Users are required to have Julia v. 1.0 or above installed. Julia can be downloaded from the official page at https://julialang.org/downloads/.
You can confirm your version number by typing VERSION into the Julia console or REPL, as shown in the following code snippet:
julia> VERSION
v"0.7.0-DEV.4465"
The Julia community does not keep sources other than the Julia website or GitHub up-to-date. Therefore, it is strongly advised to refer to the official website for the latest available version. For example, Ubuntu users get an older version when installing Julia using apt-get.
You should also clone or download a GitHub repository containing source code and sample images:
https://github.com/PacktPublishing/Hands-On-Computer-Vision-with-Julia
This can be done by going to the GitHub page and pressing either the Clone or Download button in the top right corner.
