Cannot do relative imports from outside the topology folder

[aapostol87]

I am trying to create a generic bolt outside the topology directory.
This is because I wanna use a storage factory and this applies for all my bolts.

When I build it it trows an error.

Let me paste my trace:
pyleus build: error: [VirtualenvError] Failed to execute Python module: train_topology.normalize_data_bolt. Error: Traceback (most recent call last):
File "/usr/lib/python2.7/runpy.py", line 174, in _run_module_as_main
"main", fname, loader, pkg_name)
File "/usr/lib/python2.7/runpy.py", line 72, in _run_code
exec code in run_globals
File "/tmp/tmpnZDGeG/resources/train_topology/normalize_data_bolt.py", line 8, in
from src.tuples import Message
ImportError: No module named src.tuples

This is the folder structure:
.
├── bolt_testing.py
├── init_processing_bolt.py
├── requirements.txt
├── src
│   ├── bolts
│   │   ├── generic_bolt.py
│   │   ├── init.py
│   ├── init.py
│   ├── storage
│   │   ├── cassandra_storage_client.py

│   ├── tuples.py
└── topologies
├── init.py
├── topology_one
│   ├── init.py
│   ├── normalize_data_bolt.py
└── topology_one.yaml

Is there any way of referencing classes outside the topology folder?
