Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

pnoise2

✓ from noise import pnoise2

✗ import noise; noise.pnoise2(...)

pnoise2 is a function, not a method; importing directly is more explicit.

pnoise3

✓ from noise import pnoise3

PerlinNoise

✓ from noise import PerlinNoise

Basic usage: generate a single Perlin noise value with pnoise2.

from noise import pnoise2 # Generate 2D Perlin noise value at (0.5, 0.5) with octaves=6 value = pnoise2(0.5, 0.5, octaves=6) print(value)

Debug

Known issues

breakingPython 2 only: the noise library on PyPI is Python 2 only. Install 'noise' on Python 3 may fail or produce incorrect results.

fix

Use the fork 'noise' (pip install noise) which supports Python 3, or use 'perlin-noise' package.

affects: 1.2.2

deprecatedProject unmaintained since 2015. No new features or bug fixes.

fix

Consider alternatives like 'noise' (fork), 'perlin-noise', or 'numpy' based implementations.

affects: all

gotchapnoise2 and pnoise3 return values in range approximately [-1, 1], but not clamped exactly. Use clamping if you need strict [0,1].

fix

Normalize: (value + 1) / 2.0

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'noise'

Python 3 environment - the original noise package is Python 2 only.

fix

Install the Python 3 compatible fork: pip install noise

ImportError: No module named noise

Package not installed or installed in wrong environment.

fix

Verify installation with: pip list | grep noise

TypeError: pnoise2() got an unexpected keyword argument 'octaves'

Using an older version of noise (pre-1.1.0) that does not support octaves parameter.

fix

Upgrade to latest version: pip install --upgrade noise
