Here is what I have in my shiny app
library(shiny)
library(shinyWidgets)
library(tidyverse)
library(reticulate)
library(DT)
library(data.table)
virtualenv_create(envname = "python_environment", python= "python3")
virtualenv_install("python_environment", packages =c('pandas','catboost'))
use_virtualenv("python_environment",required = TRUE)
I have created an init.R and run.R file to run the app and install all dependencies in my home directory and my app is located in ml model >> app/boxing
