why all my output results of the fcn32 is ZERO

[daiyp3360xxxxxisxxxxxxmine]

after the fcn32 was trained for 9 epochs, the output value score of it is still zero. however, the weight of each layers are not zero. i am wondering if somebody has suggestions to fix this problem.

I think you should try using training data as validation data, and check if it works. If it doesn't work, that means you have a serious bug in your code.

I have the sane problem with fcn8s, help anyone?

Hi,Did you solved this problem?I trained 50 epoch,but when I use the trained model to test,the output is zero.

For training fcn8s, you first start training fcn32s and fcn16s.

Hi,I trained the fcn32 network,but I also has this problem,the output of the network is always zero.

I found that in the initialization function, weights are initialized to zero, which may cause the problem. Does anyone knows why the fcn8s need to initialize all the weights to zero?

Because of this https://github.com/wkentaro/pytorch-fcn/issues/40

I didn't solve this problem yet, for these days I was tracked by some trifles, I am just going to resume this work. I do think this problem might caused by the initial strategy. i will response here as soon as i solve this problem.

Hi，Did you solved this problem?Thanks!

I have the same problem with fcn32s, all output results are zeros. Anyone can help ?

Hi, @daiyp3360xxxxxisxxxxxxmine , have figure out the problem yet?

[songyuc]

Hi @wkentaro , I think #40 may have no relation to the initiation strategy, so it cannot account for the problem here.

I have same problem, did you solve it? @daiyp3360xxxxxisxxxxxxmine

can you run the code?i have lots of problems about this code.Could you please share me your code?My email：[email protected]。Thank you very much!!!
