Tensorflow Tflearn键错误[]不在索引中

我有这段代码，我想我在神经网络中的数据去输入方面出了点问题（神经网络只是暂时的）

这是我的密码：

import pandas as pd
import numpy as np
from sklearn.model_selection import train_test_split
from sklearn import preprocessing

import tflearn

data = pd.read_csv('winequality-white.csv', sep=';')

X = data[['fixed acidity',
         'volatile acidity',
         'citric acid',
         'residual sugar',
         'chlorides',
         'free sulfur dioxide',
         'total sulfur dioxide',
         'density',
         'pH',
         'sulphates',
         'alcohol']]
y = data['quality']

X_train,X_test,y_train,y_test = train_test_split(X,y,test_size=0.1)


# Build neural network
net = tflearn.input_data(shape=[None, 11])
net = tflearn.fully_connected(net, 110)

net = tflearn.regression(net)

# Define model
model = tflearn.DNN(net)
# Start training (apply gradient descent algorithm)
model.fit(X_train, y_train, n_epoch=10, batch_size=1, show_metric=True)

我使用的数据如下所示：

"fixed acidity";"volatile acidity";"citric acid";"residual sugar";"chlorides";"free sulfur dioxide";"total sulfur dioxide";"density";"pH";"sulphates";"alcohol";"quality"
7;0.27;0.36;20.7;0.045;45;170;1.001;3;0.45;8.8;6

6.2;0.32;0.16;7;0.045;30;136;0.9949;3.18;0.47;9.6;6
...

这是我得到的错误：

有人提示出了什么问题吗？

将以下代码放在代码开头以重置图形。如果在IPython环境中以交互方式运行代码，tensorflow图可能会变得非常混乱

import tensorflow as tf
tf.reset_default_graph()
