THEN Modify the prompt template to enforce that every 'Thought:' is immediately followed by either an 'Action:' plus 'Action Input:' or a 'Final Answer:'. This can be done by appending an instruction like 'IMPORTANT: After each Thought you MUST output exactly one Action/Action Input or Final Answer. Do not include any other text.' to the system or user prompt. Alternatively, reinstall the correct version of LangChain to ensure the feature works as expected.

from langchain.prompts import PromptTemplate
original_prompt = agent.agent.llm_chain.prompt.template
new_prompt = original_prompt + "\n\nIMPORTANT: After each Thought you MUST output exactly one Action/Action Input or Final Answer. Do not include any other text."
agent.agent.llm_chain.prompt = PromptTemplate(template=new_prompt, input_variables=agent.agent.llm_chain.prompt.input_variables)
