node.js - face-api.js 从磁盘加载图像文件

Question

我尝试使用face-api.js从磁盘加载图像:

faceapi.fetchImage(path.resolve(INPUT_DIR, 'input1.jpg');

它抛出以下错误:错误:fetch - 缺少 Nodejs 环境的 fetch 实现


还有其他方法可以从磁盘加载图像并使用nodejs显示吗？

documentation建议您使用canvas做这样的事情:

const canvas = require('canvas');
faceapi.env.monkeyPatch({ Canvas, Image })
const img = await canvas.loadImage('./img.jpg');
const detections = await faceapi.detectSingleFace(img);

fetchImage will not work with local files :

faceapi.fetchImage as the name implies uses fetch under the hood, thus it doesn't work with filepaths to local files.
