Report for GSoC 2021 (Gradually Typed Hasktorch)

This is the final report for the GSoC 2021 project - Gradually Typed Hasktorch. Gradually Typed Hasktorch is a new tensor API for Hasktorch. It has been initiated by my mentor, Torsten Scholak, and as part of GSoC I helped with streamlining this new API.

Student: Julius Marozas Mentor: Torsten Scholak
