fixes #131

Might be cleaner to import only the needed function(s) (like the other eole.utils import below it), thanks! (And it will also make flake happy.)

[isanvicente]

Should be done now, not sure why flake is still complaining. Details say :

would reformat eole/trainer.py

Oh no! 💥 💔 💥
1 file would be reformatted, 150 files would be left unchanged.
Error: Process completed with exit code 1.

However a single line has been added to the file...

[francoishernandez]

You just need to apply the black formatter (either on the full code black . or here black eole/trainer.py would be sufficient).

[vince62s]

when importing the function you need to remove the full path where they are used.
this is the reason why I don't really understand the initial error
