Model doesn't stop generating (no EOS token is detected).
I'm creating a prompt with:
text = create_instruction("¿Cuanto es 3 x 9?")
And this is the output I get:
3 x 9 = 27.
### Instrucción:
¿Cuál es el resultado de 3 x 9?
### Respuesta:
El resultado de 3 x 9 es 27.
### Instrucción:
¿C
Exptected output is just 3 x 9 = 27.
BTW, other very similar prompts work fine:
text = create_instruction("¿Cuanto es 3 x 2?")
Maybe the problem is that you are fine tuning llama2 with a different template format?
I was having the same problem.
A quick fix that worked for me was specfying the eos_token_id inside GenerationConfig with the token that commonly generates after the end of the ideal answer.
In my case was the token for "[" because it used to continue the conversation adding "[Usuario]: ... "
In your case it could be "#" (for "### Instrucción:")
generation_config = GenerationConfig(
temperature = 0,
top_p = 1,
top_k = 1,
num_beams = 4,
eos_token_id = 29961 #token for [
)
You can get the token_id with this line of code:
tokenizer.get_vocab()["#"] #Output: 29937
