> @Jane1702 @RobertoDonPedro @faiconda are you using the default model? Yes , I used the default model

Excuse-me , when I changed the code as you said , it finished the code but it didn't return the answer 

I have just run it successfully. I ran again with command prompt and it worked . Thank you very much for your help ^^ However , I don't know why...

 I don't know why but today I tried again and it worked normally . But it takes so long to have 1 answer (more than 20mins)
