错误:等级4的x的dot支持尚未实现

我使用Tensorflow.js来预测我在Keras中训练的模型。然而,当我输入我的四维张量时,我会得到以下错误:

UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: dot support for x of rank 4 is not yet implemented: x shape = 32,1,1,100

model.predict(noise_tensor) . 大多数代码都是不相关的:

  noise_tensor.print(true)

  generated_images = model.predict(noise_tensor) //error occours here

这是我的4d张量的打印输出:
