Jupyter notebook中的問題

 

 

• 問題錄

1.  （Ubuntu18.04）在運行程序時，在啓動jupyter的Terminal中，出現  “Your CPU supports instructions that this TensorFlow binary was not compiled to use : AVX2 FMA”
   1. 解決方案：    在程序中添加兩行代碼

      import os
      os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'    # 忽略哪些報告

2. Ubuntu18.04）在運行程序時，在啓動jupyter的Terminal中，出現如下報錯：

   Your CPU supports instructions that this TensorFlow binary was not compiled to use: AVX2 FMA
   Successfully opened dynamic library libcuda.so.1
   unable to create StreamExecutor for CUDA:0: failed initializing StreamExecutor for CUDA device ordinal 0: Internal: failed call to cuDevicePrimaryCtxRetain: CUDA_ERROR_OUT_OF_MEMORY: out of memory; total memory reported: 8366784512

   KernelRestarter: restarting kernel (1/5), keep random ports

   The kernel appears to have died. It will restart automatically.

    
   1.  原因分析：顯卡內存不足，因爲在使用TensorFlow做人工神經網絡運算時，會默認佔用GPU所有的顯存，這樣以防止被其他程序佔用。
   2.  問題解決：
      1. 重啓 jupyter note book，清除已佔用的GPU內存。
      2. 或者：在程序中加入(待驗證）

         import os
         os.environ['KMP_DUPLICATE_LIB_OK'] = 'TRUE'
