Error Installing Dependencies on Google Colab

[RoenTh]

Description

I am trying to run the code in a Google Colab notebook, 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.

have u solved this problem?

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']
