如何使用pydrive将文件夹上载到google drive？到目前为止，我已经完成上传文件。感谢您的帮助，谢谢

Question

f = drive.CreateFile({"parents": [{"kind": "linktodrive", "id": fid}]})
f.SetContentFile('traffic_measurement'+str(y)+'.csv')

f1 = drive.CreateFile({"parents": [{"kind": "linktodrive", "id": fid}]})
f1.SetContentFile('speed_violation'+str(y)+'.csv')

f2 = drive.CreateFile({"parents": [{"kind": "linktodrive", "id": fid}]})
f2.SetContentFile('detected_vehicles'+str(y))

f3 = drive.CreateFile({"parents": [{"kind": "linktodrive", "id": fid}]})
f3.SetContentFile('speed_violation'+str(y))

f.Upload()
f1.Upload()
f2.Upload()
f3.Upload()

文件已成功上载，然后我尝试上载文件夹，显示以下错误。你知道吗

self.content = open(filename, 'rb')
PermissionError: [Errno 13] Permission denied: 'detected_vehicles2019-10-18
