Incompatible attr in node fpn_p4_sum at 1-th input: expected (1,256,50,158), got (1,256,50,157)

Hello I am trying to train FPN on my own dataset and I am getting the below error: Can anyone please have any idea about it?

The error is: mxnet.base.MXNetError: Error in operator fpn_p4_sum: [13:14:48] src/operator/nn/./../tensor/../elemwise_op_common.h:122: Check failed: assign(&dattr, (*vec)[i]) Incompatible attr in node fpn_p4_sum at 1-th input: expected (1,256,50,158), got (1,256,50,157)

N.B-> I have already successfully trained Deformable FRCNN and RFCN on the same dataset.

you image dim must divided by 32.

@chinakook : Finally it works fine by selecting the image size 32 divisible!! Thanks a lot!!
