python setup.py develop builds everything as per CONTRIBUTING.MD. I’m currently using this
DEBUG=1 USE_DISTRIBUTED=0 USE_MKLDNN=0 USE_CUDA=0 BUILD_TEST=0 USE_FBGEMM=0 USE_NNPACK=0 USE_QNNPACK=0 USE_XNNPACK=0 python setup.py develop

My query is for example if a breaking change is introduced in Pytorch, for example here,
AttributeError: module 'torch' has no attribute 'true_divide'

true_divide will become part of 1.5. But now after importing torch, it throws this error. So instead of building again, how can I only build the change that has been recently introduced. So now when I run develop command, it compiles [124/620] 620 other binaries also which means some things are getting compiled again even though they have been compiled.
