现象是只要运行model.fit或类似代码来开始训练定义好的模型, 服务就会挂掉, 需要重启, 即使是最简单的模型和数据
根据启动jupyter的时候的命令行信息:
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. For more information, please see http://www.intel.com/software/products/support/.
根据提示, 这样可以修复
import os os.environ['KMP_DUPLICATE_LIB_OK']='True'
但是不推荐, 推荐的方式是
conda install nomkl
