> The following code (print the 'not' of a boolean input value through MLContext) currently throws an error:
> {code}
> @Test
> public void testDisplayBooleanNotDML() {
> 	System.out.println("MLContextTest - display boolean 'not' DML");
> 	String s = "print(!b);";
> 	Script script = dml(s).in("b", true);
> 	ml.execute(script);
> }
> {code}
> This gives the following error:
> {code}
> Caused by: org.apache.sysml.lops.LopsException: ERROR: line 2, column 6 -- Problem generating simple inst - CP°!°b·SCALAR·DOUBLE·false°_Var1·SCALAR·BOOLEAN
> {code}
> This can most likely be fixed by explicitly setting the value_type for scalar input values through the MLContext API in the Script class.
