I run moving_average.py again with Python 2.7.12. But it fail now. But moving_average.py can be run after I type "pip install -U grs" on Dos terminal first time.
My moving_average.py is as follows.
from grs import Stock

stock = Stock('6278')
tuple = stock.moving_average(1)

The error log is as follows.
