在[base_conv_layer.cpp:122]上获取错误检查失败:channels_%group_ == 0(1对0),如何解决?

当我尝试为我自己的数据训练FCN32 semantic segmentation时,我收到此错误:

    I0106 12:57:53.273977 19825 net.cpp:100] Creating Layer upscore_sign

我没有包含先前图层的创建。但似乎net成功创建了以前的图层,并且它到达Creating Layer upscore_sign,错误就出现了。我更改了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改为5(基于我数据中的类数):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?我的错误是什么/在哪里?

感谢您的帮助。

检查失败:channels_%group_ == 0(1对0) 这条线真的很重要!你应该检查你的num_output和group,看看channels_%group_ == 0。
