PyCharm使用过程中的问题记录

1. 'c'  engine does not support regex separators:

解决：在报错的代码后面加上engine=‘python’

rating = pd.read_table('C:\\Users\\aiMayday\\PycharmProjects\\untitled\\ml-1m\\ratings.dat', sep='::', header=None, names=rnames, engine='python')

3.报错： StandardScaler.fit_transform(iris.data)
TypeError: unbound method fit_transform() must be called with StandardScaler instance as first argument (got ndarray instance instead)

解决：
    StandardScaler().fit_transform(iris.data)
