To resolve the `ModuleNotFoundError` for `networkx` in Pyodide, install the package before importing it. Here’s the corrected code: ```python # Install required packages import micropip await micropip.install('networkx') # Install NetworkX await micropip.install('matplotlib') # Ensure Matplotlib is installed # Original code import numpy as np import networkx as nx import matplotlib.pyplot as plt class EntanglementGraph: def __init__(self, num_nodes): self.graph = nx.random_geometric_graph(num_nodes, radius=0.3) self.states = np.random.rand(num_nodes, 2) # Qubit states def entangle(self): for edge in self.graph.edges: # Apply CNOT gate to entangle connected nodes control, target = edge self.states[target] = np.dot(self.states[control], self.states[target]) def plot(self): nx.draw(self.graph, node_color=[np.linalg.norm(s) for s in self.states], cmap='viridis') plt.show() # Run simulation g = EntanglementGraph(10) g.entangle() g.plot() ``` **Key Fixes**: 1. Added `await micropip.install('networkx')` to install NetworkX 2. Added `await micropip.install('matplotlib')` to ensure plotting works 3. Added `await` to ensure installation completes before imports This will resolve the missing module errors. Note that Pyodide requires `await` for package installation in asynchronous contexts.
