It appears that you have a variable with
a categorical measurement level, and it is a constant, possibly due to
missing data causing case deletion. If you can't find the variable,
try running a very small problem - just one variable, and adding others
one at a time.

Y is continuous variable,
X1 is continuous variable,
X2 is category variable,and the x2 is 1,2,3.
X3 is category variable,and the x3 is 1,2,3,4. and so on.
I want to use the quantile regression,wheather or not I change the X2,X3 into dummy variable.
