说时迟那时快，微软第一工夫公布开源库 Visual ChatGPT，把 ChatGPT 的人工智能 AI 能力和 Stable Diffusion 以及 ControlNet 进行了整合。经常被互联网人挂在嘴边的“赋能”一词，简直曾经变成了笑话，但这回，微软玩了一次真真正正的 AI“赋能”，彻底买通了人工智能“闭环”。
配置 Visual ChatGPT 环境
老规矩，运行 Git 命令拉取 Visual ChatGPT 我的项目：
git clone https://github.com/microsoft/visual-chatgpt.git进入我的项目目录：
cd visual-chatgpt确保本机的 Python 版本不低于 Python3.10.9
随后装置依赖文件：
pip3 install -r requirement.txt这里有几个问题，一个是官网的 Pytorch 版本不是最新的，这里举荐 1.13.1：
pip3 install torch==1.13.1另外 langchain 的版本也举荐最新的 107 版本。
pip3 install langchain==0.0.107装置好依赖之后，官网要求运行我的项目中的 download.sh 文件：
bash download.sh这个 shell 脚本次要就是构建子项目 ControlNet，同时下载所有的 ControlNet 模型，如果之前曾经下载过相干模型，间接将模型文件拷贝到我的项目目录即可：
.
├── 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对于 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 绘画实际, 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：
关上“控制面板”，而后抉择“零碎和平安”。抉择“零碎”，而后点击“高级零碎设置”。在“高级”选项卡下，点击“环境变量”。在“用户变量”或“零碎变量”下，抉择要配置的变量，而后点击“编辑”。在“变量值”字段中，输出要配置的值。点击“确定”保留更改。至此，大体上环境就配置好了。
Visual ChatGPT 局部代码批改：
和 ControlNet 一样，Visual ChatGPT 将运行形式写死为 cuda，这对于不反对 cuda 模式的电脑不太敌对，比方苹果 M 系列芯片的 Mac 零碎，如果咱们间接运行程序：
python3 visual_chatgpt.py就会报这个谬误：
AssertionError: Torch not compiled with CUDA enabled这里须要将 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")对于 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 本地语音辨认库 Whisper(Python3.10)，这里不再赘述。
接着创立训练图片的文件夹：
mkdir image随后还可能触发 langchain 库的内存溢出问题，须要将这行代码屏蔽：
# 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留上下文逻辑：
self.agent.memory.buffer = self.agent.memory.buffer + Human_prompt + 'AI:' + AI_prompt
self.agent.memory.save_context({"input": Human_prompt}, {"output": AI_prompt})当咱们认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，官网给出了解释：
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

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。
没方法，只能另辟蹊径，将非必要的模型加载代码进行屏蔽操作，一顿批改，批改后的残缺代码：

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.

Outputs: [('给我一只大金毛', 'Here is a golden retriever for you: *image/865c561f.png*')]通过观察，咱们能够得悉，尽管是中文聊天，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，再将聊天记录增加到上下文列表中，对于 ChatGPT 的聊天上下文，请参照：从新定义性价比! 人工智能 AI 聊天 ChatGPT 新接口模型 gpt-3.5-turbo 闪电更新, 老本降 90%,Python3.10 接入
当然，为了能够线下单机环境将 Visual ChatGPT 胜利跑起来，所以屏蔽了多个 ControlNet 图像模型，因而有些图片场景并不那么尽如人意：
结语
有的时候，当咱们称誉一项技术的时候，咱们会称其为这样或者那样的行业标杆、教科书之类，然而对于 ChatGPT 来说，它曾经超过了所谓的什么标杆，或者说得更精确一些，它是标杆中的标杆，其余的所谓的类 ChatGPT 产品，别说望其项背了，就连 ChatGPT 的尾气也闻不到，说白了，想碰瓷都不晓得该怎么碰，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！最初，奉上批改后的我的项目代码，与众乡亲同飨：github.com/zcxey2911/visual\_chatgpt\_mps\_cut
