Unable to install keras/tf after R update on MacOS 10.14

[matthiasmace]

Hi,
After running perfectly TF 1.1/Keras, I tried to update.
I am now unable to install Keras.

>devtools::install_github("rstudio/keras")
> library(keras)
> install_keras()
Using virtual environment '/Users/matthias/.virtualenvs/r-reticulate' ...
Traceback (most recent call last):

I am having the same problem. Keras / TF was working, but I needed to get an update to get some new features. I'm running MacOS 10.15.1, and I got the following. I hope someone fixes this.

devtools::install_github("rstudio/tensorflow")
Downloading GitHub repo rstudio/tensorflow@master
These packages have more recent versions available.
Which would you like to update?

1: All
2: CRAN packages only
3: None
4: jsonlite (1.5 -> 1.6 ) [CRAN]
5: reticulate (1.10 -> 1.14 ) [CRAN]
6: rstudioapi (0.7 -> 0.10 ) [CRAN]
7: R6 (2.2.2 -> 2.4.1) [CRAN]
8: Rcpp (1.0.0 -> 1.0.3) [CRAN]
9: whisker (0.3-2 -> 0.4 ) [CRAN]
10: glue (1.3.0 -> 1.3.1) [CRAN]

Enter one or more numbers, or an empty line to skip updates:

Hello,

The code that installs tensorflow and keras has been refactored.
Please update to the latest versions of reticulate, tensorflow, and keras:

install.packages("remotes")
remotes::install_github(paste0("rstudio/", c("reticulate", "tensorflow", "keras")))
reticulate::install_miniconda() # skip this if you want to self-install conda or use venv
keras::install_keras()

Please let us know if after updating you are still encountering installation issues:
