我是ML的初学者，在拟合模型时，我很难将numpy数组转换为Tensor。
当我尝试时得到的错误

test_audio_class(x_train.values, y_train.values, x_test.values, y_test.values)

字符串
为

Traceback (most recent call last):
  File "classifier.py", line 51, in <module>
    test_audio_class(x_train.values, y_train.values, x_test.values, y_test.values)
  File "classifier.py", line 28, in test_audio_class
    history = model.fit(x_train, y_train, epochs = 10, validation_data = (x_test, y_test))

line 102, in convert_to_eager_tensor
    return ops.EagerTensor(value, ctx.device_name, dtype)
ValueError: Failed to convert a NumPy array to a Tensor (Unsupported object type tensorflow.python.framework.ops.EagerTensor).

我尝试了一些print语句来找出错误。

type of x_train = <class 'numpy.ndarray'>, values in x_train = <class 'tensorflow.python.framework.ops.EagerTensor'>
type of y_train = <class 'numpy.ndarray'>, values in y_train = <class 'str'>

我知道这与我正在做的EagerTensor有关，但不知道如何修复它。
