Here is a simpler example that does not work for me. what error am i doing?

import chart_studio.plotly as py

import plotly.express as px

import pandas_datareader as pdr
import datetime

vale3 = pdr.get_data_yahoo(‘GOOG’,
start=datetime.datetime(2016, 10, 1),
end=datetime.datetime(2019, 1, 1))

Daily log returns

daily_log_returns = np.log(vale3.Close.pct_change()+1)
display(vale3.Close ).head(10)
fig = px.line(vale3.Close, x=‘Date’, y=‘vale3.Close’)
fig.show()
