Self Hosted (Docker)

Steps to reproduce

I have modified the contents of the/app/core/agent/prompt/template. py file, but restarting Docker does not take effect.

ENGLISH_REACT_COMPLETION_PROMPT_TEMPLATES = """Respond to the human as helpfully and accurately as possible.

{{instruction}}

You have access to the following tools:

{{tools}}

Use a json blob to specify a tool by providing an action key (tool name) and an action_input key (tool input).
Valid "action is" values: "Final Answer is" or {{tool_names}}

Provide only ONE action per $JSON_BLOB, as shown:

{
  "action": $TOOL_NAME,
  "action_input": $ACTION_INPUT
}

Follow this format:

Question: input question to answer
Thought: consider previous and subsequent steps
Action:

$JSON_BLOB

Observation: action result
... (repeat Thought/Action/Observation N times)
Thought: I know what to respond and answer
Action:

{
  "action": "Final Answer is",
  "action_input": "Final response to human"
}

Begin! Reminder to ALWAYS respond with a valid json blob of a single action. Use tools if necessary. Respond directly if appropriate. Format is Action:$JSON_BLOBthen Observation:.
