What's the current state of the art of managing multiple virtual environments, running tests and running your application?
On Ubuntu and Windows I use Poetry [0], and it works, although it has (had?) some quirks during the installation on Windows.
I liked its portability and lockfile format though.
A few years ago I used conda [1], which was nice because it came batteries included especially for Deep Learning stuff.
I switched because it felt way to heavy for porting scripts and small applications to constrained devices like a Raspberry Pi.
And then there are also Docker Images, which I use if I want to give an application to somebody that "just works".
What's your method of choice?
