attempt to apply non-function

[Feifei0511]

I want to install ivis in R, but show the error as the title. The system of my computer is Windows, so I have installed conda before running the code., can anyone help me to solve this problem. thank you! library (reticulate) devtools : : install _github("beringresearch/ivis/R-package") library (ivis) model ＜- ivis (k ＝ 3） Error in ivis _object$Ivis(embedding _dims ＝ embedding _dims, k ＝ k, distance ＝ distance, : attempt to apply non-function

Hi there!

Before running ivis, if you're installing it for the first time you need to call install_ivis() in R:

devtools::install_github("beringresearch/ivis/R-package")
library(ivis)
install_ivis()

That will install all the python requirements - let us know if that helps

Thanks for your answer! I have called install _ivis() in R in the first time, but there was an error --Error: one or more Python packages failed to install [error code 1] And I tried to run "pip install ivis ”, but not succeed. I don't know where is wrong, So how do I solve it?

[idroz]

Hi - Could you provide more details on that error pls - i.e. which python package is failing to install?

Probably has something to do with dependencies - are you installing under WSL?

[Feifei0511]

Hi! This is the detail on that error, I never tried to install under WSL, and I don't how to run in WSL. Could you give me some suggestions?

Error: one or more Python packages failed to install [error code 1]

Thanks for bringing this up, the R-package on Windows hasn't been something we use much and developed a few issues. I've pushed a series of commits to the master branch that should hopefully fix the issues you are having if you reinstall ivis.

Hi , thanks for your helping. I tried to reinstall ivis recently, but there was a new error when I run "install _ivis()". I can't understand this error, could you help me to solve this problem?

＞install _ivis() raise ReadTimeoutError(self._pool, None, "Read timed out.") pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.

This looks to me like an internet connection error. I can’t reproduce it unfortunately.

[Feifei0511]

Thanks for your helping, I don't solve it successfully. I try to use other methods in Rstudio. Thanks for your answer., thank you!

[idroz]

Could you check to see if you can install from command line? I remember seeing that RStudio can have weird proxy settings preventing download from repo with a connection time out error.
