内核似乎已经死亡。导入keras时它将自动重启

Question

 I tensorflow/core/platform/cpu_feature_guard.cc:141] 
Your CPU supports instructions that this TensorFlow binary was not compiled to use: SSE4.1 SSE4.2 AVX AVX2 FMA

Creating new thread pool with default inter op setting: 4. Tune using inter_op_parallelism_threads for best performance.
OMP: Error #15: Initializing libiomp5.dylib, but found libiomp5.dylib already initialized.
OMP: Hint: This means that multiple copies of the OpenMP runtime have been linked into the program. 
That is dangerous, since it can degrade performance or cause incorrect results.
The best thing to do is to ensure that only a single OpenMP runtime is linked into the process,
e.g. by avoiding static linking of the OpenMP runtime in any library. 
As an unsafe, unsupported, undocumented workaround you can set the environment variable 
KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, 
but that may cause crashes or silently produce incorrect results.

每当我尝试在木星NB上构建keras神经网络时。内核会自动死亡，并且它会在每个神经网络中发生。
