Research direction

Work in src/data.py, adding load_raw_images(root) and get_dataset(). Issue #5 is listed as a dependency, so check whether it has landed and what it provides for locating the 256x256 originals before you start. Done means get_dataset() returns X with shape (3000, 64, 64, 3) and labels 0/1/2 with 1000 each, and the data/animals64.npz cache is written once and reused on later calls.

Written by the indexing model from the issue text.

Description

data

Resize the 256x256 originals to 64x64 (bilinear) to emulate an edge camera; cache to avoid re-resizing.

Files: src/data.py

Tasks
  • load_raw_images(root) -> X uint8 (N,64,64,3), y int64 (N,)
  • get_dataset() builds data/animals64.npz once, loads it afterwards
  • Convert every image to RGB before resizing
Done when

get_dataset() returns X with shape (3000, 64, 64, 3) and labels 0/1/2, 1000 each.
