I was trying to install the [HiddenMarkovModels.jl](https://github.com/BenConnault/HiddenMarkovModels.jl) package, by copy pasting the command

```julia
julia> Pkg.add("HiddenMarkovModels")

```

But it throws the error

```julia
ERROR: The following package names could not be resolved:

I wonder if I am missing something obvious ? Any help would be much appreciated. Thank you.

The last commit on this package was 5 years ago, so pre 1.0.

Unfortunately this package is also too outdated to install on post 1.0 julia versions.

I see. Thanks,  
Do you know of any other Julia package for hidden Markov models, by any chance ?

HMMBase is nice :

> Hi, I’d like to introduce [HMMBase.jl](https://github.com/maxmouchet/HMMBase.jl). A package providing basic building blocks for hidden Markov models in Julia. Motivation While there are many implementations of HMMs for Julia, and other languages, I found out that: Julia packages, such as [HiddenMarkovModels.jl](https://github.com/BenConnault/HiddenMarkovModels.jl) were not maintained anymore and thus not compatible with recent Julia version. Most HMMs libraries tend to directly implement the algorithms for a given probability distribution, most commonly discrete and normal distributions, a…

HHMBase may have some problems with its documentation. I was just trying it out, and the key commands mentioned in the documentation, such as

```julia
    fit_mle(hmm, y, display = :iter)

```

and

```julia
z, y = rand(hmm, 500, seq = true)

```

generate errors.

For example

```julia
julia> z, y = rand(hmm, 500, seq = true);
ERROR: MethodError: no method matching rand(::HMM{Multivariate,Float64}, ::Int64; seq=true)
Closest candidates are:
  rand(::AbstractHMM, ::Int64; initial_state) at C:\Users\iamsu\.julia\packages\HMMBase\Sv6Fz\src\hmm.jl:95 got unsupported keyword argument "seq"
  rand(::Any, ::Integer, ::Integer...) at C:\buildbot\worker\package_win64\build\usr\share\julia\stdlib\v1.5\Random\src\Random.jl:283 got unsupported keyword argument "seq"
  rand(::Hypergeometric, ::Int64) at C:\Users\iamsu\.julia\packages\Distributions\dTXqn\src\common.jl:145 got unsupported keyword argument "seq"

```

and

ERROR: MethodError: no method matching fit_mle(::HMM{Multivariate,Float64}, ::Array{Float64,2}; display=:iter)

It works for me, fwiw, what version are you using?

And you are sure the following fails?

It works for me, maybe you have an old version of HMMBase ?

Mine : HMMBase v1.0.6, Distributions v0.23.12 (do `]st` to see it)

There’s also [HMMGradients](https://github.com/idiap/HMMGradients.jl) in case you want to train HMMs using gradient based techniques.

Btw, it’s really a shame these packages are not updated.  
Ben Connault had really amazing packages for estimating discrete choice models.  
Economists have nothing like this in any other language!  
(Only other thing is PyBLP.py)

Sometimes really good ppl leave academia for industry…
