调用预测函数时浏览器中的 Tensorflow.js 错误
我正在使用 Node.js 来运行 web 应用程序。这是我包含的脚本，我正在 Chrome 中运行 Node.js，但无法解决该错误。
该项目有 7 个类作为输出，是形状为 1x7 的输出的密集层。

这是我的 JavaScript 文件。
$(document).on('change', '#file', function() {
let reader = new FileReader();
reader.onload= function(){
let dataUrl = reader.result;
$('#selected-image').attr('src',dataUrl);
$('#type1-predict').empty();
$('#type2-predict').empty();
$('#type3-predict').empty();
$('#type4-predict').empty();
$('#type5-predict').empty();
$('#type6-predict').empty();
$('#type7-predict').empty();
}
let file = $('#file').prop('files')[0];
reader.readAsDataURL(file)
});
const CANCER_CLASSES = {
0:"Actinic Keratoses",
1:"Basal cell carcinoma",
2:"Benign keratosis",
3:"Dermatofibroma",
4:"Melanoma",
5:"Melanocytic nevi",
6:"Vascular skin",
}
let model;
(async function(){
model= await tf.loadLayersModel('http://localhost:81/model/model.json');
$('#pro').hide()
})();
$(document).on('click', '#predict-button', async function() {
let image = $('#selected-image').get(0);
let tensor =
tf.browser.fromPixels(image)
.resizeNearestNeighbor([224,224])
.toFloat()
.expandDims();
let prediction = await model.predict(tensor).data();
let top3 = Array.from(prediction)
.map(function(p,i){
return {
probab: p,
classname:CANCER_CLASSES[i]
};
}).sort(function(a,b){
return b.probab-a.probab;
}).slice(0,4);
$("#type1-predict").empty();
top3.forEach(function(p){
$('#type1-predict').append(`<li>${p.classname}:
${p.probab.tpFixed(6)}
</li>`);
});
});
这是 HTML 文件的一个片段

您能帮我解决以下错误吗：
