我正在尝试使用Pandas读取电影数据集：http://files.grouplens.org/datasets/movielens/ml-100k/。我使用的是Python 3.4版本，并且遵循这里的教程。
当我尝试使用那里提到的代码读取u.item数据时：
当我尝试使用那里提到的代码读取u.item数据时：
# the movies file contains columns indicating the movie's genres
# let's only load the first five columns of the file with usecols
m_cols = ['movie_id', 'title', 'release_date', 'video_release_date', 'imdb_url']
movies = pd.read_csv('ml-100k/u.item', sep='|', names=m_cols, usecols=range(5), encoding='UTF-8')
我得到了以下错误信息："UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe9 in position 3: invalid continuation byte"。
这个错误的可能原因是什么，有什么解决办法呢？
我尝试在pd.read_csv( encoding='utf-8' )中添加encoding='utf-8'，但不幸的是它没有解决任何问题。
错误追踪如下：
