I am really new here but I have managed to train (i think) my own DeepLab model with my custom dataset in coco format:
(Epoch 3, training loss 0.165: 100%|█████████████████████████████| 70/70 [12:10<00:00, 10.44s/it]
Epoch 3, validation pixAcc: 0.872, mIoU: 0.436: 100%|█████████████████████████████| 5/5 [01:04<00:00, 12.89s/it]
Epoch 3 validation pixAcc: 0.872, mIoU: 0.436)
Howewer I cannot run it successfully
I’ve not been able to find tutorial about training and using my own DeepLab model so I have adapdet some found logic to get it processing my images on cpu without exeptions
But now I am stuck
Every time a get the same empty result
Maybe the problem is the same as here:
About running on CPU and stuff, but I have managed to use GPUs only in training process, not in the running. And I don’t know how to do that
Maybe I have done all wrong
Could you get me some advice?
Thank you
