Can anyone give me an example of using Turing for sampling using metropolis hastings algorithm?

I have a normal proposal distribution with mean 3 and variance 4. Can anyone give me an example of sampling using metropolis hastings algorithm?

AdvancedMH.jl will do this, I think that you probably want

static_prop = StaticProposal(Normal(3,4))

see the README for more info.

say I want to sample using

sample(model,  MH, number of samples)

I have a posterior p(x) = 7 exp(-x/4) + 4 exp(-x/6) - 7*exp(-(x-4)^2/64)

I want to sample using sample function and the posterior. Can you give me an example?
