1 download python

https://www.python.org/downloads/macos/

2 check installed python version

2.1 in python code

Code

import sys
print(sys.version)

3.11.4 (v3.11.4:d2340ef257, Jun  6 2023, 19:15:51) [Clang 13.0.0 (clang-1300.0.29.30)]

2.2 in r code

Code

reticulate::py_config()

python:         /Library/Frameworks/Python.framework/Versions/3.11/bin/python3
libpython:      /Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/config-3.11-darwin/libpython3.11.dylib
pythonhome:     /Library/Frameworks/Python.framework/Versions/3.11:/Library/Frameworks/Python.framework/Versions/3.11
version:        3.11.4 (v3.11.4:d2340ef257, Jun  6 2023, 19:15:51) [Clang 13.0.0 (clang-1300.0.29.30)]
numpy:          /Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/numpy
numpy_version:  1.26.0

NOTE: Python version was forced by RETICULATE_PYTHON

Code

reticulate::repl_python()

exit

it may using version 3.9.18 under miniconda

2.3 in terminal

Code

jinchaoduan@Jinchaos-MacBook-Air ~ % python3
Python 3.11.4 (v3.11.4:d2340ef257, Jun  6 2023, 19:15:51) [Clang 13.0.0 (clang-1300.0.29.30)] on darwin

Then we find the python path in terminal

Code

jinchaoduan@Jinchaos-MacBook-Air ~ % which python3
/Library/Frameworks/Python.framework/Versions/3.11/bin/python3
>>>

3 config which python we use in rstudio

create .Renviron file containing the line RETICULATE_PYTHON=“xxxx/python3” in home directory

Code

touch $HOME/.Renviron

Code

open $HOME/.Renviron

put RETICULATE_PYTHON=“/Library/Frameworks/Python.framework/Versions/3.11/bin/python3”
