tensorflow visualization tensorboard “No graph definition files were found.” error

In the use of tensorboard When visualizing tools , The phenomenon that newcomers will encounter is that there is no picture to show . I also encountered such a situation , Here is a summary

One 、 routing problem ：tensorboard --logdir=logs
It is located in logs Of documents Previous level directory , And then in cmd Enter the above statement in

Two 、 Space question ： See if you can type more and less blanks
（1） Fill in more blanks ：
It could be Python The habitual cause of , Be careful ！！！
Not in logdir and logs Put a space in the middle

 Correct format ：tensorboard --logdir=logs 
 Error model ：tensorboard --logdir = logs ( error ！！！） 

（2） Less space ：
Is in the tensorboard and logdir A space is missing between

 Correct format ：tensorboard --logdir=logs 
 Error model ：tensorboard--logdir=logs ( error ！！！）
