I've downloaded the pretrained model from web and ran it again using 8 gpus, got 72.9.
Have you tried other pretrained model? Did they get the right result?
from tf-cpn.
Thx you for your answers,
The results I'm reporting is with the pretrained model and not my training. I only have tried res101.384x288 and res50.256x192 and the results are approximately the same(I've just reported res101.384x288).
qualitatively, the model works on simple cases but it does a lot of errors for more complicated cases.
I will try the other models and will also try to train(with 2 Titan X and 1 GTX 1080 )
from tf-cpn.
Do you check the validation dataset?

Ok, I've re downloaded pre trained model and I've re tested everything.
and actually res50.256x192 has good results (as it is indicated) !
However the other methods failed (res50.384x288, and res101.384x288). So the problem might come from the input size.
Is it possible that it is a problem of hardware(because I only use 3 GPUs) ?
I put the details here(with pretrained model):

I think it can't be the problem of hardware. Since it's worse in 384x288 size, did you run the pre-trained model in the corresponding model folder?
from tf-cpn.
I found the mistake. I modified config and with silly copy-pastes I put the wrong i input size in the two networks. My Bad !
However, I still don't understand why is there this huge difference of results if I put a wrong input size for testing.
But thank you very much for helping me !
