问题描述
所以我在js中使用ml5在一个简单的NeuralNetwork上工作，它将使用P5 js库通过图像进行训练，将图像放入一个数组中，然后通过ml5训练它们，但我遇到了一个主要问题，我花了几个小时寻找这个错误的答案，但在任何地方都找不到它。 使用库p5、p5、sketch、ml5
JS档案
let RustImage = [];
function preload() {
for (let i = 0; i < 5; i++) {
RustImage[i] = loadImage(`RustPhotos/2020-12-08 (${i+7}).png`);
}
}
let NodeClassifier;
function setup() {
createCanvas(440, 440);
// background(0);
// image(RustImage[0], 0, 0, width, height);
let options = {
inputs: [128, 128, 4],
task: "imageClassification",
debug: true,
};
NodeClassifier = ml5.neuralNetwork(options);
for (let i = 0; i < RustImage.length; i++) {
NodeClassifier.addData({ image: RustImage[i] }, { label: "SulfurNode" });
}
NodeClassifier.normalizeData();
NodeClassifier.train({ epochs: 5 }, finishedTraining);
}
function finishedTraining() {
console.log("Finished Training!");
}

推荐答案
不确定它们是否相同，但在我的情况下，某些训练数据集只有1个输出标签的单一结果，因此模型不会训练。
它似乎与"；深度必须为>；=2有某种匹配，但它是1条消息(&q；)。
为确保我只需在数据集中手动添加另一个结果并重新启动
这篇关于One热中出错：深度必须为>；=2，但它是1的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
