Generate Report not working

[lawrencedy1]

When I try to run the generate_report.py script I get the following:
Traceback (most recent call last):
File "generate_report.py", line 6, in
import chatstat
File "/Users/lawrence/Facebook-Messenger-Statistics/chatstat.py", line 2, in
from plotly.subplots import make_subplots
ImportError: No module named plotly.subplots

I do have plotly installed and it works fine on Jupyter Notebook. I'm using Mac OSX by the way.
