python environment mysteriously loads by itself?

The title of this post summarizes the issue. I am slighty confused why Python loads without my explicit permission.

I am working on a MATLAB project where startup file contains a line that loads Python using pyenv.

If I wait a few minutes between opening MATLAB and starting the project, I get the "Python is loaded" error message, even though I haven't yet loaded it:

Warning: Error using pyenv
Python is loaded. The environment cannot be changed in this MATLAB session. To change the environment, restart MATLAB, and then call 'pyenv'.

I understand my question might be a bit vague and I would be glad to provide more details as needed... I'm not quite sure where to go from here

Hello,

What do you mean "startup file" for your project? Which file and what dose it include?

Hi, the startup file is an .m script that executes as soon as you open a saved project. In my case, I set up global variables, set a python environment and then load python

is the file name startup.m ?

[dleal]

no. I called it initPython.m

I attached a sample file, it wont run, but at least you can see how I am invoking Python... the only thing I can think might cause an issue is that I am loading an Anaconda environment and maybe MATLAB loads it by itself
