While trying to use [SimpleHypergraphs.jl](https://github.com/pszufe/SimpleHypergraphs.jl) visualization tools which require hypernetx (a python library), I encountered an error while running the following (which comes from the README of [SimpleHypergraphs.jl](https://github.com/pszufe/SimpleHypergraphs.jl) ):

```julia
using PyCall
using Conda
Conda.runconda(`install matplotlib --yes`)
Conda.runconda(`install networkx --yes`)
Conda.runconda(`install pandas --yes`)
run(`$(PyCall.python) -m pip install hypernetx`)
pyimport("hypernetx")

> ERROR: PyError (PyImport_ImportModule
> The Python package hypernetx could not be imported by pyimport. Usually, this means
> that you did not install hypernetx in the Python version being used by PyCall.[...]

```

Similarly doing `using SimpleHypergraphs` gives me the following warning  
`┌ Warning: The plotting functionality of HyperNetX will not work! │ Conda Python HyperNetX not found.`

The package is in my Conda environment and in my python environment (verified by running `Conda.list()` and `run(`$(PyCall.python) -m pip list`)` respectively in the same Julia session).

Am I doing something wrong? If so, what am I supposed to do?

```julia
julia> versioninfo()
Julia Version 1.7.1

fwiw, using [PythonCall.jl](https://github.com/cjdoris/PythonCall.jl)/[CondaPkg.jl](https://github.com/cjdoris/CondaPkg.jl) seems to work well:

```julia
pkg> activate .

(hypernetx) pkg> add CondaPkg

julia> using CondaPkg

(hypernetx) pkg> conda add matplotlib networkx pandas decorator

(hypernetx) pkg> conda pip_add hypernetx

(hypernetx) pkg> conda st
CondaPkg Status /home/mango/Projects/hypernetx/CondaPkg.toml
Packages
  decorator v5.1.1
  matplotlib v3.5.2
  networkx v2.8.3
  pandas v1.4.2
Pip packages
  hypernetx v1.2.4

(hypernetx) pkg> add PythonCall

julia> using PythonCall

julia> @py import hypernetx as hnx

julia> hnx
Python module: <module 'hypernetx' from '/home/mango/Projects/hypernetx/.CondaPkg/env/lib/python3.10/site-packages/hypernetx/ __init__.py'>

```

Just a quick note that I included the `decorators` package because it seemed to be required for the installation to work, same when trying in a plain python shell

I’m not able to reproduce this on linux, so this might be a windows specific issue?

The missing dependency on “decorator” was the problem!

Thank you!

I’ll open an issue on [SimpleHypergraphs.jl](https://github.com/pszufe/SimpleHypergraphs.jl) to add it in the README
