Error installing rerf Windows 10 (python)

[Merudo]

Describe the bug
I am unable to install rerf on Windows 10 (python).

I tried updating pip, setuptools, and wheel, and reinstalling Visual Studio BuildTools but nothing seems to work.

To Reproduce
Type pip install rerf to install rerf.

I get the following error:

Expected behavior
The package should install properly.

When will this be available for use on Windows (not WSL) please?

I have been getting the same error in both windows and ubuntu when calling pip install rerf

I am missing something?

Env
Windows 10, Ubuntu 18.04 with anaconda

Env

Successfully running on Ubuntu machine

To correct my self I was trying to install the rerf package using WSL 2 on windows but I kept receiving this error. I then used another machine with Ubuntu installed and everything went fine.

OS

• both ubuntu 18.04 and 16 version. (I have not tried on 20. v )

steps as explained in the doc i just added the first command
$ sudo apt-get install
$ sudo apt-get install build-essential cmake python3-dev libomp-dev libeigen3-dev
$ pip install rerf

Note: By default when using sklearn random forest, the y variables are encoded if they are categorical, for the case of Rerf the package doesn't do that automatically. So don't forget to encode your y variable else you may get null output eg when using cross_val_score method. (i used sklearn labelEncoder for encoding my y variables).

[pepetikesavasiddhardha]

Identified my mistake, Thanks @burhr2 for the idea initially we have to install a virtual environment in the google colab notebook then we have to use following commands for installing rerf library
!sudo apt-get install
! sudo apt-get install build-essential cmake python3-dev libomp-dev libeigen3-dev
! pip install rerf
Then these 3 commands will finish the task of installing rerf library which we use for oblique random forest implementation.
Then we can import it and use rerf classifier/regressor as per our need.
import rerf
from rerf.rerfClassifier import rerfClassifier

Important thing to note here is it is better to create a virtual environment in colab notebook before installing library as I faced some problems because of it and process will be smooth if u install virtual env and work in it. Also these lines of code will work in both windows/Linux, also I think it would work on macOS but not exactly sure
