Error while installing from a local clone of tiny-cuda-nn #447

Closed silky1708 closed 3 months ago

silky1708 commented 3 months ago

While installing tiny-cuda-nn using a local clone (Ubuntu 22.04) as follows:

git clone https://github.com/NVlabs/tiny-cuda-nn.git
cd bindings/torch
python setup.py install

I got the following error:

cc1plus: fatal error: ../../dependencies/fmt/src/format.cc: No such file or directory
compilation terminated.
error: command '/usr/bin/gcc' failed with exit code 1

PyTorch v2.3.0 (as recommended) torchvision v0.18.0 cuda 11.8 (I got the following warning while installing: UserWarning: The detected CUDA version (11.5) has a minor version mismatch with the version that was used to compile PyTorch (11.8). Most likely this shouldn't be a problem.) g++, gcc version 11.4.0 path to cuda set:

export PATH="/usr/lib/cuda/bin:$PATH"
export LD_LIBRARY_PATH="/usr/lib/cuda/lib64:$LD_LIBRARY_PATH"

Inside tiny-cuda-nn/dependencies/, delete and clone the following repositories from scratch:

rm -r cutlass
rm -r fmt
git clone https://github.com/NVIDIA/cutlass.git
git clone https://github.com/fmtlib/fmt.git

This solved the issue for me.

More issues come up later:

To solve this, I followed this comment and finally installed tinycudann successfully!
