File gem/utils/embed_utils.py does not exist in repository

Describe the bug
While trying to run the script gem/experiments/exp.py script, I got the following error:

Traceback (most recent call last):
    File "exp.py", line 19, in <module>
        from gem.evaluation.evaluate_link_prediction import expLP, expLPT
    File "/home/{username}/GEM-Benchmark/gem/evaluation/evaluate_link_prediction.py", line 12, in <module>
        from gem.utils import embed_util                                                                                                                                                                               ImportError: cannot import name 'embed_util' from 'gem.utils' (/home/{username}/GEM-Benchmark/gem/utils/__init__.py) 

The file gem/utils/embed_utils.py doesn't seem to be in the master branch of the repository.

To Reproduce
Steps to reproduce the behavior:

1. Execute command git clone https://github.com/palash1992/GEM-Benchmark
2. navigate to GEM-Benchmark
3. Rename the directory gem-ben to gem
4. Execute command pip3 install -r requirements.txt --user
5. Execute command export PYTHONPATH=$PYTHONPATH:/home/{username}/GEM-Benchmark
6. Navigate to gem/experiments/
7. Execute command python exp.py

Expected behavior
The script exp.py to run without errors.

Desktop:

• OS: Ubuntu 16.04
• Python: 3.6.9

Additional context
I had the project GEM installed but it was preventing this project from running so I had to first uninstall it. Figured I'd mention this detail. Also, the file wouldn't run without me changing the directory GEM-Benchmark/gem-ben to GEM-Benchmark/gem.

Thank you.

I also noticed this, but it seems embed_util is not used, so probably that line can be removed
