mpi_train.sh包含以下行：
mpiexec.hydra -prepend-rank -host node11 -n 16
在并行caffe中运行examples / cifar10 / mpi_train_quick.sh时出现以下错误：
F0521 18:33:32.101737 16179 caffe.cpp:293] This MPI version is NOT support multi-thread!

我已经安装了mpich-3.1.4版本。 当我做哪个mpirun，哪个mpiexec，哪个mpicc，我从所有这些到达mpich-3.1.4文件夹的路径 此外，系统同时安装了Open-Mpi和MPICH-3.1.4，因为在安装opencv时会自动安装open-mpi，这是并行caffe的先决条件。我该如何解决这个错误？
