Huey, Flask :ModuleNotFoundError: No module named 'run_huey'

Question

I'm trying to use python huey (https://github.com/coleifer/huey/blob/master/huey/api.py) to allow usage of a task queue with flask.

Starting with the file app.tasking.tasks:

from . import my_huey
from app.main.cl import dummy_create_cl_listing, create_cl_listing
from app.main.mobiletest import some_long_calculation,create_chromedriver

create_cl_listing_task = my_huey.task()(create_cl_listing)
some_long_calculation_task = my_huey.task()(some_long_calculation)
@my_huey.task()
def dummy_create_task(messages):
    time.sleep(5)
    print('continuing..')
    time.sleep(25)
    return 'fin'

If I run :

$ python ...huey_consumer.exe run_huey.huey where run_huey.py (which is a file in the project root directory) contains:

from app.tasking.tasks import my_huey as huey
if __name__ == '__main__':
    pass

I see:

[2018-08-22 14:10:58,587] INFO:huey.consumer:MainThread:The following commands are available:
+ queue_task_create_cl_listing
+ queue_task_some_long_calculation
+ queue_task_dummy_create_task

showing that the tasks are available. However, if I am unable to import the functions which I have turned into tasks into the app.main.views file so that I can call it via a view function. for example if I add:

from app.tasking.tasks import some_long_calculation_task 

to the main.views file:

During handling of the above exception, another exception occurred:

  File "...\app\main\views.py", line 14, in <module>
    from app.tasking.tasks import some_long_calculation_task
ImportError: cannot import name 'some_long_calculation_task'

How can I fix this?
