PyTorch implementation of "Seed, Expand, Constrain: Three Principles for Weakly-Supervised Image Segmentation", ECCV2016
I don't know why the model after being trained in train.script always generates all-0 value maps, but I test the best model you provide shows the result is right...
First of all, Thank you for your hard work. I am familiar with Pytorch, so your work is very helpful.
I am curious about the condition that you got the performance (mIoU 50.6049 and mIoU 49.6978) you mentioned. When I download the weight and evaluate it, I get the same result as the performance you mentioned.

However, if I try to train from scratch, I cannot get the same result. This is the result of testing by saving the checkpoint when the loss is minimum without changing the hyperparameter setting.

The learning loss is shown below. Even if I change the hyperparameters, the sum of losses converges to 6.xx (seed loss 2.xx, expand loss 4.xx, constrain loss 0.5xx). It seems that training is not working in my case.
What I'm curious about is your learning loss decreasing well? What is the saving checkpoint criteria? (minimal loss or something?)

Can you tell me how do you get the localization_cues.pickle.gz of COCO ? Thanks.
After I run test_multiprocess.py, the generated pred_images are all black. What is the reason for this?
