llmpart in the configuration is the meta-prompt llm.
This model must be a very strong model and should be some proprietary model (openAI/Anthropic/Google).
You can use a local model for the 'predictor' llm (depending on your task).Is it necessary to modify this configuration information to change meta-prompt llm? Can I download the google/flan-t5-xl model to my local computer and use it? But please check the error message above. I guess it may be a problem with the dataset. However, I don't have a dataset. Could you share an open source dataset for me to test?

num_workers: 5
prompt: 'prompts/predictor_completion/prediction.prompt'
mini_batch_size: 1
mode: 'annotation'- In order to modify the meta-prompt llm you need to change the llm that is outside the annotator/predictor. Simply use the GPT-2 only in the predictor part (all the rest LLMs should be strong models)
- Flan-T5 might be good as a predictor but not as the meta-prompt LLM
- You don't need a dataset The system supports zero-shot setting, and generates synthetic samples for the dataset. The issue you encounter is because the meta-prompt LLM that is responsible also for generating the dataset is not strong enough (therefore it doesn't generate the dataset)
If I want to run everything locally, where should I modify the meta-prompt LLM?
If you want to run everything locally then your modifications are correct.
However, as I said unless you have access to gpt-4 and run it locally, this simply not going to work. The meta-prompt task is too challenging for basic open-source models and you will not get a valid responseAlright, now I know where the problem lies. Although it cannot run entirely locally, I still really appreciate your response.
I'm using a local model, and I don't have a dataset. There's no data in my Argilla account as well. I can only generate some data myself based on the keywords in the code that are used to read datasets. Now there's an error, and I don't know where the problem lies.
Here is my error message：
