Code Review
This pull request performs extensive cleanup by removing unused imports across the project, updating the .gitignore, and refining test scripts. It also introduces documentation for the RemoveBackgroundAndResizeNode and replaces hardcoded temporary paths with a more robust solution. Feedback was provided to correct the parameter table in the README documentation and to reorganize imports and sys.path modifications in grabcut_nodes.py to follow PEP 8 standards.

The parameter table for RemoveBackgroundAndResizeNode is incorrect and does not match the implementation in RemoveBackgroundAndResizeNode.py. The node actually uses parameters like tolerance, foreground_bias, color_clusters, output_size, and scaling_method instead of width, height, and upscale_method.

Standard library imports and sys.path modifications should be placed at the top of the file to adhere to PEP 8 and ensure they are available for subsequent imports. This also avoids the need for # noqa: E402.

These lines should be removed as they have been moved to the top of the file to comply with PEP 8.

__init__.py (1)
3-6: Thenoqadirective is appropriate, but consider simplifying the pattern.The
# noqa: F401directive correctly documents that thesklearnimport is intentionally unused (it's only for the availability check). However, note that according to the coding guidelines, flake8 should only check E9,F63,F7,F82 error codes—F401 isn't in that list, so this directive may be unnecessary if you're following the configured linting rules.Additionally,
SKLEARN_AVAILABLEis assigned on lines 4 and 6 but never actually used within this file. The variable isn't referenced anywhere after being set and isn't exported in__all__. Sincebackground_remover.pymaintains its ownSKLEARN_AVAILABLEflag (as shown in the context snippets), you could simplify this pattern.♻️ Optional refactor to remove unused variable
# Check for optional dependencies and provide helpful warnings try: - import sklearn # noqa: F401 - SKLEARN_AVAILABLE = True + import sklearn # noqa: F401 # Import to verify availability except ImportError: - SKLEARN_AVAILABLE = False print("\n" + "="*70) print("⚠️ TransparencyBackgroundRemover: scikit-learn not installed!") print("="*70)This removes the unused variable while keeping the availability check and warning functionality intact.
As per coding guidelines: "Run flake8 linting with E9,F63,F7,F82 error codes" - F401 is not in this list, so flake8 configured per guidelines wouldn't flag this unused import.

Add a language identifier to the project-structure code fence.
This fence is missing a language tag and will trip markdownlint MD040.
