When I run the profiling code from this example in VSCode with Julia 1.11, the flame graph is empty. With Julia 1.10 it displays the usual way.
function profile_test(n)
for i = 1:n
A = randn(100,100,20)
m = maximum(A)
Am = mapslices(sum, A; dims=2)
B = A[:,:,5]
Bsort = mapslices(sort, B; dims=1)
b = rand(100)
C = B.*b
end
end
# compilation
@profview profile_test(1)
# pure runtime
@profview profile_test(10)
I’m not sure it is only a VSCode problem because I have observed similar behaviors with ProfileCanvas.jl and ProfileSVG.jl.
