Pandas read the CSV file hint does not exist for what reason?

The general case is that the data file is not in the current path, so it cannot read the data. Also, if the path name contains Chinese it is unreadable.

(1) You can choose:

Import OS

OS.GETCWD ()

Get the current working path, put your data file on this path, you can directly use Pd.read_csv ("./_.csv")

(2) You can choose:

Using Os.chdir (path), path is your data file

(3) You can choose:

Without changing the path, directly call the Df=pd.read_csv (U "file storage disk (e.g. C-drive):/folder/file name. CSV "), such as the stock data of the Python folder in the C drive: da = pd.read_csv (U" C:/python2.7/stock data/sh600.csv ")

If it is available under Ubuntu system: Data = Pd.read_csv (U "/home/lilai/tinic/train")
