当我尝试对自己的数据FCN32
进行语义分割训练时,出现此错误:

我没有包括以前图层的创建。但似乎net
成功创建了先前的图层,并且达到了Creating Layer upscore_sign
,错误来了。我更改solver
如下:
net: "train_val.prototxt"
#test_net: "val.prototxt"
test_iter: 200 #3000 #5105
# make test net, but don't invoke it from the solver itself
test_interval: 1000
display: 20
average_loss: 20
lr_policy: "step" #"fixed"
# lr for unnormalized softmax
base_lr: 1e-10
# high momentum
momentum: 0.99
# no gradient accumulation
iter_size: 1
max_iter: 300000
weight_decay: 0.0005
snapshot: 2000 #10000
snapshot_prefix: "snapshot/FCN32s_train"
test_initialization: false
solver_mode: GPU #+
我将输出数量从 60 更改为 5(基于我的数据中的类数):convolution_param {num_output: 5 }
有人可以就此提出任何解决方案或想法吗?我错误地设置/更改了什么?什么/我的错误在哪里?
感谢您的帮助。
