Hello,

I’m trying to use the iminuit package from python. However, I do not know whether it is possible to get all the output from python. Here is some simple code in python:

```julia
from iminuit import Minuit
def f(a, b):
    return a **2 + b** 2

pymin = Minuit(f, a=1, b=1, pedantic=False, print_level = 1)
pymin.migrad()

```

The output is:

 ![pyoutput](https://global.discourse-cdn.com/julialang/original/3X/2/6/26d280d31164c87d33d5e11e9d68376c209cdc39.png)

The julia code:

```julia
minuit = pyimport(:iminuit)
f(a, b) = a^2 + b^2
pyfun = py"lambda fun: lambda a, b: fun(a, b)"
fmin = minuit.Minuit(pyfun(f); a=1, b=1,pedantic=false, print_level = 1)
fmin.migrad()

```

The output is much less:

How can I get the output like in python?

Thank you!

Isn’t this all the same stuff (just badly formatted)?

Indeed all values are obtained, but the “keys” are lost.

Try `pycall(fmin.migrad, PyObject)` to prevent PyCall from trying to convert the output to a native Julia tuple.
