----------------------
The error message you're seeing is because
BasePromptTemplate is an abstract base class in the LlamaIndex library. This means it contains methods that are intended to be overridden in subclasses, and it cannot be instantiated directly. The methods
format,
format_messages,
get_template, and
partial_format are abstract methods in this class, which means you need to provide implementations for these methods in your subclass.
Here's a general structure of how you might create a subclass of
BasePromptTemplate:
from llama_index.prompts.base import BasePromptTemplate
class MyPromptTemplate(BasePromptTemplate):
def format(self, llm=None, **kwargs):
# Your implementation here
pass
def format_messages(self, llm=None, **kwargs):
# Your implementation here
pass
def get_template(self, llm=None):
# Your implementation here
pass
def partial_format(self, **kwargs):
# Your implementation here
passIn this example, replace the
# Your implementation here comments with the actual code for each method.
Please note that this is a hypothetical example and might not work as-is because the actual implementation of these methods is not provided in the extracts. For the exact usage, you should refer to the
LlamaIndex documentation ().
