Hello,

I have code in python that I am trying to import in Julia. I do the following:

```julia
np = pyimport("numpy");
pyimport("numba").guvectorize;

```

and in a separate file have

```julia
py"""
@guvectorize(['void(float64[:], float64[:], uint32[:], float64[:])'], '(n),(nq)->(nq),(nq)')
def myfunction(...)

```

If I remove `@guvectorize` and run the file with the python code, it goes through, if I keep it, I get  
`NameError("name 'guvectorize' is not defined")`

Am I importing it in the wrong way? Any ideas?

Best,
