我将 Keras 模型转换为 tfjs,并在浏览器中运行它时收到以下警告:
topology.ts:1114 输入张量的形状 ([null,1024]) 与 layer dense: [null,[224,224,3]] 的期望不匹配
模型摘要如下所示:
_________________________________________________________________

mobilenet_1.00_224 (Model) [null,1024] 3228864

Total params: 3626439
Trainable params: 397575
Non-trainable params: 3228864
对于预测,我实施了以下方法:
async function classifyImage() {
const cam = await tf.data.webcam(video); //video is a webcam element with 224x224 pixels
const img = await cam.capture();
console.log(img.shape);
let new_frame = img.reshape([1, 224, 224, 3]);
predictions = await model.predict(new_frame).print();
}
如何解决警告信息?
