Where should I start?

Begin with NumPy and Pandas for data, then scikit-learn for classic ML before deep learning frameworks.

Do I need to master all these libraries?

No — pick a lane: NumPy + pandas for data work, then either PyTorch (research, custom models) or scikit-learn (classical ML) depending on your goals. Most practitioners use three or four libraries daily and look the rest up as needed.

Do I still need these libraries in the LLM era?

More than ever. Every serious LLM project still runs on Pandas for data preparation, NumPy under the hood of embeddings, and scikit-learn for baselines and evaluation. Classic ML also stays cheaper and more explainable for tabular problems where an LLM would be overkill.
