Mar 2026 15:49:11 +0100 Subject: [PATCH 3/4] claude suggested speed/memory improvements: MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit #1 — read_hdf5_datasets: eliminate np.append in loop Replaced the per-file np.append pattern (which reallocates the full array on every call) with collecting chunks in a list and calling np.concatenate once at the end. For N files of M points each, this reduces allocations from O(N) full-array copies to one. #2 — fill_nan_with_neighbor_mean: vectorise triple-nested loop Replaced the Python for i / for j / for neighbour loop with scipy.ndimage.generic_filter, which operates in compiled C over the entire array in one pass. #3 — plot_2D_posterior: deduplicate sorted-histogram computation The same np.sort + np.cumsum + normalisation was computed twice in the same function call (once for CR masking, once for contour drawing). Now initialised to None and computed at most once, with the second use reusing the cached result. #4 — Replace deepcopy with shallow copies throughout - Numeric bounds (xy_bounds, x_bounds): replaced with [list(b[0]), list(b[1])] / list(b) — sufficient since only scalars are mutated. - requested_datasets (list of immutable tuples): replaced with list(). - NumPy array slices (y_data[mask], z_data[mask], etc.): removed entirely — fancy indexing already returns a copy. - deepcopy(y_data) in posterior shading: replaced with y_data.copy(). - Removed the now-unused deepcopy import. #5 — plot_1D_profile confidence band loop: single mask computation The boolean mask (x_values > x_start) & (x_values < x_end) was evaluated twice per segment (once for x, once for y) and converted through a Python list. Now computed once with np.concatenate instead of list wrapping. #6 — bin_and_profile_2D: nested loop → np.meshgrid Replaced the double Python loop over bin centres with a single np.meshgrid call + .ravel(), keeping the same flat-array layout (index = y_bin_index * n_xbins + x_bin_index). Bonus — Module-level np.finfo constants np.finfo(float).max and .eps (called ~20 times across function signatures and bodies) are now computed once at import time as _FLOAT_MAX and _FLOAT_EPS. --- gambit_plotting_tools/gambit_plot_utils.py | 185 +++++++++++---------- 1 file changed, 97 insertions(+), 88 deletions(-) diff --git a/gambit_plotting_tools/gambit_plot_utils.py b/gambit_plotting_tools/gambit_plot_utils.py index 77c04a4..f50fbbb 100644 --- a/gambit_plotting_tools/gambit_plot_utils.py +++ b/gambit_plotting_tools/gambit_plot_utils.py @@ -1,4 +1,4 @@ -from copy import copy, deepcopy +from copy import copy from collections import OrderedDict import os import shutil @@ -16,6 +16,10 @@ from gambit_plotting_tools.gambit_colormaps import gambit_std_cmap import gambit_plotting_tools.gambit_plot_settings as gambit_plot_settings +# Module-level float constants to avoid repeated np.finfo() calls +_FLOAT_MAX = np.finfo(float).max +_FLOAT_EPS = np.finfo(float).eps + # Check if LaTeX rendering is supported by looking for the commands 'latex', 'dvipng' and 'gs' tex_required_tools = ("latex", "dvipng", "gs") @@ -143,7 +147,7 @@ def read_hdf5_datasets(hdf5_file_and_group_names, requested_datasets, filter_inv # "_isvalid" dataset corresponding to each requested dataset isvalid_keys = [] if filter_invalid_points: -

read_hdf5_datasets: HDF5 file handle now uses a with context manager — file is guaranteed to close even if an exception occurs during reading - 7 functions: mutable default [] arguments for confidence_levels, credible_regions, and contour_levels changed to None with a guard at the top of each function body Dead code removal - bin_and_profile_1D: removed 7 lines of commented-out old binning implementation - create_empty_figure_1D / 2D: removed unused figheight_figwidth_ratio variable - plot_1D_profile, plot_1D_delta_chi2, plot_2D_profile, plot_2D_posterior, plot_1D_posterior, plot_2D_scatter: removed unused n_pts assignments - plot_1D_profile: removed redundant double-initialisation of cl_lines_y_vals Style fixes - plot_2D_profile, nearest_neighbor_averaging: != None → is not None - plot_1D_profile, plot_1D_delta_chi2, plot_2D_profile, plot_2D_posterior, plot_2D_scatter: -> None return annotations corrected to -> tuple: - plot_conditional_profile_intervals, plot_conditional_credible_intervals: two previously-missed fontsize - 3 hardcodings fixed to use plot_settings["colorbar_tick_label_fontsize_offset"] New private helpers (5 functions added before create_empty_figure_1D) - _expand_2D_bounds(xy_bounds) — replaces 4-line epsilon-expansion block, used in 5 functions - _draw_threshold_lines(...) — replaces duplicated CL/CR line-drawing loops in plot_1D_profile and plot_1D_delta_chi2 - _setup_colorbar(...) — replaces ~15-line colorbar setup block in 5 functions - _plot_marker(...) — replaces 2–5-line ax.scatter marker calls in 8 places - _x_condition_mask(...) — replaces duplicated bin-masking if/elif blocks in both conditional-interval functions --- gambit_plotting_tools/gambit_plot_utils.py | 455 ++++++++------------- 1 file changed, 169 insertions(+), 286 deletions(-) diff --git a/gambit_plotting_tools/gambit_plot_utils.py b/gambit_plotting_tools/gambit_plot_utils.py index f50fbbb..7c64f97 100644 --- a/gambit_plotting_tools/gambit_plot_utils.py +++ b/gambit_plotting_tools/gambit_plot_utils.py @@ -21,6 +21,93 @@ _FLOAT_EPS = np.finfo(float).eps +def _expand_2D_bounds(xy_bounds): + """Expand 2D plot bounds by machine epsilon on all sides to avoid edge effects.""" + xy_bounds[0][0] -= _FLOAT_EPS + xy_bounds[0][1] += _FLOAT_EPS + xy_bounds[1][0] -= _FLOAT_EPS + xy_bounds[1][1] += _FLOAT_EPS + + +def _draw_threshold_lines(ax, x_min, x_max, levels, threshold_y_vals, color, label_suffix, plot_settings): + """Draw horizontal threshold lines (CL or CR) with text labels on a 1D plot.""" + linewidths = cycle(list(plot_settings["contour_linewidths"])) + for level, y_val in zip(levels, threshold_y_vals): + ax.plot([x_min, x_max], [y_val, y_val], color=color, + linewidth=next(linewidths), + linestyle=plot_settings["confidence_level_linestyle"]) + label_text = f"${100 * level:.1f}\\%\\,${label_suffix}" + ax.text(plot_settings["cl_label_x_offset"], y_val, label_text, + ha=plot_settings["cl_label_ha"], va=plot_settings["cl_label_va"], + fontsize=plot_settings["header_fontsize"], color=color, + transform=ax.transAxes) + + +def _setup_colorbar(fig, ax, im, color_bounds, log_scale_colorbar, cbar_label, fontsize, plot_settings): + """Create and configure a colorbar, returning (cbar_ax, cbar).""" + cbar_ax = inset_axes(ax, width=plot_settings["colorbar_width"], + height=plot_settings["colorbar_height"], + loc=plot_settings["colorbar_loc"], + borderpad=plot_settings["colorbar_borderpad"]) + cbar = fig.colorbar(im, cax=cbar_ax, orientation=plot_settings["colorbar_orientation"]) + cbar.outline.set_edgecolor(plot_settings["framecolor_colorbar"]) + cbar.outline.set_linewidth(plot_settings["framewidth"]) + + if log_scale_colorbar: + cbar.locator = matplotlib.ticker.LogLocator() + cbar.update_ticks() + elif color_bounds is not None: + cbar.set_ticks(np.linspace(color_bounds[0], color_bounds[1], + plot_settings["colorbar_n_major_ticks"]), minor=False) + minor_tick_values = np.linspace(color_bounds[0], color_bounds[1], + plot_settings["colorbar_n_minor_ticks"]) + cbar.set_ticks(minor_tick_values[(minor_tick_values >= color_bounds[0]) & + (minor_tick_values <= color_bounds[1])], minor=True) + + offset = plot_settings["colorbar_tick_label_fontsize_offset"] + cbar.ax.tick_params(which="major", labelsize=fontsize -
