通过Keras减少张量尺寸

标签： keras tensor

我发现我的模型有一个形状为 public getALL(){ this.woo.fetchItems('products') .then(products => { for(var i = 0; i < products.length; i++) { this.products.push(products[i]) } }) .catch(error => console.log(error)); } 的张量。我想知道如何将其减少到(?,1,60)？不确定是否可以对尺寸进行重塑或展平。有什么帮助吗？

两个图层都可以使用，但在这种情况下，我更喜欢使用keras.layers.Flatten。这是一个例子：
