# There is in-feasibility issue in Gurobi

```
for r in Requests :
for i in plocs :
SIM.addConstr((quicksum (w[r,i,1,g,n] for g in tlocs for n in NodeVisits if w.get((r,i,1,g,n)) != None)
+ quicksum (y[r,i,1,j,n] - y[r,j,n,i,1] for j in locs for n in NodeVisits if y.get((r,i,1,j,n)) != None if y.get((r,j,n,i,1)) != None )
+ quicksum (v[r,i,1,j,n] - v[r,j,n,i,1] for j in locs for n in NodeVisits if v.get((r,i,1,j,n)) != None if v.get((r,j,n,i,1)) != None )) == Fr[(r,i)])
```

show me infeasible constraints but there is no synatic error but it's from formulation what can i do to solve it
