Or, alternatively, how can i write - without this package where i have an error - to file x an array similar to this one?

x = [[1,2,3];[4,5,6]]

Thanks for help.

orialb · March 5, 2020, 9:29am

I have no clue about this specific error (although at some point it says Please run Pkg.build("CMake"), did you try that?), but there is also JLD2.jl maybe try installing that package.

No, i do it now, and i get errors again:

Ah, the good times of commodore 64, come on, and you’ve got everything inside …

Ohhhh (stupid i am!) this was added OK !
Many thanks!
So, was an old package …

I am not sure what is the status of JLD.jl (I use only JLD2), but it seems that the problem you encountered with it is related to an issue in BinaryProvider https://github.com/JuliaPackaging/BinaryProvider.jl/issues/149.

JLD2 works fine (i save and load my arrays and dictionarys), i have used it now.
Instead of compute some indexes every time, i save them after generating them, and reloading them the following times, with result of search time halved. Very good!
