筆精墨妙,妙手丹青,微軟開源視覺化版本的ChatGPT:Visual ChatGPT,人工智慧AI聊天發圖片,Python3.10實現
2023-03-13 12:00:52
說時遲那時快，微軟第一時間釋出開源庫Visual ChatGPT，把 ChatGPT 的人工智慧AI能力和Stable Diffusion以及ControlNet進行了整合。常常被網際網路人掛在嘴邊的「賦能」一詞，幾乎已經變成了笑話，但這回，微軟玩了一次真真正正的AI「賦能」，徹底打通了人工智慧「閉環」。
設定Visual ChatGPT環境
老規矩，執行Git命令拉取Visual ChatGPT專案：
git clone https://github.com/microsoft/visual-chatgpt.git
進入專案目錄：
cd visual-chatgpt
確保本機的Python版本不低於Python3.10.9
隨後安裝依賴檔案：
pip3 install -r requirement.txt
這裡有幾個問題，一個是官方的Pytorch版本不是最新的，這裡推薦1.13.1：
pip3 install torch==1.13.1
另外langchain的版本也推薦最新的107版本。
pip3 install langchain==0.0.107
安裝好依賴之後，官方要求執行專案中的download.sh檔案：
bash download.sh
這個shell指令碼主要就是構建子專案ControlNet，同時下載所有的ControlNet模型，如果之前已經下載過相關模型，直接將模型檔案拷貝到專案目錄即可：
.
├── 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
關於ControlNet，請移玉步至：登峰造極,師出造化,Pytorch人工智慧AI影象增強框架ControlNet繪畫實踐,基於Python3.10， 這裡不再贅述。
接著設定Openai的環境變數：
export OPENAI_API_KEY={你的openaik key}
如果是Windows使用者，遵循下列步驟，設定好OPENAI_API_KEY：
開啟「控制面板」，然後選擇「系統和安全」。
選擇「系統」，然後點選「高階系統設定」。
在「高階」索引標籤下，點選「環境變數」。
在「使用者變數」或「系統變數」下，選擇要設定的變數，然後點選「編輯」。
在「變數值」欄位中，輸入要設定的值。
點選「確定」儲存更改。
至此，大體上環境就設定好了。
Visual ChatGPT部分程式碼修改：
和ControlNet一樣，Visual ChatGPT將執行方式寫死為cuda，這對於不支援cuda模式的電腦不太友好，比如蘋果M系列晶片的Mac系統，如果我們直接執行程式：
python3 visual_chatgpt.py
就會報這個錯誤：
AssertionError: Torch not compiled with CUDA enabled
這裡需要將visual-chatgpt.py檔案中寫死的cuda模式改寫為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")
關於MPS模式，請參照：聞其聲而知雅意,M1 Mac基於PyTorch(mps/cpu/cuda)的人工智慧AI本地語音識別庫Whisper(Python3.10) ，這裡不再贅述。
接著建立訓練圖片的資料夾：
mkdir image
隨後還可能觸發langchain庫的記憶體溢位問題，需要將這行程式碼遮蔽：
# self.agent.memory.buffer = cut_dialogue_history(self.agent.memory.buffer, keep_last_n_words=500)
接著將記憶體緩衝區替換為儲存上下文邏輯：
self.agent.memory.buffer = self.agent.memory.buffer + Human_prompt + 'AI: ' + AI_prompt
self.agent.memory.save_context({"input": Human_prompt}, {"output": AI_prompt})
當我們以為萬事俱備只欠東風的時候，發現每次執行都會記憶體溢位，對此，官方給出瞭解釋：
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
這就是載入了所有模型之後的視訊記憶體佔用，整整70個G的視訊記憶體佔用，這是給人玩的嗎？人們不禁要問。
沒辦法，只能另闢蹊徑，將非必要的模型載入程式碼進行遮蔽操作，一頓修改，修改後的完整程式碼：

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: [('給我一隻大金毛', 'Here is a golden retriever for you: *image/865c561f.png*')]
通過觀察，我們可以得知，雖然是中文聊天，但其實ChatGPT會把中文翻譯為英文，將「給我一隻大金毛」翻譯為：「a golden retriever」。
隨後通過模型訓練生成圖片，再將聊天記錄新增到上下文列表中，關於ChatGPT的聊天上下文，請參照：重新定義價效比!人工智慧AI聊天ChatGPT新介面模型gpt-3.5-turbo閃電更新,成本降90%,Python3.10接入
當然，為了可以線下單機環境將Visual ChatGPT成功跑起來，所以遮蔽了多個ControlNet影象模型，因此有些圖片場景並不那麼盡如人意：
結語
有的時候，當我們稱讚一項技術的時候，我們會稱其為這樣或者那樣的行業標杆、教科書之類，但是對於ChatGPT來說，它已經超越了所謂的什麼標杆，或者說得更準確一些，它是標杆中的標杆，其他的所謂的類ChatGPT產品，別說望其項背了，就連ChatGPT的尾氣也聞不到，說白了，想碰瓷都不知道該怎麼碰，因為神明早已在ChatGPT的命格中寫下八個大字：前無古人，後無來者！最後，奉上修改後的專案程式碼，與眾鄉親同饗：github.com/zcxey2911/visual_chatgpt_mps_cut
