PyTorch
Train and fine-tune models — the ML foundation behind MLOps and many LLM workflows.
Maturity level: L2 — Can Build
Six perspectives on PyTorch
Roadmap
Learn after Python — before MLflow and model serving make sense.
Architecture
Training layer that feeds experiment tracking and deployment pipelines.
Company
Expected for ML engineer and MLOps roles; useful for LLMOps fine-tuning work.
Projects
Train at least one model end-to-end before automating the pipeline.
Interview
Training fundamentals, not just tool names.
Career
Credibility with ML teams — you understand what the pipeline is shipping.
What & Why
What: Deep learning framework for building, training, and exporting neural network models.
Why: MLOps engineers need to understand training loops, checkpoints, and exports — not just pipelines around models others built.
Build this
Train a classifier, track metrics, export to ONNX, and serve via an API.
Production reality
- ! OOM during training
- ! Non-determinism
- ! Checkpoint corruption
- ! Train/serve skew
Interview preparation
- Explain training vs inference graph
- How do you debug NaN losses?
- Fine-tuning vs training from scratch
