Multiple local imports

[Doublelucker]

Hello!

I have a very, I think, specific issue and I would like to know, why PyCall does that and how to fix it.

Let's assume, that I have 2 folders folder1 and folder2 which are repositories written in python and each has a main script file main1.py and main2.py, and those two just have inside them multiple local imports and a function main.

Then I have two julia scripts folder1.jl and folder2.jl, which call those main functions from those two folders. The code for folder1.jl goes like this:

 pushfirst!(PyVector(pyimport("sys")."path"), folder1)
 execute_JL = pyimport("main1")
 pyimport("importlib").reload(execute_JL)[:main](args)

And both julia scripts work fine. Now I want to combine them and call both scripts in the third script combine.jl.

This no longer works and here are two things that happen.

1. If the first element of PyVector(pyimport("sys")."path") is folder1, then I can import main1, if it's folder2, then no. But that I managed to fix this by just removing the folder from the path, once I ran the script.
2. If I do pyimport("main1"), I then cannot do pyimport("main2") and the opposite.

In both of these cases the first time you run the code the error doesn't even say anything - just that PyObject(Ptr{PyCall.PyObject_struct} @0x00000000521c49f0), PyObject(Ptr{PyCall.PyObject_struct} @0x00000000650bf2e8), PyObject(Ptr{PyCall.PyObject_struct} @0x00000000650b58c8)), for example. The second time you run it - all the local imports in the file that cannot be imported fail.

Can someone tell me why that happens?

P.S. As a workaround, I could probably create setup.py files in those folders and install them like python libraries, but I still wonder why right now I can't make this work.
