    Hi. I need to implement simple terrain generator using python and matplotlib. It must use Perlin noise with parameters which define variety of terrain and its smoothness.

    Here's a basic implementation of a terrain generator using Perlin noise and Matplotlib:

    import matplotlib.pyplot as plt
    from noise import pnoise2
    
    # Set dimensions of terrain
    width = 800
    height = 800
    
    # Set generator parameters
    octaves = 6
    persistence = 0.5
    lacunarity = 2.0
    scale = 200.0
    
    # Create empty terrain array
    terrain = np.zeros((height, width))
    
    # Generate terrain using Perlin noise
    for i in range(height):
        for j in range(width):
            terrain[i][j] = pnoise2(j/scale, i/scale, octaves=octaves, persistence=persistence, lacunarity=lacunarity, repeatx=width, repeaty=height, base=0)
    
    # Plot terrain
    plt.imshow(terrain, cmap='terrain')
    plt.show()
    

    Here, the noise library is used to generate Perlin noise. The height and width parameters define the dimensions of the terrain. The octaves, persistence, lacunarity, and scale parameters all affect the characteristics of the noise and the resulting terrain. You can adjust these to achieve different terrain shapes and smoothness.

    The final output is a 2D array of values, which is plotted using Matplotlib's imshow() function with the 'terrain' color map.

    I hope this helps! Let me know if you have any questions or need further assistance.

    Your code doesn't work. I get this error:

    Traceback (most recent call last):
      File "/mnt/d/Programming/fbgbgb/lol.py", line 15, in <module>
        terrain = np.zeros((height, width))
                  ^^
    NameError: name 'np' is not defined

    Apologies, I accidentally omitted the import of the numpy library, so you should include this additional line at the start:

    import numpy as np
