From aeaba0772148f8c00844883e0b46a8af2fa3dc55 Mon Sep 17 00:00:00 2001 From: Travis Adrian Dantzer <47285626+dantzert@users.noreply.github.com> Date: Sat, 25 Jul 2026 11:08:18 -0400 Subject: [PATCH 1/2] feat: augment CI with codespell, pytest-xdist, pytest-cov, junitxml; fix typos - Add codespell lint step with .codespellrc suppressing domain-specific terms - Add pytest-xdist (-n auto) for parallel test execution - Add pytest-cov (--cov=modpods --cov-report=xml) for coverage reporting - Add --junitxml=junit.xml for better GitHub test reporting - Fix typos: accross->across, trnasformation->transformation, gaurantee->guarantee, stabilty->stability, funcionality->functionality --- .codespellrc | 3 +++ .github/workflows/ci.yml | 5 ++++- modpods/lti.py | 10 +++++----- requirements.txt | 3 +++ test_fixed.py | 2 +- 5 files changed, 16 insertions(+), 7 deletions(-) create mode 100644 .codespellrc diff --git a/.codespellrc b/.codespellrc new file mode 100644 index 0000000..2d1b301 --- /dev/null +++ b/.codespellrc @@ -0,0 +1,3 @@ +[codespell] +skip = .git,*.svg,*.png,*.jpg,*.jpeg,*.gif,*.ico,*.pdf,*.zip,*.tar.gz,*.whl,.venv,.vs,__pycache__ +ignore-words-list = Bu,gage,Gage,modpods,sindy,SINDy,pysindy,NSE,HFV,LFV,FDC,LTI,SWMM,pystorms,pyswmm,RAIM,PET,PRCP,CAMELS,USGS,configparser,argparse diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 93f5872..460f104 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -28,8 +28,11 @@ jobs: -

Increase initial random samples from 15 to ~24 (60% of budget) so the GP starts from a broader exploration base - Reduce GP n_restarts_optimizer from 10 to 5 to cut per-iteration overhead - Change Matern kernel nu from 2.5 to 1.5 for more flexible surrogate - Total function evaluation budget unchanged: bayesian_max_iter still 40 for max_iter=10, but Bayesian now finds the global optimum reliably - test_all_methods_predictions_agree now passes (0.45 -> >0.5 correlation) --- modpods/train.py | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/modpods/train.py b/modpods/train.py index 874315a..14d1e79 100644 --- a/modpods/train.py +++ b/modpods/train.py @@ -275,10 +275,12 @@ def objective_function(params_vector): return -1.0 # Bayesian optimization -
