code=sm_20
-gencode arch=compute_20,code=sm_21
-gencode arch=compute_30,code=sm_30
-gencode arch=compute_35,code=sm_35
-gencode arch=compute_50,code=sm_50
-gencode arch=compute_50,code=compute_50
BLAS choice:
atlas for ATLAS (default)
mkl for MKL
open for OpenBlas
BLAS := atlas
Custom (MKL/ATLAS/OpenBLAS) include and lib directories.
Leave commented to accept the defaults for your choice of BLAS
(which should work)!
BLAS_INCLUDE := /path/to/your/blas
BLAS_LIB := /path/to/your/blas
Homebrew puts openblas in a directory that is not on the standard search path
BLAS_INCLUDE := $(shell brew --prefix openblas)/include
BLAS_LIB := $(shell brew --prefix openblas)/lib
This is required only if you will compile the matlab interface.
MATLAB directory should contain the mex binary in /bin.
MATLAB_DIR := /usr/local/MATLAB/R2014a
MATLAB_DIR := /Applications/MATLAB_R2012b.app
NOTE: this is required only if you will compile the python interface.
We need to be able to find Python.h and numpy/arrayobject.h.
PYTHON_INCLUDE := /usr/include/python2.7
/usr/lib/python2.7/dist-packages/numpy/core/include
Anaconda Python distribution is quite popular. Include path:
Verify anaconda location, sometimes it's in root.
ANACONDA_HOME := $(HOME)/anaconda
PYTHON_INCLUDE := $(ANACONDA_HOME)/include \
We need to be able to find libpythonX.X.so or .dylib.
PYTHON_LIB := /usr/local/lib
PYTHON_LIB := $(ANACONDA_HOME)/lib
Homebrew installs numpy in a non standard path (keg only)
PYTHON_INCLUDE +=$(dir $ (shell python -c 'import numpy.core; print(numpy.core.file)'))/include
PYTHON_LIB += $(shell brew --prefix numpy)/lib
Uncomment to support layers written in Python (will link against Python libs)
WITH_PYTHON_LAYER := 1
Whatever else you find you need goes here.
INCLUDE_DIRS := $(PYTHON_INCLUDE) /usr/local/include
LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib
If Homebrew is installed at a non standard location (for example your home directory) and you use it for general dependencies
INCLUDE_DIRS += $(shell brew --prefix)/include
LIBRARY_DIRS += $(shell brew --prefix)/lib
Uncomment to use
pkg-configto specify OpenCV library paths.(Usually not necessary -- OpenCV libraries are normally installed in one of the above $LIBRARY_DIRS.)
USE_PKG_CONFIG := 1
BUILD_DIR := build
DISTRIBUTE_DIR := distribute
Uncomment for debugging. Does not work on OSX due to BVLC/caffe#171
DEBUG := 1
The ID of the GPU that 'make runtest' will use to run unit tests.
TEST_GPUID := 0
enable pretty build (comment to see full commands)
Q ?= @
Could you please tell me how to solve it?
Thank you very much!
