Training Neural Networks with PyTorch

You need a hands-on framework to turn intuition into working, trainable models.

1

Learn it

Work through the official PyTorch 60 Minute Blitz to learn tensors, autograd, nn.Module, and a full training loop, culminating in a CIFAR-10 image classifier. Optionally anchor the concepts with Andrew Ng's foundational course (audit for free).

By the end you’ll be able to

  • Build models with tensors, autograd, and nn.Module
  • Write a training loop with an optimizer and loss

Free resources

2

Practice

Follow the Blitz to train the CIFAR-10 classifier, then modify the training loop to log per-epoch loss and validation accuracy.

3

Build it — your output

A working PyTorch training script that trains a classifier and prints an accuracy metric.

4

Prove it — check yourself

You’re ready to move on when you can honestly say yes to each:

  • Can you explain what optimizer.zero_grad(), loss.backward(), and optimizer.step() each do?
  • Can you split data into train/validation and report validation accuracy?
  • Can you move a model and tensors to GPU?

Do it with AI

Use a free AI tool as your tutor and pair-programmer. Copy a prompt below into Claude, ChatGPT, or Gemini (for building, try Cursor or Copilot).

The habit: Try it yourself first — a little struggle is where the learning actually happens. Then ask for a hint before the answer — never copy blindly.

  • Understand itClaude / ChatGPT / Gemini

    I'm a beginner learning "Training Neural Networks with PyTorch". Explain it in simple terms with a real-world analogy, then ask me ONE question to check my understanding — don't reveal the answer.

  • PracticeClaude / ChatGPT / Gemini

    Give me 3 short practice problems on "Training Neural Networks with PyTorch" (my goal: build models with tensors, autograd, and nn.module), from easy to hard. Don't include the solutions yet — I'll try them first, then ask you to check.

  • Get unstuckClaude / ChatGPT / Gemini

    I'm stuck on this exercise about "Training Neural Networks with PyTorch": [paste your attempt here]. Give me ONE small hint to move forward — do NOT give me the full solution.

  • Build & reviewCursor / Copilot

    Here is my work for a "Training Neural Networks with PyTorch" task: [paste your code or answer]. Review it: point out what's wrong and WHY, and suggest improvements — but let me make the fixes myself.

  • Prove itClaude / ChatGPT / Gemini

    Quiz me on "Training Neural Networks with PyTorch". Ask me 5 questions one at a time, wait for my answer each time, then tell me if I'm right and briefly why.
