At first, I chalked up my problems to being a novice Linux Mint user, but I was stumped at the same spot with pretty much the same messages after I ran install_greta_deps() on my Windows machine.
I installed and loaded greta and ran install_greta_deps() then restarted R. When I test greta [normal(0,1)] I get the message:
x Initialising python and checking dependencies, this may take a moment. … failed
Error: We have detected that you do not have the expected python packages setup.
You can set these up by running this R code in the console:
Then, restart R and run:
(Note: Your R session should not have initialised Tensorflow yet.)

I didn’t explicitly initialize Tensorflow and when I try to follow the second approach to setting up python/miniconda:
Error: Miniconda is already installed at path “C:/Users/degaspec/AppData/Local/r-miniconda”.
reticulate::install_miniconda(force = TRUE)to overwrite the previous installation.
I tried reticulate::install_miniconda(force=TRUE) which seemed to work, followed by:
reticulate::conda_create( envname = "greta-env", python_version = "3.7" ) reticulate::conda_install( envname = "greta-env", packages = c( "numpy==1.16.4", "tensorflow-probability==0.7.0", "tensorflow==1.14.0" ) ) ...but at the end of all that I got the message: Error: one or more Python packages failed to install [error code 1] Looking for a solution to getting greta up and running. Thanks! Curtis
