我的数据格式Tensor[(shape=[3, 224, 224], dtype=float64, place=CPUPlace, stop_gradient=True)，label]，继承了iodataset的类，

但是报错为

(InvalidArgument) input and filter data type should be consistent, but received input data type is double and filter type is float
[Hint: Expected input_data_type == filter_data_type, but received input_data_type:6 != filter_data_type:5.] (at /paddle/paddle/fluid/operators/conv_op.cc:211)
[operator < conv2d > error]

老师们，到底怎么解决这个问题
