Because of copyright restrictions, this program requies a legal copy of Sid Meier's Civilization IV, along with both expansion packs, Rise & Fall and Gathering Storm. These are required to perform some of the functions used in the program.
Next, make sure you have python 3.4+ installed, then please run pip install numpy keras
Finally, make sure that you have Lua 5.3 installed, no additional libraries required.
Before running the code, please replace the VikingScenario.lua file from the ...\Steam\steamapps\common\Sid Meier's Civilization VI\DLC\VikingsScenario\Scripts folder with the one in this repository.
Additionally, please copy and paste all the python files (and the models folder) into the ...\Steam\steamapps\common\Sid Meier's Civilization VI\Base\Binaries\Win64Steam folder (this name may be a bit different on Unix systems).
Assuming the above has been performed correctly, the test environment should be accessible from the Single Player > Scenarios option on the main menu.
Before running the code, we recommend a forced update of the game and its expansions to make sure the latest build has been installed and that there are no conflicting code blocks in the installed build.
If the lua code in the game is returning an error that you are trying to index a nil value on lines that reference the os or io libraries, this means the game needs to be run as administrator.
