ValueError: Failed to find data adapter that can handle input

Hello,
While trying to train the neurall network for In-hospital mortality prediction this Error occurs:

==> training
Traceback (most recent call last):

    raise ValueError(
ValueError: Failed to find data adapter that can handle input: <class 'numpy.ndarray'>, (<class 'list'> containing values of types {"<class 'int'>"})

I've tried to convert x and y to np array, but still get this error

x=train_raw[0];
 y=train_raw[1];
 x = np.array(x)
 y = np.array(y)

Did anyone had this error as well and found a solution or any ideas what could solve the problem?

Thanks in advance!

The val_raw needs to be converted to NumPy array as well.

I added
train_raw = (np.array(train_raw[0]), np.array(train_raw[1])) and
val_raw = (np.array(val_raw[0]), np.array(val_raw[1])).
Then it works for me.
