I need to receive a plot of the next equation:

E:=0.001;

eq := E*(diff(y(x), `$`(x, 2)))+(x^2+1)*(diff(y(x), x))-x*(x-1/2)^2 = -x^2+2.7^x ;

/*(x=0..1, y(0)=-1, y(1)=0)*/

I try to use DEplot in such way DEplot(eq, y(x), x = 0 .. 1, y = -1 .. 0); but i always get a bug like 

Error, (in DEtools/DEplot) cannot produce plot, non-autonomous DE(s) require initial conditions.
