How to load doctr pytorch weights

[pokecheater]

Hi DocTr-Team/Community,

Inside the tutorial on how to export/import a model everything is only explained for tensorflow:
https://mindee.github.io/doctr/using_doctr/using_model_export.html

It is really straightforward. But how should I do this with pytorch?
It is not explained.

Thx in advance
