分离数据集老是出现错误

Question

from pandas import read_csv

dataset=read_csv(r'C:\Users\Administrator\Desktop\ARI.csv', names=names)
print(dataset.describe())
dataset.hist(sharex=False,sharey=False,Xlabelsize=1,Ylabelsize=1)
pyplot.show()
print(dataset.groupby('ARISe').size())
scatter_matrix(dataset)
pyplot.show()
#分离数据集
array=dataset.values
X=array[:,0:17]
Y=array[:, 17]
test_size=0.2
seed=7
X_train, X_test, Y_train, Y_test=
train_test_split(X, Y, test_size=test_size,random_state=seed)

报错：AttributeError: 'Rectangle' object has no property 'xlabelsize'
为什么呢

Answer 1

报错应该是在 dataset.hist那条语句，其中参数名写错了，两个参数分别是 xlabelsize和 ylabelsize，x,y不要写成大写的，改成如下：

dataset.hist(sharex=False,sharey=False,xlabelsize=1,ylabelsize=1)

如有帮助，请点采纳。
