Same discharges after running calibrate_vic_sceua.py #37

Hi there,

First, truly great codes and tutorials for VIC learners!

Well, I got a problem with running calibration. I set the sample to 100, but the output _calibrationSCEUA.csv file contained totally the same discharges in that 100 simulations while the parameters were different.

I'd greatly appreciate it if you had time to explain it. Thank you!

I check the process, and the issue might arise from the routing code. I already solved the error about "IndexError: Index exceeds dimension bounds" in _routevic.py, but I can't figure out why different parameters ('binfil Ws Ds...') got the same discharges. I'll try to debug it then.
