fpsample

✓ import fpsample

No common wrong import; the package exposes a single module.

Sample a subset of points from a point cloud using farthest point sampling.

import numpy as np import fpsample # Generate random point cloud: N x D (e.g., N=1000, D=3) points = np.random.rand(1000, 3).astype(np.float32) # Sample 10 points using farthest point sampling indices = fpsample.fps_sampling(points, 10) print(indices)

Debug

Known issues

gotchaThe input point cloud must be a 2D numpy array of shape (N, D) with dtype float32. Other dtypes (e.g., float64) may cause errors or performance issues.

fix

Convert input to float32 with points.astype(np.float32).

affects: all

gotchaThe function fps_sampling returns 0-based indices. Do not assume 1-based indexing.

fix

Use the returned indices as 0-based array indices.

affects: all

deprecatedThe function fps_sample is deprecated and may be removed in a future release. Use fps_sampling instead.

fix

Replace fps_sample with fps_sampling.

affects: >=1.0.0

Errors

Common errors & fixes

TypeError: 'numpy.float64' object cannot be interpreted as an integer

Input array has dtype float64, which is not supported.

fix

Convert input to float32: points = points.astype(np.float32)

ValueError: points must be a 2D array

Input is not a 2D numpy array (e.g., 1D or 3D).

fix

Ensure point cloud is a 2D array of shape (N, D).
