Hi I was trying the exactly same code from this github:https://github.com/alexis-jacq/Pytorch-Sketch-RNN/blob/master/sketch_rnn.py
and I tried to run the cod on Jupyter notebook.
Still it seems to me that it doesn’t operate because at this part
if __name__=="__main__":
model = Model()
for epoch in range(50001):
model.train(epoch)
I have an error saying
epoch 0 loss 2.6120107173919678 LR 2.6110057830810547 LKL 0.0010049500269815326

Would you mind if you help me out with this?
