Hi everyone,

I am writing a small package for a personel project. It is dependant on a python package that is wrapping another code written in Fortran.

I know how to install it via pip in PyCall.jl and it works great. But I would like to have a setup to install it automatically if someone download my package. I am not that experienced in Julia but I’ve read a bit about the \_\_ init \_\_ function that I could maybe put in my main module containing the code to install the python package.

Let’s say I want to install numpy as an example:

```julia
using PyCall
run(`$(PyCall.python) -m pip install --upgrade numpy`)

```

Would I just need to write this lines in the **init** function? What would be the best way to do it then?

By no means an expert here, but have you considered PythonCall.jl instead of PyCall.jl? I think it offers something like this

Indeed PythonCall offers a nicer way to manage dependencies (I would say that, I wrote it) but if you do want to use PyCall then `pyimport_conda` will install dependencies for you automatically when you import a package: [GitHub - JuliaPy/PyCall.jl: Package to call Python functions from the Julia language](https://github.com/JuliaPy/PyCall.jl#using-pycall-from-julia-modules)

Thank you both for nice options. The thing that prevented me a bit from using PythonCall (while knowing nothing about the differences btw the 2 packages) was that it is not yet in 1.x.x version but appart from that, the packages seem quite equivalent. And reading a bit the docs, PythonCall seems indeed better for what I want. Is there a particular reason why it is not considered as production ready or something I should be aware of?
