I am using this command to run celery task on my windows 7 pc:

celery -A sentiment_worker_test worker -l info -P eventlet

it all displays and connected successfully...

but when i run this sentiment_worker_test.py file in another terminal with command:"python sentiment_worker_test.py" then it shows "None" in result...

and at the celery command prompt window it shows following response..

[2018-10-31 11:19:13,104: INFO/MainProcess] celery@dell-PC ready. [2018-10-31 11:19:13,105: INFO/MainProcess] Received task: sentiment_worker_test .classify_demo[4d173818-64f6-400a-a75b-344074921461] [2018-10-31 11:19:13,107: WARNING/MainProcess] There is some error, please retry with different input [2018-10-31 11:19:13,108: INFO/MainProcess] pidbox: Connected toamqp://guest:**@127.0.0.1:5672//.

I dont know what that warning means..."There is some error, please retry with different input".. i have tried almost all different types of inputs... but none worked...

any help would be appreciated

Thanks in advance
