missing requirements statements

[hahahannes]

Hello :)

after creating a new conda env with conda create --name cognival python=3.7 and installing the requirements with pip install -r requirements.txt I got an error saying that tensorflow is missing. In the requirements.txt history I saw that 1.15.2 was the latest used version. Maybe we should add it? I tried 2.5.0 out of curiosity but got some problems with missing losses in the model history object.

After installing cognival python setup.py install I got the error ArrayField.empty_field: return type None is not a <class allennlp.data.fields.field.Field> from allennlp. Suggested by this thread I installed pip install overrides==3.1.0 which solved the error.
