iot-weather-station example on my omega2,

the document stated "The Omega’s firmware along with this project and its dependencies will require approximately 18 MB of storage space. If you wish to install apps on the Console such as the Editor, we recommend booting the filesystem from an external SD card or USB drive." did you have filesystem on sd card or usb drive? most likely it would also be best to create a swap space, have you followed onions instructions for creating a swap space?
https://docs.onion.io/omega2-docs/extending-omega-memory.html
and also, booting from external storage/ setup overlay.

Thanks for your feedback. I created more swap space on my omega 2 and I was able to install the IoT Watson Example.

Thank you.
