Cannot run evaluation.py

Traceback (most recent call last): File "/usr/lib/python3/dist-packages/torch/utils/cpp_extension.py", line 1666, in _run_ninja_build subprocess.run( File "/usr/lib/python3.8/subprocess.py", line 516, in run raise CalledProcessError(retcode, process.args, subprocess.CalledProcessError: Command '['ninja', '-v']' returned non-zero exit status 1.

The above exception was the direct cause of the following exception:

Ok, so I found out it was because I hadn't installed the C++ pybind11 library. Pip only installs the python library and on Ubuntu 20.04 it doesn't seem to be available through apt-get so I had to clone the pybind github repo and make it myself. Works fine now.

Could you describe how to solve this problem step by step? Which repo did you used?
