Kaggle-ValueError: Input contains NaN, infinity or a value too large for dtype('float32').

在按照教程一步一步做的时候，出现如下错误：

ValueError: Input
contains NaN, infinity
or a value too large for dtype('float32').

Just for the record, I had the same error message and found that it was caused by NaN's. I imputed them as follows:

from sklearn.preprocessing import Imputer

trainDataVecs = Imputer().fit_transform(trainDataVecs)

如此即可。
