ValueError: Error when checking input: expected input_1 to have 2 dimensions, but got array with shape (100, 100, 100, 3)
  • 原因
    输入第一层的张量与数据集的shape不同
  • 解决
    将data转置:
    data = data.reshape(len(data),-1)
    然后会报错:
ValueError: Error when checking input: expected input_1 to have shape (784,) but got array with shape (300,)

再把shape按照提示改正:
inputs = Input(shape=(300,))
