It seems to be a none-Keras operation in your matting_l1_loss
implementation, whem I wraped 1. - ce_weight
in a Lambda function like KL.Lambda(lambda x: 1. - x)(ce_weight)
, it works fine.
Original Code
matting_l1_loss = KL.Lambda(lambda x: matting_weighted_l1_loss(*x), name="matting_l1")(
[input_fg_alpha_gt, matting_result, 1. - ce_weight])
Hi,When I run classifier training,This kind of problem happens?
i had encounter the same issue,when training on 'Fusion' model, have you solve the problem yet? @sanshibayuan
get code working by replaceing matting_l1_loss = KL.Lambda(lambda x: matting_weighted_l1_loss(*x), name="matting_l1")( [input_fg_alpha_gt, matting_result, KL.Lambda(lambda x: 1. - x)(ce_weight)]) with original code
Hi, I encountered this error when I tried to train on my toy datasets, do you have any idea why? Thanks a Lot !!
It seemed to be some problem when building the Fusion model, the inference stage and the classifier training are all good.
By the way, I'm running under keras==2.1.6, tensorflow==1.10 according to the readme file.
