> Yeah that’s tricky, you need to place the import in the init function, see how I did it here [https://github.com/baggepinnen/HDBSCAN.jl/blob/master/src/HDBSCAN.jl](https://github.com/baggepinnen/HDBSCAN.jl/blob/master/src/HDBSCAN.jl)

I tried doing this, but is not working:

```julia
    using ScikitLearn, PyCall
    const LogisticRegression = PyNULL()
    function __init__ ()
        @eval global LogisticRegression = pyimport("linear_model")
    end

```

Gives this error:

```julia
  Got exception outside of a @test
  LoadError: InitError: PyError (PyImport_ImportModule
  
  The Python package linear_model could not be found by pyimport. Usually this means
  that you did not install linear_model in the Python version being used by PyCall.

```
