自从升级到 TF 1.4 后，当我尝试运行时出现此错误tensorboard:
Traceback (most recent call last):
File "/opt/python/3.6.3/bin/tensorboard", line 11, in <module>
sys.exit(main())
File "/opt/python/3.6.3/lib/python3.6/site-packages/tensorboard/main.py", line 39, in main
return program.main(default.get_plugins(),
File "/opt/python/3.6.3/lib/python3.6/site-packages/tensorboard/default.py", line 71, in get_plugins
debugger = debugger_plugin_loader.get_debugger_plugin()
File "/opt/python/3.6.3/lib/python3.6/site-packages/tensorboard/plugins/debugger/debugger_plugin_loader.py", line 46, in get_debugger_plugin
if FLAGS.debugger_data_server_grpc_port is None:
File "/opt/python/3.6.3/lib/python3.6/site-packages/absl/flags/_flagvalues.py", line 509, in __getattr__
raise _exceptions.UnparsedFlagAccessError(error_message)
absl.flags._exceptions.UnparsedFlagAccessError: Trying to access flag --debugger_data_server_grpc_port before flags were parsed.
即使只是输入，我也会收到此错误tensorboard没有--logdir指定，而且当我指定日志目录时。我注意到 5 天前已经在 github 上报告了这一点（https://github.com/tensorflow/nmt/issues/176 https://github.com/tensorflow/nmt/issues/176），但我很惊讶没有看到更多人报告这一点。
我还注意到上周出于同样的原因我无法运行 Tensorflow RNN 教程，该错误还表明标记在解析之前已被访问。有人遇到过这个问题吗？你能告诉我是否有解决办法吗？
按照本说明中的指示Github问题 https://github.com/tensorflow/tensorboard/issues/764，快速修复是将 Tensorboard 升级到夜间构建：
pip install --upgrade tb-nightly
正如还解释的那样，一旦 TensorFlow nightly 20171122 发布，这个问题就会得到解决。
