SciPy

Warnings

• breaking SciPy 1.17.1 requires Python 3.11 or higher.
  Fix: Upgrade your Python installation to version 3.11 or later.
• gotcha Ensure that NumPy is installed before SciPy, as SciPy depends on NumPy for array operations.
  Fix: Install NumPy first using 'pip install numpy'.

Install

• pip install scipy Install SciPy

Imports

• shortest_path

  from scipy.sparse.csgraph import shortest_path

  Ensure correct submodule import for shortest_path function.
• geometric_slerp

  from scipy.spatial import geometric_slerp

  Ensure correct submodule import for geometric_slerp function.

Quickstart

This example demonstrates how to compute the shortest path distances in a graph using SciPy's sparse graph module.

import numpy as np
from scipy.sparse.csgraph import shortest_path

# Create a sample graph as a 2D NumPy array
graph = np.array([[0, 1, 2], [1, 0, 0], [2, 0, 0]])

# Compute the shortest path distances
dist_matrix, predecessors = shortest_path(graph, return_predecessors=True)

print('Shortest path distance matrix:')
print(dist_matrix)
