Do nested tables lose values if you send them into a data store

[ew_iscool (professional)]

im making a saving system to save neural networks, and they have their layers, neurons, biases, connections, etc, saved inside of nested tables inside of nested tables.

i’ve written 2 scripts that save and load the neural networks, and they SEEM to have nothing wrong with them. the issue is, what gets loaded is not what i saved, so its either saving didnt save everything, or loading did load everything.

SAVING SCRIPT:

local datastoreService = game:GetService("DataStoreService")
local NetworkSave = datastoreService:GetDataStore("Network")

print(NetworkSave:GetAsync("Network"))

local BestNetwork = require(game.ServerScriptService.BestNetwork)

script.Parent.MouseButton1Click:Connect(function()
	print(BestNetwork.BestNetwork)
	NetworkSave:SetAsync("Network",BestNetwork.BestNetwork)
end)

LOADING SCRIPT:

local datastoreService = game:GetService("DataStoreService")
local NetworkSave = datastoreService:GetDataStore("Network")

local BestNetwork = require(game.ServerScriptService.BestNetwork)

script.Parent.MouseButton1Click:Connect(function()
	local NewNetwork = NetworkSave:GetAsync("Network")
	BestNetwork.BestNetwork = NewNetwork
	
	print(NewNetwork)
	
	game.ServerScriptService.TeachingScript.Enabled = false
	wait(0.5)
	game.ServerScriptService.TeachingScript.Enabled = true
end)

The only way that I know of that you’ll lose information when saving data is if the table or any of the nested tables is a mixed table. In that case, I believe the string keys will be dropped from that table when saving to the data store.

I’d double check that that isn’t the case with your tables.

this is exactly what happened, are there any workarounds?

I think u should use datastore2 if u need to use strings

Either convert all your numeric keys to string keys right as you’re about to save the table or structure your tables to avoid mixed tables altogether.

I recommend the latter. Unless the table you’re trying to save is super complex, it shouldn’t be too difficult to restructure it.
