Resolution in evaluation

[Leequens]

Hi, Thanks for your works! @hellochick
I get a problem when I use your model and evaluate.py to evaluate my image in cityscape.
If I use 20481024 resolution, it can get a normal result.
But If I use 1024512 resolution, it will get a very low mIoU, about 0.04.
If I resize labeTrainIDs to 1024512, it will get a error: label out of bound. Is this error related to the model?
Can I only use 20481024 resolution images if I use your model to evaluate?Thanks.
