Hi, I need help getting started with Owl. Any advice would be greatly appreciated!
I want to use owl generate a plot and write it to a png file on disk. I don’t want to use jupyter, and I am running on a server (Ubuntu 20.04) so no GUI. I installed
owl_plplot via opam. Here is my program:
open Owl open Owl_plplot let () = let file = "test.png" in let f x = Maths.sin x /. x in let h = Plot.create file in Plot.plot_fun ~h f 1. 15.; Plot.output h
and here is the output I am getting:
dune exec ./main.exe qt.qpa.xcb: could not connect to display qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb. Aborted
