javascript - 如何保存 Tensorflow.js 模型?
我想制作一个能够创建、保存和训练 tensorflow.js 模型的用户界面。但我在创建模型后无法保存它。我甚至从 tensorflow.js 文档中复制了这段代码,但它不起作用:
const model = tf.sequential(
{layers: [tf.layers.dense({units: 1, inputShape: [3]})]});
console.log('Prediction from original model:');
model.predict(tf.ones([1, 3])).print();
const saveResults = await model.save('localstorage://my-model-1');
const loadedModel = await tf.loadModel('localstorage://my-model-1');
console.log('Prediction from loaded model:');
loadedModel.predict(tf.ones([1, 3])).print();我总是收到错误信息“Uncaught SyntaxError: await 仅在异步函数中有效”。我该如何修复这个问题?谢谢!
答案#1
你需要在异步环境中。要么创建一个异步函数(async function name(){...})并在需要时调用,要么最简短的方法是使用自调用异步箭头函数:
(async ()=>{
//you can use await in here
})()
答案#2
创建一个异步函数并调用它:
async function main() {
const model = tf.sequential({
layers: [tf.layers.dense({ units: 1, inputShape: [3] })]
});
console.log("Prediction from original model:");
model.predict(tf.ones([1, 3])).print();
const saveResults = await model.save("localstorage://my-model-1");
const loadedModel = await tf.loadModel("localstorage://my-model-1");
console.log("Prediction from loaded model:");
loadedModel.predict(tf.ones([1, 3])).print();
}
main();
