HELP, I$\text{'}$m trying to make a Human Vasculature in $3$D using python for my AI final project. Please help me fix this code.

import vtk

import numpy as np

# Generate synthetic $3$D vasculature data $($example$)$

def generate$\_$synthetic$\_$vasculature$()$:

# Create a $3$D numpy array representing the vasculature

vasculature $=$ np$.$zeros$((100,100,100),$ dtype$=$np$.$uint$8)$

# Add some vessels $($for demonstration purposes$)$

vasculature$[20$:$30,40$:$60,40$:$60]=255$

vasculature$[60$:$70,20$:$80,20$:$80]=255$

return vasculature

# Convert numpy array to VTK image data

for i in range$($numpy$\_$array.shape$[0])$:

for j in range$($numpy$\_$array.shape$[1])$:

for k in range$($numpy$\_$array.shape$[2])$:

vtk$\_$image.SetScalarComponentFromFloat$($i$,$ j$,$ k$,0,$ numpy$\_$array$[$i$,$ j$,$ k$])$

return vtk$\_$image

# Create a VTK volume mapper

mapper $=$ vtk$.$vtkSmartVolumeMapper$()$

mapper.SetBlendModeToComposite$()$

return mapper

# Create a VTK volume property

def create$\_$volume$\_$property$()$:

property $=$ vtk$.$vtkVolumeProperty$()$

property.ShadeOff$()$

property.SetInterpolationTypeToLinear$()$

return property

# Create a VTK volume actor

def create$\_$volume$\_$actor$($mapper$,$ property$)$:

actor $=$ vtk$.$vtkVolume$()$

actor.SetMapper$($mapper$)$

actor.SetProperty$($property$)$

return actor

# Main function to create and visualize the vasculature

def visualize$\_$vasculature$($vasculature$)$:

# Add the volume actor to the renderer

renderer.AddActor$($actor$)$

renderer.SetBackground$(0\mathrm{.}1,0\mathrm{.}2,0\mathrm{.}4)$

# Set camera position and render

renderer.ResetCamera$()$

render$\_$window.Render$()$

# Start the interaction

render$\_$window$\_$interactor.Start$()$

# Main function

def main$()$:

# Generate synthetic vasculature data

vasculature $=$ generate$\_$synthetic$\_$vasculature$()$

# Visualize the vasculature

visualize$\_$vasculature$($vasculature$)$
