笔精墨妙,妙手丹青,微软开源可视化版本的ChatGPT:Visual ChatGPT,人工智能AI聊天发图片,Python3.10实现
说时迟那时快，微软第一时间发布开源库Visual ChatGPT，把 ChatGPT 的人工智能AI能力和Stable Diffusion以及ControlNet进行了整合。常常被互联网人挂在嘴边的“赋能”一词，几乎已经变成了笑话，但这回，微软玩了一次真真正正的AI“赋能”，彻底打通了人工智能“闭环”。
配置Visual ChatGPT环境
老规矩，运行Git命令拉取Visual ChatGPT项目：
git clone https://github.com/microsoft/visual-chatgpt.git
进入项目目录：
cd visual-chatgpt
确保本机的Python版本不低于Python3.10.9
随后安装依赖文件：
pip3 install -r requirement.txt
这里有几个问题，一个是官方的Pytorch版本不是最新的，这里推荐1.13.1：
pip3 install torch==1.13.1
另外langchain的版本也推荐最新的107版本。
pip3 install langchain==0.0.107
安装好依赖之后，官方要求运行项目中的download.sh文件：
bash download.sh
这个shell脚本主要就是构建子项目ControlNet，同时下载所有的ControlNet模型，如果之前已经下载过相关模型，直接将模型文件拷贝到项目目录即可：
.
├── cldm_v15.yaml
├── cldm_v21.yaml
├── control_sd15_canny.pth
├── control_sd15_depth.pth
├── control_sd15_hed.pth
├── control_sd15_mlsd.pth
├── control_sd15_normal.pth
├── control_sd15_openpose.pth
├── control_sd15_scribble.pth
└── control_sd15_seg.pth
关于ControlNet，请移玉步至：登峰造极,师出造化,Pytorch人工智能AI图像增强框架ControlNet绘画实践,基于Python3.10， 这里不再赘述。
接着配置Openai的环境变量：
export OPENAI_API_KEY={你的openaik key}
如果是Windows用户，遵循下列步骤，配置好OPENAI_API_KEY：
打开“控制面板”，然后选择“系统和安全”。
选择“系统”，然后点击“高级系统设置”。
在“高级”选项卡下，点击“环境变量”。
在“用户变量”或“系统变量”下，选择要配置的变量，然后点击“编辑”。
在“变量值”字段中，输入要配置的值。
点击“确定”保存更改。
至此，大体上环境就配置好了。
Visual ChatGPT部分代码修改：
和ControlNet一样，Visual ChatGPT将运行方式写死为cuda，这对于不支持cuda模式的电脑不太友好，比如苹果M系列芯片的Mac系统，如果我们直接运行程序：
python3 visual_chatgpt.py
就会报这个错误：
AssertionError: Torch not compiled with CUDA enabled
这里需要将visual-chatgpt.py文件中写死的cuda模式改写为mps模式：
print("Initializing VisualChatGPT")
self.llm = OpenAI(temperature=0)
self.edit = ImageEditing(device="mps")
self.i2t = ImageCaptioning(device="mps")
self.t2i = T2I(device="mps")
关于MPS模式，请参照：闻其声而知雅意,M1 Mac基于PyTorch(mps/cpu/cuda)的人工智能AI本地语音识别库Whisper(Python3.10) ，这里不再赘述。
接着创建训练图片的文件夹：
mkdir image
随后还可能触发langchain库的内存溢出问题，需要将这行代码屏蔽：
# self.agent.memory.buffer = cut_dialogue_history(self.agent.memory.buffer, keep_last_n_words=500)
接着将内存缓冲区替换为保存上下文逻辑：
self.agent.memory.buffer = self.agent.memory.buffer + Human_prompt + 'AI: ' + AI_prompt
self.agent.memory.save_context({"input": Human_prompt}, {"output": AI_prompt})
当我们以为万事俱备只欠东风的时候，发现每次运行都会内存溢出，对此，官方给出了解释：
Here we list the GPU memory usage of each visual foundation model, one can modify self.tools with fewer visual foundation models to save your GPU memory:
Foundation Model Memory Usage (MB)
ImageEditing 6667
ImageCaption 1755
T2I 6677
canny2image 5540
line2image 6679
hed2image 6679
scribble2image 6679
pose2image 6681
BLIPVQA 2709
seg2image 5540
depth2image 6677
normal2image 3974
InstructPix2Pix 2795
这就是加载了所有模型之后的显存占用，整整70个G的显存占用，这是给人玩的吗？人们不禁要问。
没办法，只能另辟蹊径，将非必要的模型加载代码进行屏蔽操作，一顿修改，修改后的完整代码：

VISUAL_CHATGPT_PREFIX = """Visual ChatGPT is designed to be able to assist with a wide range of text and visual related tasks, from answering simple questions to providing in-depth explanations and discussions on a wide range of topics. Visual ChatGPT is able to generate human-like text based on the input it receives, allowing it to engage in natural-sounding conversations and provide responses that are coherent and relevant to the topic at hand.
Visual ChatGPT is able to process and understand large amounts of text and images. As a language model, Visual ChatGPT can not directly read images, but it has a list of tools to finish different visual tasks. Each image will have a file name formed as "image/xxx.png", and Visual ChatGPT can invoke different tools to indirectly understand pictures. When talking about images, Visual ChatGPT is very strict to the file name and will never fabricate nonexistent files. When using tools to generate new image files, Visual ChatGPT is also known that the image may not be the same as the user's demand, and will use other visual question answering tools or description tools to observe the real image. Visual ChatGPT is able to use tools in a sequence, and is loyal to the tool observation outputs rather than faking the image content and image file name. It will remember to provide the file name from the last tool observation, if a new image is generated.
Human may provide new figures to Visual ChatGPT with a description. The description helps Visual ChatGPT to understand this image, but Visual ChatGPT should use tools to finish following tasks, rather than directly imagine from the description.
Overall, Visual ChatGPT is a powerful visual dialogue assistant tool that can help with a wide range of tasks and provide valuable insights and information on a wide range of topics.
TOOLS:
------
Visual ChatGPT has access to the following tools:"""
VISUAL_CHATGPT_FORMAT_INSTRUCTIONS = """To use a tool, please use the following format:
Thought: Do I need to use a tool? Yes
Action: the action to take, should be one of [{tool_names}]
Action Input: the input to the action
Observation: the result of the action
When you have a response to say to the Human, or if you do not need to use a tool, you MUST use the format:
Thought: Do I need to use a tool? No
{ai_prefix}: [your response here]
"""
VISUAL_CHATGPT_SUFFIX = """You are very strict to the filename correctness and will never fake a file name if it does not exist.
You will remember to provide the image file name loyally if it's provided in the last tool observation.
Begin!
Previous conversation history:
{chat_history}
New input: {input}
Since Visual ChatGPT is a text language model, Visual ChatGPT must use tools to observe images rather than imagination.
The thoughts and observations are only visible for Visual ChatGPT, Visual ChatGPT should remember to repeat important information in the final response for Human.

编程的乐趣就在于，当你为了运行某个程序经历了千难万险，甚至濒临绝望的时候，突然，程序调通了，此时大脑皮层会大量分泌多巴胺（dopamine），那感觉，就像突然领悟了人生妙谛，又像是终于明白了天人化生、万物滋长的要道，简而言之，白日飞升，快乐加倍，那种精神上的享受，绝对比玩电子游戏或者享受美食更加的高级。
随后访问http://localhost:7860：
直接用中文开聊即可，不需要ControlNet那些令人厌烦的引导词。

Outputs: [('给我一只大金毛', 'Here is a golden retriever for you: *image/865c561f.png*')]
通过观察，我们可以得知，虽然是中文聊天，但其实ChatGPT会把中文翻译为英文，将“给我一只大金毛”翻译为：“a golden retriever”。
随后通过模型训练生成图片，再将聊天记录添加到上下文列表中，关于ChatGPT的聊天上下文，请参照：重新定义性价比!人工智能AI聊天ChatGPT新接口模型gpt-3.5-turbo闪电更新,成本降90%,Python3.10接入
当然，为了可以线下单机环境将Visual ChatGPT成功跑起来，所以屏蔽了多个ControlNet图像模型，因此有些图片场景并不那么尽如人意：
结语
有的时候，当我们称赞一项技术的时候，我们会称其为这样或者那样的行业标杆、教科书之类，但是对于ChatGPT来说，它已经超越了所谓的什么标杆，或者说得更准确一些，它是标杆中的标杆，其他的所谓的类ChatGPT产品，别说望其项背了，就连ChatGPT的尾气也闻不到，说白了，想碰瓷都不知道该怎么碰，因为神明早已在ChatGPT的命格中写下八个大字：前无古人，后无来者！最后，奉上修改后的项目代码，与众乡亲同飨：github.com/zcxey2911/visual_chatgpt_mps_cut
