我试图将文件从我的google驱动器下载到colaboratory。

file_id = '1uBtlaggVyWshwcyP6kEI-y_W3P8D26sz'

import io
from googleapiclient.http import MediaIoBaseDownload

request = drive_service.files().get_media(fileId=file_id)
downloaded = io.BytesIO()
downloader = MediaIoBaseDownload(downloaded, request)
done = False
while done is False:
  # _ is a placeholder for a progress object that we ignore.
  # (Our file is small, so we skip reporting progress.)
  _, done = downloader.next_chunk()

downloaded.seek(0)
print('Downloaded file contents are: {}'.format(downloaded.read()))

这样做会收到此错误:

NameError: name 'drive_service' is not defined

如何删除此错误?

不安装/导入任何库。只需将文件ID放在末尾即可。

!gdown --id yourFileIdHere

注意:在编写本文时,colab上已预安装gdown库。

将文件从Google驱动器下载到colabo笔记本的最简单方法是通过colabo api:

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

!cp '/content/gdrive/My Drive/<file_path_on_google_drive>' <filename_in_colabo>

备注:

  1. 通过drive.mount(),您可以访问Google驱动器上的任何文件。
  2. “我的云端硬盘”等同于本地文件系统上的“ Google云端硬盘”。
  3. file_path用单引号引起来,因为安装点(“我的驱动器”)下方的标准目录中有一个空格,而且无论如何,您的路径中也可能有空格。
  4. 文件浏览器(通过单击左箭头激活)对于查找文件和获取文件路径非常有用。它使您可以单击已安装的文件夹结构并复制文件路径,请参见下图。

您需要定义驱动器API服务客户端以与Google驱动器API进行交互,例如:

from googleapiclient.discovery import build
drive_service = build('drive', 'v3')

(参见笔记本External data: Drive, Sheets, and Cloud Storage/Drive REST API

我建议您使用Pydrive从谷歌硬盘下载文件。我下载500MB数据集5s。 1.安装Pydrive

!pip install PyDrive

2。 OAouth

from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

gauth = GoogleAuth()
gauth.LocalWebserverAuth()

drive = GoogleDrive(gauth)

3。谷歌驱动器下载文件的代码

fileId = drive.CreateFile({'id': 'DRIVE_FILE_ID'}) #DRIVE_FILE_ID is file id example: 1iytA1n2z4go3uVCwE_vIKouTKyIDjEq
print fileId['title']  # UMNIST.zip
fileId.GetContentFile('UMNIST.zip')  # Save Drive file as a local file

第1步

!pip install -U -q PyDrive

第2步

from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth
from oauth2client.client import GoogleCredentials
# Authenticate and create the PyDrive client.
# This only needs to be done once per notebook.
auth.authenticate_user()
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)

Step3

file_id = '17Cp4ZxCYGzWNypZo1WPiIz20x06xgPAt' # URL id. 
downloaded = drive.CreateFile({'id': file_id})
downloaded.GetContentFile('shaurya.txt')

Step4

!ls #to verify content

OR

import os
print(os.listdir())

这是一种轻松的解决方法。您可以在Python中使用wget命令或请求模块来完成工作。

# find the share link of the file/folder on Google Drive
file_share_link = "https://drive.google.com/open?id=0B_URf9ZWjAW7SC11Xzc4R2d0N2c"

# extract the ID of the file
file_id = file_share_link[file_share_link.find("=") + 1:]

# append the id to this REST command
file_download_link = "https://docs.google.com/uc?export=download&id=" + file_id 

可以将file_download_link中的字符串粘贴到浏览器地址栏中,以直接获取下载对话框。

如果使用wget命令:

!wget -O ebook.pdf --no-check-certificate "$file_download_link"

您还可以在https://github.com/ruelj2/Google_drive的google.colab和PyDrive上使用我的实现,这使它变得容易得多。

!pip install - U - q PyDrive  
import os  
os.chdir('/content/')  
!git clone https://github.com/ruelj2/Google_drive.git  

from Google_drive.handle import Google_drive  
Gd = Google_drive()  
Gd.load_file(local_dir, file_ID)
