Build Pytorch from source failed

I’m trying building pytorch from source following this instruction. However, I encounter an error below, what am I missing?

In file included from ../caffe2/contrib/aten/aten_op.cc:1:0:
./caffe2/contrib/aten/aten_op.h: In lambda function:
./caffe2/contrib/aten/aten_op.h:9551:33: error: ‘pstrf’ is not a member of ‘at’
               auto the_result = at::pstrf(self, upper, tol);
                                 ^

               auto the_result = at::pstrf(self, upper);
                                 ^

                                 ^

Could you try to sync and update the submodules again, run python setup.py clean and rebuild it again?

@ptrblck yeah, it works. Thanks!
