下面是错误提示

csv.writer(open(train_csv, 'w+'), lineterminator='\n').writerows([header[:-1]] + trn)
IOError: [Errno 13] Permission denied: '/media/johnsnow/train.csv'
出错那一行的源代码：csv.writer(open(train_csv,'w+'),lineterminator='\n').writerows([header[:-1]]) +trn)
train.csv 与 train_csv 检查文件路径是否对，直接把这行代码拿出来测试。 如果以上都对，还报错，可能是编码错误比如，你的train.csv 是unicode编码，你读的时候用的utf 编码，第一种方法，打开用Excel 进行另存为，改编码，第二种方法wb+
提示很明显，没有权限。给目录和文件权限。
没有权限。给目录和文件权限。 chmod 777 train_csv
