I’m new to Processing (and have limited experience with Python in general).

I’m trying to run my Python script and I’m getting this error message in the console:

Hmm. Can’t load native code to bring window to front using the absolute path: /Users/jenniferalmarine/Documents/Processing/modes/PythonMode/mode/libjniosx.dylib.  
Hmm. Can’t load native code to bring window to front.

I moved my Python folder from Documents to a folder on my hard drive because Documents syncs with my iCloud account. When I first downloaded Processing and was going through a tutorial, it wouldn’t run a script and I read online that the syncing could be the issue so I moved it but now I’m getting this error.

macOS Big Sur (11.6)  
Processing 3.5.4 (I’ve also tried Processing 4)

Edit: I tried finding my answer online. I found [this thread](https://forum.processing.org/two/discussion/20689/python-3-code-not-running-in-processing-3-2-4-on-mac-os-10-12-3) but there doesn’t seem to be a resolution.

Welcome Jennifer!

Sorry to hear it’s not working. I have never seen a message like yours.

Can you run some sample/test code like this:

```python
def setup():
    size(400, 400)
    rect(10, 10, 100, 100)

```

it should produce something like this:

I didn’t understand the part about moving your Python folder… I suppose moving the Python mode folder will break it. Could you try removing and re-installing the Python mode from the IDE (the Processing Editor)?

You can save your projects, called sketches, outside the Documents folder. A Processing project is always a folder with the same name as the main sketch file. In Python mode usually something like a folder called `sketch_21NNN` and a file called `sketch_21NNN.pyde` inside.

I have the same issue. I cannot run any sketch even the example given villares. Has anyone got the solution?  
I’m using macOS 12.3.1 and Processing 4.0b8 (Python mode).

I have tried removing and reinstalling processing and python mode - no results.

Welcome @pavel

Is this something that works in Processing 3.5.4? Or is it just Processing 4 beta that seems to have trouble?

I tried 3.5.4 and it worked without any issues. Thank you, @tabreturn! I think I’m going to stick to this version.

But I also found the fault with 4.0b8 - its P3D render. If I change it to default, 4.0b8 works too (with the exception that it will create a new sketch window every time I click “run” without closing the old one). Although, it does not explain why I could not run a simple sketch before…
