All this is implemented with a starter code for you to take it and use it in your Llama 2 projects."]},{"cell_type":"markdown","source":["##**0 - Prerequisites**\n","* Basic understanding of Large Language Models\n","\n","* Basic understanding of Python"],"metadata":{"id":"ioVMNcTesSEk"}},{"cell_type":"code","execution_count":2,"metadata":{"id":"ktEA7qXmwdUM","executionInfo":{"status":"ok","timestamp":1695832228254,"user_tz":420,"elapsed":248,"user":{"displayName":"Amit Sangani","userId":"11552178012079240149"}}},"outputs":[],"source":["# presentation layer code\n","\n","import base64\n","from IPython.display import Image, display\n","import matplotlib.pyplot as plt\n","\n","def mm(graph):\n","  graphbytes = graph.encode(\"ascii\")\n","  base64_bytes = base64.b64encode(graphbytes)\n","  base64_string = base64_bytes.decode(\"ascii\")\n","  display(Image(url=\"https://mermaid.ink/img/\" + base64_string))\n","\n","def genai_app_arch():\n","  mm(\"\"\"\n","  flowchart TD\n","    A[Users] --> B(Applications e.g. mobile, web)\n","    B --> |Hosted API|C(Platforms e.g. Custom, HuggingFace, Replicate)\n","    B -- optional --> E(Frameworks e.g. LangChain)\n","    C-->|User Input|D[Llama 2]\n","    D-->|Model Output|C\n","    E --> C\n","    classDef default fill:#CCE6FF,stroke:#84BCF5,textColor:#1C2B33,fontFamily:trebuchet ms;\n","  \"\"\")\n","\n","def rag_arch():\n","  mm(\"\"\"\n","  flowchart TD\n","    A[User Prompts] --> B(Frameworks e.g. LangChain)\n","    B <--> |Database, Docs, XLS|C[fa:fa-database External Data]\n","    B -->|API|D[Llama 2]\n","    classDef default fill:#CCE6FF,stroke:#84BCF5,textColor:#1C2B33,fontFamily:trebuchet ms;\n","  \"\"\")\n","\n","def llama2_family():\n","  mm(\"\"\"\n","  graph LR;\n","      llama-2 --> llama-2-7b\n","      llama-2 --> llama-2-13b\n","      llama-2 --> llama-2-70b\n","      llama-2-7b --> llama-2-7b-chat\n","      llama-2-13b --> llama-2-13b-chat\n","      llama-2-70b --> llama-2-70b-chat\n","      classDef default fill:#CCE6FF,stroke:#84BCF5,textColor:#1C2B33,fontFamily:trebuchet ms;\n","  \"\"\")\n","\n","def apps_and_llms():\n","  mm(\"\"\"\n","  graph LR;\n","    users --> apps\n","    apps --> frameworks\n","    frameworks --> platforms\n","    platforms --> Llama 2\n","    classDef default fill:#CCE6FF,stroke:#84BCF5,textColor:#1C2B33,fontFamily:trebuchet ms;\n","  \"\"\")\n","\n","import ipywidgets as widgets\n","from IPython.display import display, Markdown\n","\n","# Create a text widget\n","API_KEY = widgets.Password(\n","    value='',\n","    placeholder='',\n","    description='API_KEY:',\n","    disabled=False\n",")\n","\n","def md(t):\n","  display(Markdown(t))\n","\n","def bot_arch():\n","  mm(\"\"\"\n","  graph LR;\n","  user --> prompt\n","  prompt --> i_safety\n","  i_safety --> context\n","  context --> Llama_2\n","  Llama_2 --> output\n","  output --> o_safety\n","  i_safety --> memory\n","  o_safety --> memory\n","  memory --> context\n","  o_safety --> user\n","  classDef default fill:#CCE6FF,stroke:#84BCF5,textColor:#1C2B33,fontFamily:trebuchet ms;\n","  \"\"\")\n","\n","def fine_tuned_arch():\n","  mm(\"\"\"\n","  graph LR;\n","      Custom_Dataset --> Pre-trained_Llama\n","      Pre-trained_Llama --> Fine-tuned_Llama\n","      Fine-tuned_Llama --> RLHF\n","      RLHF --> |Loss:Cross-Entropy|Fine-tuned_Llama\n","      classDef default fill:#CCE6FF,stroke:#84BCF5,textColor:#1C2B33,fontFamily:trebuchet ms;\n","  \"\"\")\n","\n","def load_data_faiss_arch():\n","  mm(\"\"\"\n","  graph LR;\n","      documents --> textsplitter\n","      textsplitter --> embeddings\n","      embeddings --> vectorstore\n","      classDef default fill:#CCE6FF,stroke:#84BCF5,textColor:#1C2B33,fontFamily:trebuchet ms;\n","  \"\"\")\n","\n","def mem_context():\n","  mm(\"\"\"\n","      graph LR\n","      context(text)\n","      user_prompt --> context\n","      instruction --> context\n","      examples --> context\n","      memory --> context\n","      context --> tokenizer\n","      tokenizer --> embeddings\n","      embeddings --> LLM\n","      classDef default fill:#CCE6FF,stroke:#84BCF5,textColor:#1C2B33,fontFamily:trebuchet ms;\n","  \"\"\")\n"]},{"cell_type":"markdown","source":["##**1 -
