reproduce retrain result

[zhanglei1172]

Using the architecture results from the README search((2, 1, 0, 1, 2, 0, 2, 0, 2, 0, 2, 3, 0, 0, 0, 0, 3, 2, 3, 3)), and using the Retrain code from the repository (with no additional modifications), I ended up with [11 02:26:43] te s t iter 301250: Loss = 2.017752, top-1 ERR = 0.262860, Top-5 ERR = 0.084000, val_time = 71.723475. This is a little different from the TOP-1 error=25.6 reported by the repo. Have you re-run the evaluation code of the repo to get similar results?
