module 'faiss' has no attribute 'IndexFlatIP' (faiss sources)

OS: ubuntu 16.04 (Docker)

Reproduction instructions

I install sensegram:

git clone https://github.com/tudarmstadt-lt/sensegram.git
make
cd sensegram
pip3 install -r requirements.txt
python3 -m spacy download en

is fine.
Then install faiss like in Makefile:

apt-get update
apt-get install swig libopenblas-dev python-dev gcc g++ python3-pip unzip
rm -rf faiss
git clone https://github.com/facebookresearch/faiss.git
cd faiss
./configure
make -j$(nproc)
apt install curl
make test
make py

Finished - ok, but with little warning: "unused variable"

then i run train-wikipedia-sample

cd ..
wget http://panchenko.me/data/joint/corpora/wiki.txt.gz -P model
bash train.sh model/wiki.txt.gz

error:
