我嘗試在P100節點上安裝和使用Theano與Cuda-9.0。安裝本身流暢，但我得到分段錯誤（見下文）。使用cuda-9.0的Theano段錯誤
我嘗試使用Theano-0.9.0和Theano-0.10.0beta1結合使用libgpuarray/pygpu - 0.6.8和0.6.9。所有的情況都會導致段錯誤。
這裏是我的設置： * 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.
