`reticulate::py_config()` does not find python library when it is already installed #1062

njtierney · 2021-10-04T06:53:17Z

I can see the r-miniconda and r-reticulate belw, but when I try and check the py_config() it doesn't detect them. I'm not sure how to fix this?

reticulate::conda_list()
#>           name

#> 2 r-reticulate

What happens if you try use_conda("r-reticulate", required = TRUE)? Or use_python("/path/to/miniconda/env/bin/python", required = TRUE)? (And then py_config() to force Python to be initialized.)

njtierney · 2021-10-04T23:09:57Z

Hi @kevinushey ,

Do you mean, use_condaenv ? I couldn't find, use_conda

This is what I get:

# reticulate::conda_list()
# reticulate::py_config()
# reticulate::install_miniconda()

library(reticulate)
use_condaenv("r-reticulate", required = TRUE)
system2("which","python", stdout = TRUE)
#> [1] "/usr/bin/python"
use_python("/usr/bin/python", required = TRUE)
py_config()
#> Error: Python shared library not found, Python bindings not loaded.
#> Use reticulate::install_miniconda() if you'd like to install a Miniconda Python environment.

@njtierney are you using the latest stable release of RStudio? If so, I think we are experiencing the same issue. When I run reticulate::py_config(), reticulate::py_available(), etc. from an R session in my terminal, I get the expected behavior. However, running this commands from within RStudio displays the same Error: Python shared library not found, Python bindings not loaded. you are experiencing. I suspect there is a configuration issue with the latest version of RStudio, but I can't for the life of me figure out what that is...

EDIT
reticulate::conda_list() displays local conda environments (even from with RStudio), however Global Options -> Python (select) -> Conda Environments displays no available environments.

njtierney · 2021-10-05T04:08:48Z

Hi Daniel, Yes - I'm using Ghost Orchid: ``` $mode [1] "desktop" $version [1] ‘2021.9.0.351’ $long_version [1] "2021.09.0+351" $release_name [1] "Ghost Orchid" ``` That would track with my experience actually, I'll try and use a previous version of RStudio and see how I go ...

I can confirm that reticulate works as expected with conda in RStudio Desktop 1.3.1093 but not in Rstudio Desktop 2021.09.0.

At this point, I am not sure if this issue should be transferred to the rstudio/rstudio repo or not.

njtierney · 2021-10-06T01:42:46Z

I think we should cross post this to rstudio/rstudio at least, this is a substantial bug

mgendarme · 2021-10-07T09:12:50Z

Hello,

I am experiencing similar issues in VSCode (version 1.60.2) so probably not only related to RStudio:

r$> reticulate::conda_list()
       name                                                python
1 Anaconda3            C:\\Users\\Myself\\Anaconda3\\python.exe
2       rtf C:\\Users\\Myself\\Anaconda3\\envs\\rtf\\python.exe
r$> reticulate::py_config()
Error: could not find a Python environment for C:/Users/Myself/Anaconda3/python.exe

Trying to set the anaconda environment using use_condaenv or setting python path with use_python doesn't help.

Also experiencing the issue as described by @njtierney, and on my end downgrading to RStudio Desktop 1.3.1093 like @d-bohn said did seem to unblock me from the issue. Unfortunately now stuck on a different topic around package install, but different topic, thank you for this thread, was helpful. Really hoping one day we get a re-design of reticulate, super useful but very buggy and hard to manage.

kevinushey · 2021-10-21T17:45:15Z

You might need to use Sys.unsetenv("RETICULATE_PYTHON") to unset an erroneously-set version of Python. See rstudio/rstudio#9952 for more details. Sorry for the trouble :-/

ries9112 · 2021-10-21T19:45:10Z

Thank you @kevinushey, I will keep playing around with this and try to get to the bottom of my issues. Really appreciate all your work, you are super awesome and sorry to sound negative there. I will come back to this comment and edit it if I find anything useful, but it seems like the specific issue discussed here got solved on my end by downgrading RStudio.
