Let f(x) be a function defined on R ( The set of real number) Such that ${\mathrm{f}}^{\mathrm{\prime }}\left(\mathrm{x}\right)=2015(\mathrm{x}-2014)(\mathrm{x}-2015{)}^2(\mathrm{x}-2016{)}^3(\mathrm{x}-2017{)}^4$ For all x $\in$ R if g (x) is a function defined on R with its values in the interval (0,$\infty$) such that $\mathrm{f}\left(\mathrm{x}\right)=\ln \left(\mathrm{g}\right(\mathrm{x}\left)\right),\mathrm{x}\in \mathrm{R}$, Then the number of points in R at which g (x) has a local maximum is
