How did you install OSMnx?

Pip

Problem description

import networkx as nx import osmnx as ox import matplotlib.pyplot as plt import matplotlib bounds = [114.05, 22.55, 114.07, 22.57] north, south, east, west = bounds[3], bounds[1], bounds[2], bounds[0] G = ox.graph_from_bbox(north, south, east, west, network_type='drive') ox.plot_graph(G) ImportError: matplotlib must be installed as an optional dependency for visualization I have matplotlib but I can't cite it.How to solve this problem.

Complete minimal reproducible example

import networkx as nx
import osmnx as ox
import matplotlib.pyplot as plt
import matplotlib
bounds = [114.05, 22.55, 114.07, 22.57] 
north, south, east, west = bounds[3], bounds[1], bounds[2], bounds[0] 
G = ox.graph_from_bbox(north, south, east, west, network_type='drive')
ox.plot_graph(G)

You can solve this problem by following the installation instructions.

Looking through the environment packages you pasted, you can see OSMnx isn't there.
