codellama issue in bigdl-llm

[jiafuzha]

In bigdl-llm 2.4, transformers version is 4.31. But codellama example needs 4.34.1.
In bigdl-llm 2.5.0b20240130, transformers version is still 4.31. @gc-fu told me bigdl-llm 2.5.0b20240130 is compatible with transformers 4.36. As tested, codellama works well with transformers 4.35.0, but not 4.36. In 4.36, the generated just repeats the prompt.

1. case 1

Prompt: "Once upon a time, "
Output: "Once upon a time, Once upon a time, Once upon a time, Once upon a time, Once upon a time, Once upon a time, Once upon a time, Once upon a time, Once upon a time, Once upon a time, Once upon a time, Once upon a time, Once upon a time, Once upon a time"

2. case 2
   Prompt: "What is AI?"
   Output: "What is AI? What is AI? What is AI? What is AI? What is AI? What is AI? What is AI? What is AI? What is AI? What is AI? What is AI? What is AI? What is AI? What is AI?"

Hi, I am working on this and will try to reproduce the issue first.

May I ask what environment are you using? Can you list the output of lscpu or are you using XPU?

It's SPR node. no XPU.

The transformer version 4.34.1 works normally for codellama as mentioned in our examples.

For transformer version 4.36, @jenniew can you have a look on this and fix this issue, thanks 😃

Updates will be listed in this issue once we fix the issue.

On SPR I tested bigdl llm with codellama-7b-hf model on transformers 4.36.2.
-------------------- Prompt --------------------
Once upon a time
<FILL_ME>
-------------------- Output --------------------
Once upon a time

Once upon a time, there was a king who had a daughter. She was very beautiful, and she was very smart. She was very good at math

-------------------- Prompt --------------------
What is AI
<FILL_ME>
-------------------- Output --------------------
What is AI

Artificial intelligence (AI) is the ability of a computer to learn and make decisions without being explicitly programmed.

AI is a field

The result seems OK. Can you try latest version of bigdl-llm and check if tokenizer/prompt is OK?
