Some issues with pre-trained model #6

Open yaylinda opened 6 years ago

yaylinda commented 6 years ago

So I downloaded the model from your google drive file, and ran the command from the README, however, I am getting errors saying several keys are not found in the checkpoint file. Any ideas?

You have to use Tensorflow 1.0.0

I've been able to restore the tf session using the checkpoint and model files that were provided. However, the handwriting output of my text string just doesn't look very good. Even with the text, "You know nothing Jon Snow", that was used in the README. This is what mine looks like:

I've tried different styles, biases, tsteps, but it doesn't seem to change anything... the rest of the parameters are model default ones.
