这是代码的一部分：

n_epochs=5
for epoch in range(n_epochs):
    loss=0.    
    for i,doc in enumerate(X_train_tokens):
        data,labels=skipgrams(sequence=doc,vocabulary_size=vocab_size,window_size=4)
        x=[np.array(x) for x in zip(*data)]
        y=np.array(labels,dtype=np.int32)
        if x:
            loss +=model.train_on_batch(x,y)
    print('Epoch:',epoch,'\t loss:',loss)

出现以下错误

从内存中删除基础状态对象，否则它将保留 活着，因为从追溯中可以引用状态 由于InvalidArgumentError：indexs [7,0] = 3795不在[0，3795）
