+**For windows users it's hard to make everything works correctly**, so I recommand using the first option or this `dataflow.yml`:
+
+```yaml
+nodes:
+  - id: talker
+    path: powershell
+    args: ./.venv/Scripts/python nodes/talker.py
+
+  - id: listener
+    path: powershell
+    args: ./.venv/Scripts/python nodes/listener.py
+```
+
+**Note**: you may need to execute this command `Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Bypass -Force;` as Admin
+
