Could specify: python, engine.path = “C:/ProgramData/Anaconda3/envs/wk_pyfan/python.exe”, this is already set inside Rprofile: knitr::opts_chunk$set(engine.path = “C:/ProgramData/Anaconda3/envs/wk_pyfan/python.exe”)

Install reticulate from github directly to get latest version: devtools::install_github(“rstudio/reticulate”)
Check python version on computer:
Sys.which('python')
## python
## "C:\\PROGRA~3\\ANACON~1\\envs\\wk_pyfan\\python.exe"
After installing reticulate, load in the library: library(reticulate). With “py_config()” to see python config. First time, might generate “No non-system installation of Python could be found.” and ask if want to install Miniconda. Answer NO.
Correct outputs upon checking py_config():

Set which python to use:
# Sys.setenv(RETICULATE_PYTHON = "C:/programdata/Anaconda3/python.exe")
# Sys.setenv(RETICULATE_PYTHON = "C:/ProgramData/Anaconda3/envs/wk_pyfan/python.exe")
