現象是只要運行model.fit或類似代碼來開始訓練定義好的模型, 服務就會掛掉, 需要重啟, 即使是最簡單的模型和數據
根據啟動jupyter的時候的命令行信息:
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/.
根據提示, 這樣可以修復
import os os.environ['KMP_DUPLICATE_LIB_OK']='True'
但是不推薦, 推薦的方式是
conda install nomkl
