<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from littleballoffur2.sparse6, can you use NonBackTrackingRandomWalkSampler to sample a subgraph that avoids the tottering behaviour induced by backtracking steps and captures 10 nodes?
### Response:
import networkx as nx
from littleballoffur import NonBackTrackingRandomWalkSampler
G = nx.read_sparse6('littleballoffur2.sparse6')
sampler = NonBackTrackingRandomWalkSampler(number_of_nodes=10)
sampler_G = sampler.sample(G)
print(sampler_G.edges())
print(sampler_G.nodes())
