<｜begin▁of▁sentence｜>### Instruction:
Given a networkx erdos_renyi_graph with parameters n=800, p=0.1, can you use ShortestPathSampler to sample a subgraph which has 20 nodes by selecting random shortest paths between pairs of nodes?
### Response:
import networkx as nx
from littleballoffur import ShortestPathSampler

G = nx.gnp_random_graph(n=800, p=0.1)

sampler = ShortestPathSampler(20, seed=123)

sampler_G = sampler.sample(G)

print(sampler_G)
