computed output size would be negative

vijtad commented 7 years ago

I am getting following error when I am running sticker example in Windows 10/Python 3.5/TF 0.1.

computed output size would be negative

     [[Node: fcn_8s/vgg_16/fc6/convolution = Conv2D[T=DT_FLOAT, data_format="NHWC", padding="VALID", strides=[1, 1, 1, 1], use_cudnn_on_gpu=true, _device="/job:localhost/replica:0/task:0/cpu:0"](fcn_8s/vgg_16/pool5/MaxPool, fcn_8s/vgg_16/fc6/weights/read)]]
