MemoryError-如何使用Python通过Google Drive SDK下载大文件

Question

当我从谷歌驱动器下载大文件时，内存快用完了。我假设tmp=content.read(1024)不起作用，但是如何修复它呢？谢谢你。

def download_file(service, file_id):
  drive_file = service.files().get(fileId=file_id).execute()
  download_url = drive_file.get('downloadUrl')
  title = drive_file.get('title')
  originalFilename = drive_file.get('originalFilename')
  if download_url:
    resp, content = service._http.request(download_url)
    if resp.status == 200:
      file = 'tmp.mp4'
      with open(file, 'wb') as f:
          while True:
              tmp = content.read(1024)
              if not tmp:
                  break
              f.write(tmp)
      return title, file
    else:
      print 'An error occurred: %s' % resp
      return None
  else:
    return None
