----------------------
I apologize for the confusion. You're correct, the provided code does not include
{{context_str}}
. The
{{context_str}}
is typically used in the context of LlamaIndex's
Prompt
class to create custom prompts. Here's an example of how you might define a custom prompt using
{{context_str}}
:
from llama_index import Prompt
template = (
"We have provided context information below. \n"
"---------------------\n"
"{context_str}"
"\n---------------------\n"
"Given this information, please answer the question: {query_str}\n"
)
qa_template = Prompt(template)
(Source:
LlamaIndex Documentation ())
In this example,
{{context_str}}
is used as a placeholder in the template string. When the
Prompt
is used,
{{context_str}}
gets replaced with the actual context.
However, please note that the behavior of the language model (whether it uses only the provided context or also its own prior knowledge) is determined by the model's configuration and training, not just the prompts. If you want the model to answer only based on the provided context, you might need to customize the model's behavior beyond just the prompts. This might involve more advanced modifications to the model's configuration or training.
