# AmericasNLP 2021 Shared Task on Open Machine Translation

This is the official repository for the [AmericasNLP 2021 Shared Task on Open Machine Translation](http://turing.iimas.unam.mx/americasnlp/st.html). All scripts have been tested with Python 3.8.5, and requirements will be updated accordingly.

A example of data in the shared task's format can be found in ```pilot_data/```, and ```evaluate.py``` is an example of the metrics and evaluations that will be used for submitted MT systems.
