ValueError: GetLogdirSubdirectories: path exists and is not a directory

使用Tensorboard出现这个错误，说明你把--logdir的目录具体到了一个文件，所以删掉后面的文件就可以了，如果你是因为文件夹下有很多日志文件，想要具体到某一个日志文件，并且出现过错误：

TensorFlow installation not found - running with reduced feature set.
W1112 09:14:50.322900 139903131535104 plugin_event_accumulator.py:323] Found more than one graph event per run, or there was a metagraph containing a graph_def, as well as one or more graph events. Overwriting the graph with the newest event.

你只需要给原来的tensorboard --logdir='xxx' --port=xxxx多指定一个tensorboard --logdir='logs/' --event_file='logs/xxx文件'不过最好是把原来的日志信息删掉。
