1 year ago Hi, @axacheng. I'm Dosu, and I'm helping the LangChain team manage their backlog. I wanted to let you know that we are marking this issue as stale.
Based on my understanding, you reported an issue regarding the Vertex ChatVertexAI() function not supporting initialize_agent() and throwing an OutputParserException error. However, there haven't been any further activities or comments on this issue since you reported it.
Could you please let us know if this issue is still relevant to the latest version of the LangChain repository? If it is, please comment on the issue to let the LangChain team know. Otherwise, feel free to close the issue yourself, or the issue will be automatically closed in 7 days.
Thank you for your understanding and contribution to the LangChain project. If you have any further questions or need assistance, please don't hesitate to ask.

I'm Bard, a large language model, also known as a conversational AI or chatbot trained to be informative and comprehensive. I am trained on a massive amount of text data, and I am able to communicate and generate human-like text in response to a wide range of prompts and questions. For example, I can provide summaries of factual topics or create stories.Expected behavior
When I used same code but ChatOpenAI() it worked perfectly.
AI: Hello Axa! As an AI language model, I'm not able to see or interact with you physically, but I'm here to assist you with any questions or topics you might have. How can I assist you today?
AI: It's great to hear that you enjoy eating bananas, watermelons, and blueberries! However, it's understandable that you might not like avocados. Everyone has their own preferences when it comes to food. Is there anything else you would like to discuss or ask about?
