OOM when allocating tensor with shape[32,4,16,1024] and type float on /job:localhost/replica:0/task:0/device:CPU:0 by allocator cpu
[[{{node model_1/model/resnet50/conv4_block6_3_bn/FusedBatchNormV3}}]]
Hint: If you want to see a list of allocated tensors when OOM happens, add report_tensor_allocations_upon_oom to
RunOptions for current allocation info. This isn't available when running in Eager mode.
