Problem description:
I am running this project(research-summarization) in PyCharm with the following environment:
Windows-10
Python 3.5.6 |Anaconda, Inc.| (default, Aug 26 2018, 16:05:27) [MSC v.1900 64 bit (AMD64)]
NumPy 1.14.2
SciPy 1.1.0
gensim 3.8.1
FAST_VERSION 1

I am running this project with the default configuration:
"The Opinosis dataset is included, and main.py is configured to run on this dataset by default."
But I got the following problems, I need some advice for debugging.
Thank you very much.
