Error Writing Frames - Demo Code Does Not Work

[suhailgupta03]

The example code itself does not work. I have added the errors below.

# Author: Bishal Sarang

# Import Visualiser class from module visualiser
from visualiser.visualiser import Visualiser as vs

# Add decorator
# Decorator accepts optional arguments: ignore_args , show_argument_name, show_return_value and node_properties_kwargs
@vs(node_properties_kwargs={"shape":"record", "color":"#f57542", "style":"filled", "fillcolor":"grey"})
def fib(n):
    if n <= 1:
        return n
    return fib(n=n - 1) + fib(n=n - 2)

def main():
    # Call function
    print(fib(n=6))
    # Save recursion tree to a file
    vs.make_animation("fibonacci.gif", delay=2)

if __name__ == "__main__":
    main()

When you run the above code, it gives this:

8
Starting to make animation
Writing fibonacci.png failed
Writing frames....
Error writing frames
Writing gif...
Error saving gif.

Creates a gif of 0 bytes.
