'main/accuracy and validation/main/loss' value is nothing and not printed during training.

Hi,

A validation data was prepared to validate training and validation, and an Evaluator was added. The code does not seem to be a problem compared to the example. 

However, no value is displayed in 'main / administrator' when executing 'PrintReport' regardless of adding validation. 

When adding and executing validation related code, an error occurs that the 'validation / main / loss, validation / main / verification' value is not displayed and the 'dtype' does not appear normal after the second epoch and the learning ends. 

Please understand the difficulty of sharing the entire code, and please give feedback to those who have similar experiences. 

Of course, there is no plot at all.  What causes it?

Nvidia Cuda 10.1

That's all.
