Restoring the Model

[leifsyliongka]

Hello, I'm trying out your code and I'm running the Test and Visualize attention results codes and I'm getting this the error below. Could it be that the sample model is already outdated? Thank you.

@leifsyliongka Same problem. Did you fix this error?

[leifsyliongka]

@BeSlower I was able to eventually run the code. The error is caused by the model being outdated with respect to the script. You'll have to train your own model.

same problem。when i train my own model,it works。
