the learning rate in log_train times 0.1

[yibuxulong]

I found the lr in log_train.csv is multiplied 0.1, and I found in the line marked TODO was written like this
data_time=data_time, loss=losses, top1=top1, top5=top5, lr=optimizer.param_groups[-1]['lr'] * 0.1)) # TODO
also can be seen in:

I wonder why lr times 0.1?
