about scale_lr

[roywithfiringblade]

In the experiment setting of PASCAL-5i, the initial lr is setting to 0.0025. But i saw that there was a scaler_lr in the poly_learning_rate(). And the default value is 10. So the initial lr is actually 0.025. right?

@704051419 In train.py, the index has been set as -1 which means the initial lr is scaled for all learnable parameters.

Thank you for mentioning it and sorry for the inconvenience.
