<｜begin▁of▁sentence｜>### Instruction:
Given an Erdos-Renyi graph with 10 vertices and 20 edges, can you use the similarity_dice function in igraph to calculate the Dice similarity coefficient for all pairs of vertices in the graph?
### Response:
import igraph as ig

# Create a graph
g = ig.Graph.Erdos_Renyi(n=10, m=20)

# Calculate Dice similarity coefficient for all pairs of vertices
similarity_matrix = g.similarity_dice()

# Show the similarity matrix
print(similarity_matrix)
