<｜begin▁of▁sentence｜>### Instruction:
Given a graph you can read from littleballoffur15.sparse6, can you use LoopErasedRandomWalkSampler to generate a tree subgraph with exactly 10 nodes using a loop-erased random walk?
### Response:
import networkx as nx
from littleballoffur.exploration_sampling import LoopErasedRandomWalkSampler
G = nx.read_sparse6('littleballoffur15.sparse6')
sampler = LoopErasedRandomWalkSampler(number_of_nodes=10)
sampler_G = sampler.sample(G)
print(sampler_G.edges(), sampler_G.nodes())
