[BUGFIX] Fix GUI (#533)

* Fix GUI

Fix version parsing
Add more tests for version class

* Update train/_version.py

Better error message

* Add hello world CLI entry point to verify installation

* Simplify install process for testing

* Hack for CI/CD version determined by pyproject.toml

* Clean up development

Remove environments/requirements.txt
Add docuemntation recommending to use Anaconda environment definitions.
