learning rate and other hyper-parameters

[coolbay]

What learning rates are you using to train the model? I use the default hyper-parameters specified in the provided code and 4 GPUs to train the C3D model on THUMOS14. But I got a loss of NaN at [session 1][epoch 1][iter 301/3897]. I guess the hyper-parameters are not right. Could you please provide the hyper-parameters you used for training?

Thank you very much!
