错误描述

当我启用调试 per the docs 时，我无法访问任何调试信息。 get_event_time_info 抛出一个除以零的错误，而 get_llm_inputs_outputs 返回一个空列表。

版本

0.10.19

重现步骤

以下是我的脚本：

❯ cat ingest.py
import os

from llama_index.core import VectorStoreIndex, StorageContext, load_index_from_storage
from llama_index.core.storage.docstore import SimpleDocumentStore
from llama_index.core.vector_stores import SimpleVectorStore
from llama_index.readers.github import GithubRepositoryReader, GithubClient
from llama_index.core.callbacks import (
    CallbackManager,
    LlamaDebugHandler,
    CBEventType,
)

persistence_dir = "index"

github_token = os.getenv("GITHUB_TOKEN")
owner = "kubernetes"
repo = "kubernetes"
branch = "master"

llama_debug = LlamaDebugHandler(print_trace_on_end=True)
callback_manager = CallbackManager([llama_debug])

if os.getenv("RELOAD_INDEX") == "true":
    github_client = GithubClient(os.getenv("GITHUB_TOKEN"))

    print("getting docs")
    documents = GithubRepositoryReader(
        github_client,
        owner=owner,
        repo=repo,
        use_parser=False,
        verbose=False,
    ).load_data(branch=branch)

    print("creating vector store")
    index = VectorStoreIndex.from_documents(documents, callback_manager=callback_manager)

    print("persisting index")
    index.storage_context.persist(persist_dir=persistence_dir)
else:
    print("loading index")
    storage_context = StorageContext.from_defaults(persist_dir=persistence_dir)
    print("building index")
    index = load_index_from_storage(storage_context, callback_manager=callback_manager)

print("building engine")
query_engine = index.as_query_engine()

print("sending query")
response = query_engine.query(
    "what podcast fields does it parse?"
)
llama_debug.flush_event_logs()

print(response)

print("\n\n=======\nDEBUG\n=======\n\n")
print(llama_debug.get_event_time_info(CBEventType.LLM))

print()
event_pairs = llama_debug.get_llm_inputs_outputs()
print("event pairs", event_pairs)
print()
print(event_pairs[0][0])
print()
print(event_pairs[0][1].payload.keys())
print()
print(event_pairs[0][1].payload["response"])
print()

输出是

❯ python ingest.py

The podcast fields that are parsed include title, link, description, pubDate, guid, itunes:subtitle, itunes:summary, itunes:author, itunes:explicit, itunes:duration, itunes:keywords, itunes:image, media:content, and enclosure.
