在 Angular 上使用 tensorflow 时无法编译片段着色器
failed to compile fragment shader when using tensorflow on Angular
我正在尝试在 angular 应用程序上实施迁移学习。对于新数据的收集,我想我将只使用与 tensorflow js 教程中完全相同的代码,即在 pacman 游戏中使用的代码。
这是 tensorflow.js 教程中 controller_dataset.js 的代码。我在 angular.
上的一个组件上导入了它
import * as tf from '@tensorflow/tfjs';
export class ControllerDataset {
constructor(numClasses) {
this.numClasses = numClasses;
}
addExample(example, label) {
const y = tf.tidy(() => tf.oneHot(tf.tensor1d([label]).toInt(), this.numClasses));
if (this.xs == null) {
this.xs = tf.keep(example);
this.ys = tf.keep(y);
} else {
const oldX = this.xs;
this.xs = tf.keep(oldX.concat(example, 0));
const oldY = this.ys;
this.ys = tf.keep(oldY.concat(y, 0));
oldX.dispose();
oldY.dispose();
y.dispose();
}
}
}
问题是当调用 controller.addExample 时会导致以下错误

您的错误来自使用 this.numClasses
。在你的 class 的构造函数中,你传入了参数 numClasses
。但是当你的组件被调用时,没有定义参数 numClasses 。结果,this.numClasses
将是未定义的。
考虑为 this.numClasses
分配一个值
addExample(example, label) {
// set this.numClasses with a value
const y = tf.tidy(() => tf.oneHot(tf.tensor1d([label]).toInt(), this.numClasses));
}
