Verified usage

Verified import paths — ran on the pinned version, not inferred.

Graph

✓ from networkx import Graph

Direct import of Graph class from networkx module.

add_path

✓ G.add_path([0, 1, 2, 3])

Use the method directly on a Graph instance.

A simple example to create a graph, add nodes and edges, and visualize it using matplotlib.

import networkx as nx # Create an empty graph G = nx.Graph() # Add nodes and edges G.add_nodes_from([1, 2, 3]) G.add_edges_from([(1, 2), (2, 3)]) # Draw the graph import matplotlib.pyplot as plt nx.draw(G, with_labels=True) plt.show()

Debug

Known issues

breakingThe 'release' module has been removed in NetworkX 3.0. Direct import of 'release' will result in an ImportError.

fix

Remove the import statement 'from networkx import release' from your code.

affects: >=3.0

deprecatedThe 'add_path' function is now a method of the Graph class and should be called on a Graph instance.

fix

Replace 'networkx.add_path(G, [0, 1, 2, 3])' with 'G.add_path([0, 1, 2, 3])'.

affects: >=3.0

gotchaEnsure that all optional dependencies (numpy, scipy, matplotlib, pandas) are installed for full functionality, especially for graph visualization and advanced computations.

fix

Install optional dependencies using 'pip install networkx[default]'.

affects: >=3.0

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'networkx'

The NetworkX library is not installed in the current Python environment or the environment is not correctly activated.

fix

Run `pip install networkx` in your terminal or command prompt. If using Anaconda, use `conda install networkx` instead.

AttributeError: module 'networkx' has no attribute 'info'

The `info()` method was removed in NetworkX 3.0.0; direct attribute access or other specific functions should be used instead for graph summaries.

fix

Access graph properties directly (e.g., `G.number_of_nodes()`, `G.number_of_edges()`) or print the graph object `print(G)` for a basic summary. If a detailed summary is needed for compatibility with older code, consider `nx.graph_info(G)` if available, or update the code to use newer API features.

AttributeError: module 'networkx' has no attribute 'from_pandas_edgelist'

The `from_pandas_edgelist` function was introduced in NetworkX version 2.0.0. This error occurs when using an older version of the library.

fix

Upgrade NetworkX to version 2.0 or newer by running `pip install --upgrade networkx` in your terminal or command prompt.

networkx.exception.NetworkXError: Edge tuple ('A',) must be a 2-tuple or 3-tuple.

This error occurs when the `add_edges_from()` method receives an iterable where individual elements are not valid 2-tuples (source, target) or 3-tuples (source, target, data_dict) representing edges.

fix

Ensure the input to `add_edges_from` is a list or iterable of tuples, where each tuple strictly contains two (source, target) or three elements (source, target, edge_attributes), e.g., `G.add_edges_from([(1, 2), (2, 3, {'weight': 0.5})])`.

SyntaxError: invalid syntax (when running `pip install networkx`)

The `pip install` command is being executed within the Python interpreter's interactive shell, not directly in the system's command prompt or terminal.

fix

Exit the Python interpreter (by typing `exit()` and pressing Enter) and then run `pip install networkx` directly in your operating system's command prompt (Windows) or terminal (macOS/Linux).
