我尝试在P100节点上安装和使用Theano与Cuda-9.0。安装本身流畅，但我得到分段错误（见下文）。使用cuda-9.0的Theano段错误
我尝试使用Theano-0.9.0和Theano-0.10.0beta1结合使用libgpuarray/pygpu - 0.6.8和0.6.9。所有的情况都会导致段错误。
这里是我的设置： * RHEL 7 * GCC：4.8.5 * CUDA 9.0 * cuDNN：5.1.5 *的Python：2.7.13 * cmake的：3.7.2

--------------------------------------------------------------------------
A process has executed an operation involving a call to the
"fork()" system call to create a child process. Open MPI is currently
operating in a condition that could result in memory corruption or
other system errors; your job may hang, crash, or produce silent
data corruption. The use of fork() (or system() or other calls that
create child processes) is strongly discouraged.
The process that invoked fork was:
Local host: [[52508,1],0] (PID 3946)
If you are *absolutely sure* that your application will successfully
and correctly survive a call to fork(), you may disable this warning
by setting the mpi_warn_on_fork MCA parameter to 0.
