<｜begin▁of▁sentence｜>### Instruction:
As a data scientist, you've been working on a project involving visualizing a complex network of relationships between various data points using NetworkX. In one task, you're tasked with coloring each node in the graph with a unique color from the RainbowPalette to enhance the visual representation of the network. However, after completing this task, you realize the need to reset or clear the cache of the RainbowPalette instance to ensure that any old color state doesn't affect future operations or visualizations. How would you go about clearing the cache of the RainbowPalette instance in NetworkX to ensure its reusability for future tasks without any lingering effects from previous operations?
### Response:
from igraph.drawing.colors import RainbowPalette

# Create a RainbowPalette instance
palette = RainbowPalette()

# Use the palette for some operation (e.g., coloring nodes)

# ... your code for using the palette ...

# Clear the palette's cache when needed
clear_cache()
