Multiple assignment operator %<-%
In Listing 6.35 “Computing the common-sense baseline MAE” multiple assignment operator %<-% used, but library(keras) introduced only in Listing 6.37 “Training and evaluating a densely connected model”, so if you start from clean R environment, as I did, you will be got error, beside lack in documentation about this nice keras library feature.

Multiple assignment operator %&lt;-%
Thanks for pointing this out! I added a
library(keras)
call so that the example runs.

Note that we do actually have a callout note on the multi-assignment operator in section 3-5

Oh boy, it’s my fault, I was miss remark at section 3-5. I jumped to RNN section, straight after finished introduction.
