Python shared library not found, Python bindings not loaded. in RStudio on Mac

Question

I have seen this question answered for issues in Windows but haven't seen any solution for a Mac.

After installing keras like:

devtools::install_github("rstudio/keras")
library(keras)
install_keras()

I get the error when running:

library(keras)
mnist <- dataset_mnist()

>> Error in initialize_python(required_module, use_environment) : 
  Python shared library not found, Python bindings not loaded.

I have tried the following:

use_python("/Users/me/anaconda3/bin/python3.7", required = TRUE)
use_virtualenv("~/MyFolder/.venv/")
use_python("~/MyFolder/.venv/bin/python")

But haven't been successful, I saw some suggestions about wrong python installation but it shouldn't be it in my case. i have installed python 3.7.5 with Anaconda

=> python --version
Python 3.7.5

I'm on macOS Catalina Version 10.15.1 in RStudio, Version 1.2.5019. Does anyone have any solution?

Answer 1

This is a old thread, but just wanted to say for anyone that finds this that installing the python-dev package for whatever version of python you're using may work. I was using python3.8, so I installed python3.8-dev

Answer 2

I had same problem with OSX. Found solution by configuring python virtual environment to use python3

library(reticulate)
use_python("/usr/local/bin/python3")
