我正在尝试在 python 中执行以下操作:
from pandas import *
tickdata = read_csv('/home/user/sourcefile.csv',index_col=0,parse_dates='TRUE')
csv 文件的行如下所示:
2011/11/23 23:56:00.554389,1165.2500
2011/11/23 23:56:02.310943,1165.5000
2011/11/23 23:56:05.564009,1165.2500
在 pandas .7 上,这执行得很好。在 pandas .8.0rc2 上,我收到以下错误。因为我在两个不同的系统上安装了 .7 和 .8,所以我没有排除依赖关系或 python 版本差异。任何关于如何让它在 0.8 下执行的想法都值得赞赏。
