Question

need some help Can't start using dramatiq because some errors

My structure is

projectDirectory/apptest/
  __init__.py  (Eempty file. Not really empty, all lines commented with #)
  test.py 

I'm using Conda environment with dramatiq installed via pip

#--- test.py has the following code

import dramatiq

@dramatiq.actor
def lenstring(txt):
  print(len(txt))

if __name__ == "__main__":
  lenstring.send("hello")

Problem is... 1- Loading environment using conda activate 2- Running dramatiq from apptest in order to start worker

I don't understad how to solve the problem, can someone help me?

I try to start a dramatiq worker, the code is just a simplyfied variation of some example I found on the web. I have a much more complex code to run but can't event start with this simple one (The errors on the complex code is basically the same)

Answer 1

When using the dramatiq command, you shouldn't use the ".py" file extension. Type it out like you would if you were importing something.

In your case it would be: dramatiq test
