<｜begin▁of▁sentence｜>### Instruction:
As a Robotics Technician, you are tasked with installing, maintaining, and repairing robotic systems and equipment in manufacturing or industrial settings. Today, you have been given an erdos-renyi graph with 200 nodes and a probability value of 0.2, which represents connections between nodes in a complex manufacturing network. Your task is to use the RandomWalkWithRestartSampler to sample a subgraph with 50 nodes and then calculate the average shortest path length in the sampled graph.
### Response:
import networkx as nx
from littleballoffur import RandomWalkWithRestartSampler

G = nx.gnp_random_graph(n=200, p=0.2)

sampler = RandomWalkWithRestartSampler(number_of_nodes=50, seed=123, p=0.05)

sampler_G = sampler.sample(G)

result = nx.average_shortest_path_length(sampler_G)

print(result)
