How to run pyleus on Storm
Question: I'm a learning on Storm, I have installed zookeeper, storm, python and pyleus.
the first step, I copy python script from pyleus web as a sample
(<https://github.com/Yelp/pyleus/tree/aaa423864f953332202832b8fd8404e03d3d74e3>
) and try to run it in storm server, the sample include below 3 files:
pyleus_topology.yaml, dummy_spout.py and dummy_bolt.py the 2 py file has been
put into a folder namely "my_first_topology" but when I run the pyleus build
command in my VMware server(CentOS64-bit), the command can run 20 second and
then, I got below error:

> _[root@localhost bin]# pyleus build /root/Desktop/CRM_ETL-Project-
> Storm/my_first_topology/pyleus_topology.yaml pyleus build: error:
> [VirtualenvError] Failed to execute Python module:
> my_first_topology.dummy_spout. Error:
> /tmp/tmpZMIXa3/resources/pyleus_venv/bin/python: No module named
> my_first_topology_

what I can do for it? any steps I missed?

the script for reference 1> pyleus_topology.yaml

name: my_first_topology

topology:

    
    
    - spout:
        name: my-first-spout
        module: my_first_topology.dummy_spout
    - bolt:
        name: my-first-bolt
        module: my_first_topology.dummy_bolt
        groupings:
            - shuffle_grouping: my-first-spout
    

2> dummy_spout.py

from pyleus.storm import Spout

class DummySpout(Spout):

    
    
    OUTPUT_FIELDS = ['sentence', 'name']
    def next_tuple(self):
        self.emit(("This is a sentence.", "spout",))
    

if **name** == '**main** ': DummySpout().run()

3> dummy_bolt.py

from pyleus.storm import SimpleBolt

class DummyBolt(SimpleBolt):

    
    
    OUTPUT_FIELDS = ['sentence']
    def process_tuple(self, tup):
        sentence, name = tup.values
        new_sentence = "{0} says, \"{1}\"".format(name, sentence)
        self.emit((new_sentence,), anchors=[tup])
    

if **name** == '**main** ': DummyBolt().run()


Answer: I think your problem is that you are missing an empty file named "__init.py__"
in your inner my_first_topology folder. That file makes it a python module.
Just create it and you should be set.
