4 years ago KeyError: 'exp_avg'
Try to reproduce it for myself and return.
What about SGD:
RuntimeError: The size of tensor a (100) must match the size of tensor b (3) at non-singleton dimension 3
Incompatible sizes of the tensors in checkpoint. Which sizes of the input tensor of the net? Which sizes of the checkpoint parameters??
I have tried to resume training on a checkpoint that was created by jwyang's repository using -r flag. The checkpoint was trained for 50 epochs and now I want to train it for 20 more epochs. However, I get the following error when I try to train with ADAM optimizer.
python run.py train --net resnet101 --dataset voc_2007_trainval -r --epoch 50 --total_epoch 70 --cuda -o adam

Any help would be appreciated.
