Please stand by @andysingal as I search the knowledge base. I normally take about 20 seconds or so. :wave:

----------------------
Based on the knowledge sources provided, the correct way to import ChatMessage and MessageRole is as follows:

Plain Text

from llama_index.core.llms import ChatMessage, MessageRole

However, there is no mention of BaseChatEngine in the provided knowledge sources. Therefore, I cannot confirm if the import statement for BaseChatEngine is correct. Please refer to the official LlamaIndex documentation or source code for more information.

Let me check the knowledge base for you. One moment! :books:

kkapa.ai

----------------------
The error message you're seeing is indicating that the LlamaParse object requires an API key to be instantiated. You can obtain this API key from <https://cloud.llamaindex.ai.>

Here's how you can instantiate LlamaParse with an API key:

Plain Text

from llama_parse import LlamaParse

parser = LlamaParse(
    api_key="llx-...",  # replace with your actual API key
    verbose=True,
)

Please replace "llx-..." with your actual API key. You can also set the API key in your environment variables as LLAMA_CLOUD_API_KEY.

For more information, please refer to the LlamaParse documentation ().
