索引=2不在[0,1]中

嗨,我正在做SEQ2SQL项目,我成功地建立了一个模型,但当培训时,我得到以下错误,我也没有使用任何keras嵌入层。下面是我的代码

M=13 #Question Length
d=40 #Dimention of the LSTM
C=12 #number of table Columns 

batch_size=9
inputs1=Input(shape=(M,100),name='question_token')
Hq=Bidirectional(LSTM(d,return_sequences=True),name='QuestionENC')(inputs1) #this is HQ shape is (num_samples,13,80)

def hidd(te):
    t=tf.Variable(initial_value=1,dtype=tf.int32)

    for i in range(batch_size):  
        t=tf.assign(t,i)
        Z = tf.nn.embedding_lookup(te, t)
        print(col_lstm_layer(Z))
        h=tf.reshape(col_lstm_layer(Z),[1,C,d*2])
        if i==0:
#             cols_last_hidden=tf.Variable(initial_value=h)
            cols_last_hidden=tf.stack(h)#this is because it gives an error if we use tf.Variable here
        else:
            cols_last_hidden=tf.concat([cols_last_hidden,h],0)#shape of this one is (num_samples,num_col,80) 80 is last encoding of each column
    return cols_last_hidden

                all_col_attention=tf.stack(Ecol)

history=model.fit([Equestion,Col_Embeddings],y_train,epochs=50,validation_split=.1,shuffle=False,callbacks=[earlyStopping],batch_size=batch_size)

Equestion、Col_Embeddings和Y_Train的形状是(10、12、3、100)、(10、13、100)和(10、12)。我搜索了有关此错误的信息,但所有这些情况下,他们都错误地使用了嵌入层。但在这里,虽然我没有使用它,但我得到了这个错误
