Why can Unsloth fine-tune LLMs like Llama 3.1 8B, Llama 3.3 70B, and Qwen 3.5 MoE 2x faster with 70% less VRAM than ...

Before any math: install PyTorch, import it, and print your first tensor — then answer the question tutorials skip. What actually sits ...

In this PyTorch Transfer Learning tutorial, we'll build a complete image classifier step by step using a pretrained ResNet50 model.

Train your first computer vision model in PyTorch — from a blank notebook to a CNN that can say frog, not cat. In this beginner ...

Conv, ReLU, pool, repeat — then flatten and a linear classifier on the end. This video assembles a real CNN in PyTorch from five ...

Your first guess about what's slow is almost always wrong, and your first stopwatch is almost always lying — because a GPU call ...

Fit a line with nothing but tensors, a loss, and the training loop — no nn.Module, no DataLoader, nothing hidden. That is the point: ...

What is PyTorch? A Complete Beginner's Guide (10-Minute Tutorial) Want to learn how computers recognize images, ...

Training is worth nothing until the weights survive the process that made them — and a saved model is not a program, it is a ...

90% of deep learning bugs are shape bugs. This episode gives you the exact linear algebra you actually need — scalars, vectors, ...

The bottleneck is rarely where you think it is — and in a beginner's training loop, it's often not the GPU at all. This video profiles a ...

Three error messages account for most of the pain in PyTorch — shape mismatch, device mismatch, and a .grad that is None.

The gradient tells you which way is downhill. The optimizer is the rule that decides how far to actually step — and that one ...

Five lines, in this order, every single time — and every remaining video in this course is these five lines with more furniture around ...

Every future episode in this series requires one thing: a working deep learning environment. This is the exact setup I use ...

Nobody differentiates a neural network by hand. PyTorch records every operation you do to a tensor, then plays that record ...

The bus between your CPU and GPU really is the slowest link in the machine — that part is true, and this video measures it: 4.72 ...

Flatten a photo into one long vector and you throw away the only thing that made it a photo: that two pixels sitting next to each ...

Build a full Fashion-MNIST classifier in PyTorch — the whole pipeline (data → DataLoader → model → loss → optimizer → save) ...

Most tutorials show you how to write PyTorch syntax, but they rarely explain what actually happens under the hood when that ...
