computed output size would be negative

[vijtad]

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

hi, do you solve the problem? I have the similar error.

[bohelion]

I have the same error.Have you solved this problem?I need your help,thanks.

[alyato]

I also meet the same problem. But i check my code carefully, finding the number of images are setted wrong. Can help your guys hopefully. thanks.

[R-Miner]

I had the same problem. For me the image size was not correct.

[zBabar]

can you please share more info regarding where we can make amendments to get it through
