Delete _ext.cpython-36m-x86_64-linux-gnu.so and build dir, then redo sh make.sh

Hi! I want to know what's you mean of build dir. Can U tell me about this command? First, I rm -rf this _ext.cpython.xxx file, Then I redo sh make.sh. But this issue has not been solved.

Delete “_ext.cpython-36m-x86_64-linux-gnu.so and build“, install pytorch by source code, or update your gcc to version 4.9. Since pytorch 1.1 was built with gcc 4.9 when install by pip.
