keras啓用tensorboard

在callback函數中添加tensorboard，啓用tensorboard。

# TensorBoard callback
tensorboard_cb = K.callbacks.TensorBoard(
    log_dir=MyTensorBoardDir,
    histogram_freq=1,
    write_graph=True,
    write_images=True
)

在fit數據的時候，把該回調添加進去

model.fit(x,y,epochs=Epoch,batch_size=16,verbose=2,validation_split=0.2,callbacks=callbackList)
