TensorFlow visual Tensorboard "No graph definition files were found." Error

Personally feel tensorflow relative to other in-depth learning Coulai said is relatively good installation, I began to install Theano had not been installed for several days, and finally have no way to install the TensorFlow, even a little problem is not out, one-time installation is good, Chong This I also optimistic tensorflow. TensorFlow support the Windows system, but the Python version to Python3 above, Python3 and Python2 still have quite a lot of difference, use the time to pay attention to. I use the win7,python3.5.2, compiler notepad++.

When visualized with Tensorboard, display "No graph definition files were found." Is the first question I've encountered. It turned out that the path was wrong.
The correct process is as follows: The generated log files are placed under the E:\tfCode\log_data folder

(1) Open the CMD Command window and place the path under E:\tfCode.

(2) Input Tensorboard--logdir=log_data, will automatically generate a Web site as shown below

(3) The Web site in Google Chrome browser open, it can be.

Note: The path to CMD is the path to the folder where the log resides, LogDir equals the folder where log is stored. Browsers suggest using Google Chrome.
Do not close the command window before opening the browser

Warning: must be in strict accordance with the above directory level to start cmd, run Ensorboard--logdir=log_data, or else an error (why so inflexible.) )--by Xuyiqiang
