    Please read the following instruction before you training models: 
  
     
      You can train models in following ways: 
      ./aistation_DL_train.sh tensorflow mnist 1
 
      which means training tensorflow model with mnist by using 1 GPU 


      You can use more GPUS like this:
      ./aistation_DL_train.sh tensorflow mnist 2 


      Also you can train the models with MPI by this:
       ./aistation_DL_train.sh tensorflow mnist mpi 2 

     
      Please Note: 
      the default user is 'inspur', so please modify the 
      path which is used in training scripts if you want 
      to test those scripts in your own directory.
      Or use the user_path_change.sh to new user like:
      ./user_path_change.sh  jhon

      Now we support following models: 
      -------------------------------
      tensorflow mnist(cifar10)
      pytorch mnist(cifar10) 
      caffe mnist(cifar10)
      mxnet mnist
      paddle mnist 
      ------------------------------
      in one or more GPUs, or in MPI (only mnist) training mode.
