Having trouble running the "Getting started" section (even the tests do not run)

Hi,

I am trying to run the KnowBert code but keep getting stuck with the following error when trying to run the tests or the “How to embed sentences or sentence pairs programmatically” snippet:

Steps to reproduce

1. Enter a clean anaconda docker container docker run -it continuumio/anaconda3
2. apt-get update && apt install -y g++ make
3. git clone https://github.com/allenai/kb.git
4. conda create -n knowbert python=3.6.7
5. source activate knowbert
6. pip install torch==1.2.0
7. pip install -r requirements.txt
8. python -c "import nltk; nltk.download('wordnet')"
9. python -m spacy download en_core_web_sm
10. pip install --editable .
11. pytest -v tests

Before running tests downgrading to overrides==3.1.0 and scikit-learn==0.22.2 solves the issue!

@leonodelee Hello, have you tried following the steps I give in my answers to issue #39 ? If so and you still have trouble, please provide error messages, or if there are none, a more detailed description of the abnormal behavior.

Thank you for your kindful help, I solved this problem by ‘pip install allennlp==0.8.2’ and other install instructions in https://github.com/allenai/kb/issues/39
