<｜begin▁of▁sentence｜>### Instruction:
As a jazz musician, you've been using NetworkX to map out the connections between various musicians in the jazz scene. You've customized your graph by attaching an 'attribute_collector' to each musician's vertex. Now, you're curious about how extensive your attribute collection is for each musician. Using the `AttributeCollectorBase` class, you want to determine the total number of attributes collected for each vertex in your jazz network.
### Response:
from igraph import Graph

# Load or create a graph
g = Graph.Erdos_Renyi(n=100, m=200)

# Assume 'AttributeCollectorBase' is part of a given class for collecting attributes
collector = g.vs['attribute_collector']

# Get the number of collected attributes
number_of_attributes = len(collector)

print(number_of_attributes)
