From 31a6f51989059688fa9bf6dae3a2451a4b4a4555 Mon Sep 17 00:00:00 2001 From: Arvind Iyer Date: Tue, 14 Jul 2026 17:29:30 -0400 Subject: [PATCH] perf: lazy-load plotting functions, drop unused seaborn dependency selectsim/__init__.py eagerly imported selectsim.plotting at package import time, which pulls in matplotlib and scipy (used nowhere outside plotting.py) even for callers who only call selectX() and never plot anything. Plotting functions (obs_exp_scatter, ridge_plot_ed, oncoprint, etc.) are now resolved lazily on first access via a PEP 562 module __getattr__ instead -- same ss. usage, just deferred. Measured: `import selectsim` dropped from ~1.5s to ~0.6s. Also drops the seaborn dependency: it was listed in pyproject.toml and mentioned in a couple of docstrings, but grep confirms it was never actually imported or used anywhere in the codebase. Updated the introduction tutorial's Session info cell to match (it printed seaborn.__version__). Bumped to 0.3.1; full test suite (148 tests) and the tutorial notebook both verified passing after the change.
