在训练和测试数据集中拆分后，在tf.stack中获得Keyerror 0

如何解决在训练和测试数据集中拆分后，在tf.stack中获得Keyerror 0

将数据集分为训练和测试数据集后，在tf.stack中得到了关键错误0。如果我将所有数据放入堆栈，则一切正常。 X_train也可以。 X_test显示关键错误0。我已经减少了数据并手动检查->没有单元格为空。

Text_3dtensor_all = tf.stack(Tweets_final.Text_Vector,axis=0)

X_train,X_test,y_train,y_test = train_test_split(Tweets_final.Text_Vector,Tweets_final.Senti,test_size=0.2)

Text_3dtensor_xtrain = tf.stack(X_train,axis=0)

Text_3dtensor_xtest = tf.stack(X_test,axis=0)

输出控制台

    Text_3dtensor_xtest = tf.stack(X_test,axis=0)
Traceback (most recent call last):
