Error Installing Dependencies for Magic123 on Google Colab

[RoenTh]

I am trying to run the Magic123 model in a Google Colab, but I am encountering installation errors for several packages (raymarching, shencoder, freqencoder, and gridencoder). The installation fails during the execution of install.sh, with the following error for each package

Installing collected packages: raymarching
error: subprocess-exited-with-error

× Running setup.py install for raymarching did not run successfully.
│ exit code: 1
╰─> See above for output.

note: This error originates from a subprocess, and is likely not a problem with pip.
Running setup.py install for raymarching ... error
error: legacy-install-failure

× Encountered error while trying to install package.
╰─> raymarching

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure."

And when tryingto install them with pip setup.py install i get this error:

install_log.log

Edit: I found someone's work on the Internet, trying Magic123 in GooleColab like me, but when I compile this notebook, I get the same error as well. They didnt seem to have this error when the notebook was created.

Any tips or advice on resolving this issue would be greatly appreciated. Thank you in advance for your help!

Found the solution, the problem is related c++14 not working on google colab.
To solve the issue change c++14 to c++17 in setup.py of raymarching, shencoder, freqencoder. it should look like this:
import os
from setuptools import setup
from torch.utils.cpp_extension import BuildExtension, CUDAExtension

_src_path = os.path.dirname(os.path.abspath(file))

nvcc_flags = [
'-O3', '-std=c++17',
'-U__CUDA_NO_HALF_OPERATORS__', '-U__CUDA_NO_HALF_CONVERSIONS__', '-U__CUDA_NO_HALF2_OPERATORS__',
'-use_fast_math'
]

if os.name == "posix":
c_flags = ['-O3', '-std=c++17']
elif os.name == "nt":
c_flags = ['/O2', '/std:c++17']
