Hi @yunfan, I think that is because an "output" directory hasn't been created before the make.sh is running.

As described in the "Build and Test" part of the README.md:

$ mkdir output
$ bash make.sh
$ cd output
$ bash ../test.sh

Do you mind to try again? Please let me know if such issue still exists. Thanks a lot.
