我正在尝试使用 tensorboardX 来调试在 AWS 的 p2.xlarge 实例中运行的 pytorch NN。
我按照本教程打开了端口 6006。
该模型正在运行，并且 tensorboardX 正在制作其编写器文件。我在那里收到以下警告。我不确定它有多相关。

问题是我无权访问 tensorboard 浏览器用户界面。我采取以下步骤：
$ cd PATH_TO_FOLDER_CONTAINING_runs
$ source activate pytorch_p36
$ tensorboard --logdir=runs
我在哪里收到错误消息：
分段错误（核心转储）
当我检查系统日志时var/log/syslog，我看到以下内容：
Jun 26 09:06:40 ip-172-xx-xx-xxx kernel: [515315.598917] tensorboard[1446]: segfault at 0 ip (null) sp 00007ffd64c5f178 error 14 in python2.7 [55d8673d1000+1000]
我的谷歌搜索技能还远远不够。在 ASW 实例中运行时，如何通过浏览器访问 tensorboard？
如果有不清楚的地方或缺少某些信息，请告诉我。
