如何从google drive将数据导入google colab？

Question

我有一些数据文件上传到我的谷歌驱动器上。 我想把这些文件导入google colab。

REST API方法和PyDrive方法展示了如何创建一个新文件并将其上传到drive和colab上。使用它，我无法理解如何在python代码中读取驱动器上已经存在的数据文件。

我完全是个新手。有人能帮我吗？

Answer 1

（2018年4月15日更新：gspread经常更新，因此为了确保稳定的工作流，我指定了版本）

对于电子表格文件，基本思想是使用gspread和pandas包读取驱动器中的电子表格并将其转换为pandas数据帧格式。

在Colab笔记本中：

#install packages
!pip install gspread==2.1.1
!pip install gspread-dataframe==2.1.0
!pip install pandas==0.22.0


#import packages and authorize connection to Google account:
import pandas as pd
import gspread
from gspread_dataframe import get_as_dataframe, set_with_dataframe
from google.colab import auth
auth.authenticate_user()  # verify your account to read files which you have access to. Make sure you have permission to read the file!
from oauth2client.client import GoogleCredentials
gc = gspread.authorize(GoogleCredentials.get_application_default()) 

然后我知道三种阅读谷歌电子表格的方法。

按文件名：

spreadsheet = gc.open("goal.csv") # Open file using its name. Use this if the file is already anywhere in your drive
sheet =  spreadsheet.get_worksheet(0)  # 0 means the first sheet in the file
df2 = pd.DataFrame(sheet.get_all_records())
df2.head()

按url:

 spreadsheet = gc.open_by_url('https://docs.google.com/spreadsheets/d/1LCCzsUTqBEq5pemRNA9EGy62aaeIgye4XxwReYg1Pe4/edit#gid=509368585') # use this when you have the complete url (the edit#gid means permission)
    sheet =  spreadsheet.get_worksheet(0)  # 0 means the first sheet in the file
    df2 = pd.DataFrame(sheet.get_all_records())
    df2.head()

按文件密钥/ID：

spreadsheet = gc.open_by_key('1vpukIbGZfK1IhCLFalBI3JT3aobySanJysv0k5A4oMg') # use this when you have the key (the string in the url following spreadsheet/d/)
sheet =  spreadsheet.get_worksheet(0)  # 0 means the first sheet in the file
df2 = pd.DataFrame(sheet.get_all_records())
df2.head()

！）将您的数据设置为公开，然后 对于公共电子表格：

from StringIO import StringIO  # got moved to io in python3.

import requests
r = requests.get('https://docs.google.com/spreadsheet/ccc? 
key=0Ak1ecr7i0wotdGJmTURJRnZLYlV3M2daNTRubTdwTXc&output=csv')
data = r.content

In [10]: df = pd.read_csv(StringIO(data), index_col=0,parse_dates= 
['Quradate'])

In [11]: df.head()

如果私人数据有点相同，但你将不得不做一些授权体操。。。
