check_tf_version works

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:
`install_greta_deps()`
Then, restart R and run:
`library(greta)`

define and mcmc error informatively

none of the <greta_array>s in the model are associated with a probability density, so a model cannot be defined

none of the <greta_array>s in the model are associated with a probability density, so a model cannot be defined

could not find any non-data <greta_array>s

model contains a discrete random variable that doesn't have a fixed value, so inference cannot be carried out

none of the <greta_array>s in the model are unknown, so a model cannot be defined

data <greta_array>s cannot be sampled
`x` is a data <greta_array>(s)

check_dims errors informatively

incompatible dimensions: 3x3, 2x2

disjoint graphs are checked

the model contains 2 disjoint graphs
one or more of these sub-graphs does not contain any <greta_array>s that are associated with a probability density, so a model cannot be defined
