Hi, everyone. I used salicon-net (finetune-salicon.py)to try to train a new model over my own dataset. However, There is a error when I train my model. error: I1122 09:19:42.497810 16306 net.cpp:761] Ignoring source layer sec_pool5 I1122 09:19:42.497845 16306 net.cpp:761] Ignoring source layer custom_interpolation_layer working on 0 of 600 I1122 09:19:42.906407 16306 solver.cpp:228] Iteration 0, loss = 3359.02 I1122 09:19:42.906457 16306 solver.cpp:244] Train net output #0: loss = 3359.02 (* 1 = 3359.02 loss) I1122 09:19:42.906472 16306 sgd_solver.cpp:106] Iteration 0, lr = 1e-06 F1122 09:19:43.967656 16306 io.cpp:69] Check failed: proto.SerializeToOstream(&output) Check failure stack trace: Aborted (core dumped) I'm looking forward to your reply.

@CLT29 When I use cpu model to train, it success. But it down when I use gpu model.

CLT29 commented 8 years ago

This seems to be an issue with caffe. Did you check the solver prototxt and make the snapshot directory?

I have checked the solver prototxt and made the snapshot directory , but it still occurred this error. And then I used the original prototxt downloaded from the Github and set cpu pattern to run, it success.

@CLT29

zhangqiudan commented 8 years ago

Do I need to change the original prototxt to savethe caffemodel ?

CLT29 commented 8 years ago

Can you post your solver prototxt file? -chris

By the way, you have verified that you have enough disk space to save the snapshots (which can be 1GB each)?

yeah, I have verified the disk space is enough.

I just tried to remove the solver_type, It can run successfully. Thank you very much for solving the problem for me. Best wishes to you. by qiudan

CLT29 commented 8 years ago

You may want to try adjusting the learning rate (maybe slightly increasing it), since now you will be using SGD instead of ADADELTA. Be careful to monitor the loss to make sure the loss doesn't diverge and decreases if you change the learning rate. You may want to also try a different solver_type, such as ADAM.

Good luck. You may want to report this problem to Caffe, I do not know what causes this for you.
