啟動Tensorboard時發生錯誤：class BeholderHook(tf.estimator.SessionRunHook): AttributeError: module 'tensorflow.python.estimator.estimator_lib' has no attribute 'SessionRunHook'

報錯：class BeholderHook(tf.estimator.SessionRunHook):
AttributeError: module 'tensorflow.python.estimator.estimator_lib' has no attribute 'SessionRunHook'

檢查tensorboard的安裝情況：pip3 list

發現tensorboard與tensorflow的版本不一致；卸載 pip3 uninstall tensorboard；重新安裝

pip3 install tensorboard==1.6

發現tensorboard 不是系統命令，需要將tensorboard配置到環境變量中去，先查看安裝路徑：

pip3 show tensorboard

重新啟動：tensorboard --logdir=logs  成功啟動tensorboard
