R install not working on Windows #1

Closed MartinGuth closed 9 months ago

MartinGuth commented 4 years ago

Hi Thierry,

thank you for providing the code for the LSBoost algorithm. I just tried to install the R-package, but it is not working!

I followed the steps outlined:

library(devtools)
devtools::install_github("thierrymoudiki/mlsauce/R-package") # also tried it with "Techtonique/mlsauce/R-package"

However, it seems that it actually tries to install the Python version of the code:

Then the installation carries on collection Python packages, but it fails at executing Python.exe:

thierrymoudiki commented 4 years ago

Hi Martin,

Thanks for this great first issue; clearly explained, and detailed.

This is true: "it seems that it actually tries to install the Python version of the code:". It works on Linux and macOS, but unfortunately, I use to encounter problems at the intersection R x Windows x reticulate. reticulate does the translation from Python to R. Do you have it? I can't see it in your list of loaded packages. After that, we could investigate further.

This error is quite disturbing though: "No module named 'numpy.distutils._msvccompiler' in numpy.distutils; trying from distutils". What would be your take on that? (if you're into Python)

thierrymoudiki commented 4 years ago

PS: When did you post your comment? I just commented, on Thursday, September 10 @ 10:35 am, Paris, and it seems to indicate that I did it 9 hours ago...

MartinGuth commented 4 years ago

Hi Thierry,

sorry for the delay in replying!

I installed the rerticulate package and tried installing the mlsauce package again, but it still gave me the same error. I then re-installed Python (v3.8.5/64 Bit) with the default settings and paths - still got the error.

I went back to the error message in the R console and did tried solving the issues step-by-step:

But I am still stuck at:

Any idea how to proceed?

P.S. you've answered my last comment right away :)

thierrymoudiki commented 4 years ago

Hi Martin,

Would you try a few things mentioned in the following page?

https://rstudio.github.io/reticulate/articles/versions.html

Such as use_python to specify the executable? Before installing. And check py_config(), py_discover_config() to see what is used.

thierrymoudiki commented 3 years ago

Hi Martin, @MartinGuth,

How did it go?

Would you uninstall everything and try again now?

VladPerervenko commented 3 years ago

Starting from version 0.5, the package in Windows is not installed either through R or through Python. Finally, indicate in the project description that it is intended only for Linux. People are wasting their time pointlessly. Good luck

thierrymoudiki commented 3 years ago

@VladPerervenko one constructive way would be to contribute a solution for Windows, if you know how to fix this. I'm not paid to create mlsauce.

VladPerervenko commented 3 years ago

As far as I remember, problems with version 5 were associated with the use of the JAX compiler. At that time (it was a long time ago), this compiler only worked under Linux. Now I see that it can be installed under Windows as well. True, dances with a tambourine will be required. If you haven't changed anything drastically and are still using JAX, I will try to install it on Windows and install your package. He is very interesting to me. Good luck

thierrymoudiki commented 3 years ago

@VladPerervenko If it's interesting to you, then we can try to find a way. It'd be cool if you could post the error messages here (as a starting point). So that we can investigate.

VladPerervenko commented 3 years ago

When installing in Python, I get errors mlsauce08_Err.txt Maybe there is a problem here? ValueError: 'mlsauce\demo' is not a directory

VladPerervenko commented 3 years ago

I am not a pythonist. I cannot determine where and what the error is. sorry

thierrymoudiki commented 3 years ago

@VladPerervenko, Ok, can you try again now, (pip install mlsauce --upgrade), and report the error message, if there's any? Please make sure that it's mlsauce's version 0.8.1.

When installing a package in R, will the environment in Python be detected automatically? Or do you need to activate it first? Good luck

thierrymoudiki commented 3 years ago
VladPerervenko commented 3 years ago

I have not installed in R. Today I will check from Python via Reticulate.

Again we come here ... https://jax.readthedocs.io/en/latest/developer.html#additional-notes-for-building-jaxlib-from-source-on-windows

thierrymoudiki commented 3 years ago

@VladPerervenko , thanks for your feedback. So, what would you suggest for R+Windows? For example, import jax conditionnally to the system (Windows, macOS, Linux), or something else? (e.g include your last comment in the README? etc.)

VladPerervenko commented 3 years ago

I see two options:

  1. Indicate in the package description that for installation in Windows you must first install the JAX library. And give a link to the page where the installation is scheduled.
  2. While installing the package in R, check:
    • OS Windows? If yes
    • you need to install the JAX library. Install?
    • perform the installation automatically. The second option is probably very difficult or even impossible. It highly depends on the specific configuration of the computer. I'll try to install Jax on the weekend. If possible, I will describe the result. Good luck.

thierrymoudiki commented 3 years ago

Hi @VladPerervenko, I appreciate the effort, thanks. Could you give it a try now, please (version 0.8.2)? I was previously importing 'jax' at the wrong place, in a LSBoost file. Actually, you don't need to have jax installed on Windows yet.

How to install a package in R, You need to think. In python, a package "mlsauce" can already be installed in any environment. I have it set to env/ mlsauce/

thierrymoudiki commented 3 years ago

@VladPerervenko so, it works on your Windows machine now, right?

I don't get this part: '> How to install a package in R, You need to think. In python, a package "mlsauce" can already be installed in any environment. I have it set to env/ mlsauce/'

thierrymoudiki commented 3 years ago

@VladPerervenko and @MartinGuth: Shall we close the issue now? @VladPerervenko Would you like to guest blog this on my page https://thierrymoudiki.github.io/blog/? ('How to install on Windows')

VladPerervenko commented 3 years ago

I think it's early to close. Have someone install the package in R according to your instructions. For example @MartinGuth . If everything works out, then close it.

VladPerervenko commented 3 years ago

What exactly did you want and what did I post on your blog. My English through a translator is not very clear. If only codes with short comments.

thierrymoudiki commented 3 years ago

@VladPerervenko Yes, code with short comments. And I'll do the rest.

Probably a problem with the brotli module. By the way, the same error when trying to install nnetsauce in R. But unlike nnetsauce, mlsauce is installed in Python and works fine in R through reticulate.

__What do they mean in english?__

PS: I've just tried to install both mlsauce and nnetsauce in a fresh environment on RStudio Cloud (Ubuntu OS), and it works
