drive.mount('/content/gdrive/')

我很懒，我的记忆力很差，所以我决定创建一个更容易记忆和输入的easycolab:

import easycolab as ec
ec.mount()

确保首先安装它:!pip install easycolab

mount()方法基本上实现了这一点:

from google.colab import drive
drive.mount(‘/content/drive’)
cd ‘/content/gdrive/My Drive/’

我写了一个类来下载所有的数据到。’在colab服务器中的位置

整个事情可以从这里拉https://github.com/brianmanderson/Copy-Shared-Google-to-Colab

!pip install PyDrive


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

class download_data_from_folder(object):
    def __init__(self,path):
        path_id = path[path.find('id=')+3:]
        self.file_list = self.get_files_in_location(path_id)
        self.unwrap_data(self.file_list)
    def get_files_in_location(self,folder_id):
        file_list = drive.ListFile({'q': "'{}' in parents and trashed=false".format(folder_id)}).GetList()
        return file_list
    def unwrap_data(self,file_list,directory='.'):
        for i, file in enumerate(file_list):
            print(str((i + 1) / len(file_list) * 100) + '% done copying')
            if file['mimeType'].find('folder') != -1:
                if not os.path.exists(os.path.join(directory, file['title'])):
                    os.makedirs(os.path.join(directory, file['title']))
                print('Copying folder ' + os.path.join(directory, file['title']))
                self.unwrap_data(self.get_files_in_location(file['id']), os.path.join(directory, file['title']))
            else:
                if not os.path.exists(os.path.join(directory, file['title'])):
                    downloaded = drive.CreateFile({'id': file['id']})
                    downloaded.GetContentFile(os.path.join(directory, file['title']))
        return None
data_path = 'shared_path_location'
download_data_from_folder(data_path)

从谷歌colab笔记本中提取谷歌Drive zip，例如:

import zipfile
from google.colab import drive

drive.mount('/content/drive/')

zip_ref = zipfile.ZipFile("/content/drive/My Drive/ML/DataSet.zip", 'r')
zip_ref.extractall("/tmp")
zip_ref.close()

好消息，PyDrive对CoLab有一流的支持!PyDrive是谷歌Drive python客户端的包装器。下面是一个关于如何从一个文件夹下载所有文件的例子，类似于使用glob + *:

!pip install -U -q PyDrive
import os
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)

# choose a local (colab) directory to store the data.
local_download_path = os.path.expanduser('~/data')
try:
  os.makedirs(local_download_path)
except: pass

# 2. Auto-iterate using the query syntax
#    https://developers.google.com/drive/v2/web/search-parameters
file_list = drive.ListFile(
    {'q': "'1SooKSw8M4ACbznKjnNrYvJ5wxuqJ-YCk' in parents"}).GetList()

for f in file_list:
  # 3. Create & download by id.
  print('title: %s, id: %s' % (f['title'], f['id']))
  fname = os.path.join(local_download_path, f['title'])
  print('downloading to {}'.format(fname))
  f_ = drive.CreateFile({'id': f['id']})
  f_.GetContentFile(fname)


with open(fname, 'r') as f:
  print(f.read())

注意驱动的参数。ListFile是一个字典，它与谷歌Drive HTTP API使用的参数相一致(您可以自定义q参数，以调优您的用例)。

要知道，在所有情况下，文件/文件夹都是通过谷歌驱动器上的id进行编码的(参见1SooKSw8M4ACbznKjnNrYvJ5wxuqJ-YCk)。这要求您在谷歌驱动器中搜索与您想要在其中查找的文件夹对应的特定id。

例如，导航到“/projects/my_project/my_data”文件夹 位于您的谷歌驱动器。

它包含一些文件，我们希望将这些文件下载到CoLab。要获得文件夹的id以便PyDrive使用它，请查看url并提取id参数。在本例中，文件夹对应的url为:

其中id是url的最后一部分:1SooKSw8M4ACbznKjnNrYvJ5wxuqJ-YCk。
