《生成式 AI》课程 第3講：訓練不了人工智慧嗎？你可以訓練你自己-CSDN博客
我们希望你设计一个机器人服务，你可以用LM玩角色扮演游戏。
与LM进行多轮对话
提示:告诉聊天机器人扮演任意角色。
后续输入:与聊天机器人交互。
Part 2: Role-Play
In this task, you are asked to prompt your chatbot into playing a roleplaying game. You should assign it a character, then prompt it into that character.
You need to:
- Come up with a character you want the chatbot to act and the prompt to make the chatbot into that character. Fill the character in character_for_chatbot, and fill the prompt in prompt_for_roleplay.
- Hit the run button
. (The run button will turn into this state
when sucessfully executed.) It will pop up an interface that looks like this: (It May look a little bit different if you use dark mode.) 
- Interact with the chatbot for 2 rounds. Type what you want to say in the block "Input", then hit the button "Send". (You can use the "Temperature" slide to control the creativeness of the output.)
- If you want to change your prompt or the character, hit the run button again to stop the cell. Then go back to step 1.
- After you get the desired result, hit the button "Export" to save your result. There will be a file named part2.json appears in the file list. Remember to download it to your own computer before it disappears.
Note:
- If you hit the "Export" button again, the previous result will be covered, so make sure to download it first.
- You should keep in mind that even with the exact same prompt, the output might still
- differ.
以下的代码需要魔法，并且有OpenAI的账号才能使用
