Problems encountered when installing torchsparse

[hlh2001]

As mentioned in the paper, training with 3090 is feasible. Installing CUDA10.2 in 3090 is difficult. So I'm using CUDA11.3, Python3.7.10, pytorch1.10.1. The previous steps performed according to installation, and detectioin was added to PYTHONPATH, but when executing the last step, "pip install./torchsparse-u/", the error is as follows

Processing ./torchsparse-u Preparing metadata (setup.py) ... done Building wheels for collected packages: torchsparse Building wheel for torchsparse (setup.py) ... error error: subprocess-exited-with-error

× python setup.py bdist_wheel did not run successfully. │ exit code: 1 ╰─> [112 lines of output] ... subprocess.CalledProcessError: Command '['which', 'c++']' returned non-zero exit status 1. [end of output]

note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for torchsparse Running setup.py clean for torchsparse Failed to build torchsparse ERROR: Could not build wheels for torchsparse, which is required to install pyproject.toml-based projects

What might be the cause of this problem? Could you please give some reference configuration advice on using CUDA11.3 installation project environment on 3090?Besides,is the requirement.txt exactly the same as the requirement.txt in CenterPoint?

Hi. I just tried to re-install the ./torchsparse-u by pip install ./torchsparse-u/ on a 3090 machine, and it worked with the attached environments. According to your log, it seems like an issue with the version of g++. My gcc/g++ versions are both 7.5.0, with the system version Ubuntu 18.04 (This should not have a significant impact, I guess). Hope this can help you. environments_for_cu113_seg.txt environments_for_cu113_det.txt

Thank you very much for your answers. torchsparse is now installed. This is a problem with my system Settings,When I type ninja -v,it shows ninja: error: loading 'build.ninja': No such file or directory.When I type ninja --version,it shows 1.11.1.git.kitware.jobserver-1. My error was ninja: build stopped: subcommand failed .So I made a change in setup.py,that is cmdclass={'build_ext': BuildExtension.with_options(use_ninja=False)},then it works by pip install ./torchsparse-u/ besides,my gcc/g++ versions are both 9.5.0,with the system version Ubuntu 22.04.Thank you very much for your answers again!

That's Nice. Feel free to contact me if you have any other questions.

Hello, I wonder if APEX is necessary, as it shows no apex \no Tensorflow \Deformable Convolution not built.

Hi, APEX is optional and we did not install it.
