快速，简单地从Dropbox导入:

!pip install dropbox
import dropbox
access_token = 'YOUR_ACCESS_TOKEN_HERE' # https://www.dropbox.com/developers/apps
dbx = dropbox.Dropbox(access_token)

# response = dbx.files_list_folder("")

metadata, res = dbx.files_download('/dataframe.pickle2')

with open('dataframe.pickle2', "wb") as f:
  f.write(res.content)

简单的方法从你的googledrive导入数据-这样做节省了人们的时间(不知道为什么谷歌只是没有明确地列出这一步)。

安装并验证pydrive

     !pip install -U -q PyDrive ## you will have install for every colab session

     from pydrive.auth import GoogleAuth
     from pydrive.drive import GoogleDrive
     from google.colab import auth
     from oauth2client.client import GoogleCredentials

     # 1. Authenticate and create the PyDrive client.
     auth.authenticate_user()
     gauth = GoogleAuth()
     gauth.credentials = GoogleCredentials.get_application_default()
     drive = GoogleDrive(gauth)

上传

如果您需要从本地驱动器上传数据:

    from google.colab import files

    uploaded = files.upload()

    for fn in uploaded.keys():
       print('User uploaded file "{name}" with length {length} bytes'.format(name=fn, length=len(uploaded[fn])))

执行，这将显示一个选择文件按钮-找到你的上传文件-点击打开

上传完成后，会显示:

    sample_file.json(text/plain) - 11733 bytes, last modified: x/xx/2018 - %100 done
    User uploaded file "sample_file.json" with length 11733 bytes

为笔记本创建文件

如果您的数据文件已经在您的gdrive中，您可以跳过这一步。

现在它在你的谷歌硬盘里。在谷歌驱动器中找到该文件，然后右键单击。点击获取“可共享链接”。你会得到一个窗口，上面有:

    https://drive.google.com/open?id=29PGh8XCts3mlMP6zRphvnIcbv27boawn

Copy - ' 29pgh8xcts3mlmp6zrphvnicbv27bown ' -这是文件ID。

在你的笔记本上:

    json_import = drive.CreateFile({'id':'29PGh8XCts3mlMP6zRphvnIcbv27boawn'})

    json_import.GetContentFile('sample.json') - 'sample.json' is the file name that will be accessible in the notebook.

将数据导入笔记本

导入你上传到笔记本的数据(在这个例子中是一个json文件-你如何加载取决于文件/数据类型- .txt，.csv等):

    sample_uploaded_data = json.load(open('sample.json'))

现在你可以打印数据:

    print(sample_uploaded_data)

一个演示本地文件上传/下载以及与Drive和sheets集成的官方示例笔记本可在这里获得: https://colab.research.google.com/notebooks/io.ipynb

共享文件最简单的方法是挂载您的谷歌驱动器。

要做到这一点，在代码单元格中运行以下命令:

from google.colab import drive
drive.mount('/content/drive')

它会要求您访问一个链接，以允许“谷歌文件流”访问您的驱动器。之后，一个长长的字母数字认证代码将显示，需要输入在你的Colab的笔记本。

之后，您的驱动器文件将被挂载，您可以在侧面板中的文件浏览器浏览它们。

这是一个完整的笔记本示例

从谷歌。Colab导入驱动器

驱动器(' /内容/ drive’山)

进口熊猫作为pd dv = pd.read_csv(' /内容/传动/ MyDrive /戴安娜/卡索/ Data_Caso_Propuesto.csv”) dv.info ()

from google.colab import files
import zipfile, io, os

    def read_dir_file(case_f):
        # author: yasser mustafa, 21 March 2018  
        # case_f = 0 for uploading one File and case_f = 1 for uploading one Zipped Directory
        uploaded = files.upload()    # to upload a Full Directory, please Zip it first (use WinZip)
        for fn in uploaded.keys():
            name = fn  #.encode('utf-8')
            #print('\nfile after encode', name)
            #name = io.BytesIO(uploaded[name])
        if case_f == 0:    # case of uploading 'One File only'
            print('\n file name: ', name)
            return name
        else:   # case of uploading a directory and its subdirectories and files
            zfile = zipfile.ZipFile(name, 'r')   # unzip the directory 
            zfile.extractall()
            for d in zfile.namelist():   # d = directory
                print('\n main directory name: ', d)
                return d
    print('Done!')

您可以通过运行以下命令挂载到谷歌驱动器 从谷歌。Colab导入驱动器 drive.mount(/内容/驱动器) 训练后复制数据从gdrive到colab根文件夹。

cp -r '/content/drive/My drive/ Project_data' '/content'

其中第一个路径是gdrive路径，第二个是colab根文件夹。

这种方法对于大数据的训练速度更快。
