I have met the same issue with you.The test loss is high. Did you solve the issue?
How long we need to iterate? I have gone for more than 14000 iterations in 10 hours. Is not enough?
enough is when you satisfied with output. sometimes something is wrong and training not going well at all and ya can train forewer without successes.
you need to play with your data and settings. chose smaller params first then move to bigger ones to see do it works at all
I trained it for 73000 iterations but still i am getting same results like ? and .
this is settings in my config.py last iteration is 62800

i even have the same setting in config.py as your and my last iteration was 117000, but still only exclaimations and dots!!! @MartinAbilev
something is wrong looks like with code or training data. it is hard to tell what exactly. you can create repo with your code and drop link.
Ok. I'm gonna check MartinAbilev's code out and see if it works and see what is the difference. I'll update if I find any.
Unfortunately I have the same blank results. Something isn't working right with the code out of the box. Adjusting parameters made it worse.
If you're not wed to using this particular model, this one works better than any other I've seen out in the open: https://github.com/pender/chatbot-rnn
It can be insulting though, as it was trained on reddit data, so be forewarned.
Train your model and check. You can train with your custom small dataset line-by-line dialog:
=== Hi Hello, How are you? I am fine. Thanks. What are you doing? I am just chatting with you.
I think the model is too simple! So its matching competence is not enough to hold so much data. When I use 189999 samples, the final loss is around 2.2. When 110000 samples, corresponding loss is around 2.0. When lower samples, loss is still decreasing! Hope this can help you.
