Can you see your erlang version when running Benchee.System.system(%Benchee.Suite{}) in livebook?

Post #1

Athunnea

From Livebook

%Benchee.Suite{
  system: %{
    erlang: :ok,

From console:

%Benchee.Suite{
  system: %{
    erlang: "25.2",

Seems to be an issue in this function then (which already has a comment about a workaround for livebook): benchee/lib/benchee/system.ex at main · bencheeorg/benchee · GitHub

What happens when you run :erlang.system_info(:otp_release) ?

> :erlang.system_info(:otp_release)
'25'

> System.build_info()
%{
  build: "1.14.2 (compiled with Erlang/OTP 25)",
  date: "2022-11-11T11:39:40Z",
  otp_release: "25",
  revision: "0909940",
  version: "1.14.2"
}

By the way, it’s a compiled Livebook App, i don’t know if it carries its own erlang/elixir or uses one from my system
