📁 Understanding File Types and Formats

AI Model File Formats Explained

.gguf (GGML Unified Format)

Modern format for running AI locally. Works with Ollama, LM Studio.

Example: llama-2-7b-chat.Q4_K_M.gguf

.safetensors

Safe, efficient format. Prevents code execution exploits.

Example: model.safetensors

.bin (Binary)

Older PyTorch format. Still widely used.

Example: pytorch_model.bin

.pth (PyTorch)

Another PyTorch format for model weights.

Example: model_checkpoint.pth

Common AI File Types You'll See

.txt

Plain text (simplest format)

.json

Data format for AI configs

.csv

Spreadsheet data for training

.md

Markdown for documentation

.py

Python code files

.ipynb

Jupyter notebooks (AI tutorials)

Where AI Stores Files

Windows:

C:\Users\[YourName]\.cache\huggingface\ = Downloaded models

C:\Users\[YourName]\AppData\Local\LM Studio\ = LM Studio files

Mac:

~/.cache/huggingface/ = Downloaded models

~/Library/Application Support/LM Studio/ = LM Studio files

⚠️
SIZE WARNING:

Models are 4-40GB each! Check disk space.

💻 Command Line Basics (Only Essentials)

Windows Command Prompt

How to open:
  1. Press Windows key
  2. Type: cmd
  3. Press Enter
10 Essential Commands:
cd DesktopGo to Desktop folder
dirList files in folder
mkdir NewFolderCreate new folder
cd ..Go up one folder
clsClear screen
python script.pyRun Python script
del file.txtDelete a file
copy file.txt backup.txtCopy file

⚠️ Golden Rules for Command Line Safety

  • 1.Never run commands you don't understand
  • 2.Read what it does first - Google unfamiliar commands
  • 3.Check the source is trusted - Don't copy from random websites
  • 4.Start with simple commands - Learn basics first
  • 5.Google error messages - Someone else had same issue
💡

Why Command Line Matters for AI:

Many AI tools use command line because it's faster and more powerful than clicking buttons. Once you know 10 basic commands, you can do anything!

🔧 Troubleshooting Common Problems

Problem 1: "Python not recognized"

❌ ERROR:

'python' is not recognized as an internal or external command

✅ SOLUTIONS:

  1. Reinstall Python, CHECK "Add Python to PATH" box during installation
  2. Restart your computer after installation
  3. Try python3 instead of python
  4. Manual PATH fix: Search "Environment Variables" → Edit PATH → Add Python folder

Problem 2: "Out of memory"

❌ ERROR:

Error: Out of memory / Killed / Process terminated

✅ SOLUTIONS:

  1. Use smaller model: Try 3B model instead of 7B
  2. Close all other programs (browser, apps, etc.)
  3. Restart your computer to free up memory
  4. Check model size vs your RAM: 7B models need 8GB+ RAM
  5. Consider upgrading RAM if running many AI tasks

Problem 3: "Model won't download"

✅ SOLUTIONS:

  1. Check your internet connection is stable
  2. Check disk space: You need 2x the model size free (7B model = ~14GB needed)
  3. Try a different smaller model first
  4. Use VPN if you're in a restricted region
  5. Download manually from Hugging Face website if needed

Problem 4: "Everything is slow"

Without GPU (CPU only):

1-2 words/second is NORMAL

This is expected behavior

With GPU:

10-30 words/second expected

Much faster performance

TO SPEED UP:

  • Check if GPU is being used (look for CUDA/ROCm in logs)
  • Update graphics drivers to latest version
  • Use smaller quantized models (Q4_K_M or Q5_K_M)
  • Close background programs and browser tabs

Problem 5: "Can't install software"

✅ SOLUTIONS:

  1. Check if you have administrator rights on the computer
  2. Disable antivirus temporarily (re-enable after install)
  3. Right-click installer → "Run as Administrator" (Windows)
  4. Check disk space: Need at least 10GB+ free space
  5. Download fresh installer file (previous one may be corrupted)

Problem 6: GPU not detected

  • Update NVIDIA/AMD drivers
  • Check CUDA or ROCm is installed
  • Verify GPU compatibility with AI tools
  • Check GPU shows in Device Manager (Windows)

Problem 7: "Command not found"

  • Check PATH environment variable
  • Close and restart terminal/command prompt
  • Restart computer
  • Reinstall software if problem persists

💡 Pro Troubleshooting Tips:

  • •Copy exact error message and Google it - someone else has solved it
  • •Restart is the first solution for 60% of problems
  • •Check if problem exists with simpler/smaller model first
  • •Join r/LocalLLaMA on Reddit - friendly community that helps beginners

Frequently Asked Questions

What computer do I need to run AI software?

Any modern computer with 8GB+ RAM and 50GB of free storage space can run AI software. Windows, Mac, and Linux are all supported. You don't need a powerful gaming computer - most standard laptops from the last 5 years work perfectly for AI applications.

💻 Tech Tip: If your computer can run modern web browsers smoothly, it can probably run AI tools.

How much does it cost to get started with AI?

You can start completely free using tools like ChatGPT (free version), Ollama (local AI), and Python. Total startup cost is $0. Optional paid tools like Midjourney ($10/month) or ChatGPT Plus ($20/month) can enhance your capabilities but aren't required to begin learning.

🆓 Free Start: Many AI professionals built their businesses using only free tools initially.

Do I need programming skills to use AI?

No, you don't need programming skills to start using AI. Most AI tools are web-based or have graphical interfaces. Programming becomes valuable later for custom solutions, but you can achieve impressive results with zero coding knowledge using tools like ChatGPT, Midjourney, and LM Studio.

🎨 Creative First: Focus on AI applications first, learn programming later if needed for custom projects.

How long does setup take?

Basic setup takes 30 minutes or less. This includes downloading and installing your first AI tool, creating accounts, and running your first AI generation. Most students are actively using AI within their first hour, with complete setup finished by day 3.

⏱️ Quick Win: You'll see your first AI-generated content within 10 minutes of starting.

What if I run into technical problems?

This chapter includes step-by-step troubleshooting guides for the most common issues: installation errors, slow performance, connection problems, and account setup difficulties. Additionally, all AI tools have extensive help documentation and active user communities where you can get support.

🛠️ Support Available: Every problem has a solution - we've documented the most common ones.
