I finished these steps:

$ git clone --recursive https://github.com/nvlabs/tiny-cuda-nn
$ cd tiny-cuda-nn
tiny-cuda-nn$ cmake . -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo
tiny-cuda-nn$ cmake --build build --config RelWithDebInfo -j
tiny-cuda-nn$ cd bindings/torch
tiny-cuda-nn/bindings/torch$ python setup.py install

The final message printed is

No bug. Then I failed to import the tinycudann. My command is:

import tinycudann as tcnn

And the error is:

>>> import tinycudann as tcnn
