Need to reinstall reticulate whenever I want to access arcpy about reticulate HOT 4 OPEN

Thanks for opening. I haven't seen this error before.

My best guess is that reinstalling is forcing some dll's to be reloaded, which is fixing the error.

If you set PATH or any other envvar after initializing Python, the Python session will not see those env vars. You would need to independently also set in Python with import("os")$environ$update(...), or call R's Sys.setenv() before initializing Python.

Does swapping the order of your initialization commands fix the issue?

@t-kalinowski ,
Thank you for getting back.

If I understand correctly, you are saying to do this:

reticulate::use_python('C://ArcGIS//Pro//bin//Python//envs//arcgispro-py3/python.exe',required = T) #set python
Sys.setenv(PATH = paste("C://ArcGIS//Pro/bin", Sys.getenv("PATH"), sep = ";")) #manually ensure variables are loaded correctly
library(reticulate)
sa=reticulate::import("arcpy.sa") #try to load spatial analyst

if that is the case, then no, the issue persists after rearranging my order of operations.

from reticulate.

I'm sugesting something different actually:

# make sure you're in a fresh R session.
# in RStudio IDE: rstudioapi::restartSession(clean = TRUE)

library(reticulate)

# set env vars before initializing Python
Sys.setenv(PATH = sprintf("%s;%s", normalizePath("C:/ArcGIS/Pro/bin"), Sys.getenv("PATH"))

# initialize Python
use_python('C:/ArcGIS/Pro/bin/Python/envs/arcgispro-py3/python.exe')

# Confirm the correct Python was initialized
py_config() 

# import desired module
sa <- reticulate::import("arcpy.sa")

@t-kalinowski thank you for the clarification.

The order of operations that you have written worked for me-- there was no error. I did not know about the order of operations for reticulate.

I appreciate your quick response on this matter!
