Here is an error I encountered while trying the optimize:

Thank you.

Hello, I was following the steps detailed per https://swolfpy.readthedocs.io/en/latest/installation.html on my Macbook Pro (macOS Monterey 12.6.3).

Everything was fine until I tried to run swolfpy in python:

import swolfpy as sp
sp.swolfpy()

Which produced the attached error response. Not sure if this is a bug or something going wrong on my end? All help or suggestions appreciated!

Hi, I was trying to follow along with the case study example ([https://github.com/SwolfPy-Project/CaseStudy-JIE2021/blob/main/Base%20Case/Base_Case.ipynb]) to try and better understand the model and am encountering a KeyError when trying to create the project - full .md export attached.

Could you help me understand what/why this error is being thrown and how I can fix it? Thank you!

Hello,
I am trying to install miniconda but i am getting the following error: " destination folder contains special character ...". Could you please help?

I was able to get the program to run in my conda environment on windows. However, I'm having a bit of trouble on mac. I was able to succesfully configure my conda environment, install swolfpy with pip, and then launch python. However, when import swolfpy, I receive the following error:
>>> import swolfpy as sp
Traceback (most recent call last):

return self.unpack(pickle.load(open(self.filepath, "rb")))
ValueError: unsupported pickle protocol: 5

I then tried to configure another conda environment using python 3.9, this seems to have gotten a bit farther but after entering sp.swoflpy() the application starts a python application that isn't visible and I have the following warning:
>>> import swolfpy
>>> swolfpy.swolfpy()
qt.qpa.fonts: Populating font family aliases took 737 ms. Replace uses of missing font family "MS Shell Dlg 2" with one hat exists to avoid this cost.

I'm a bit of a conda and mac os rookie so any troubleshooting tips would be helpful. Also curious to know if anybody has gotten this to work on mac or if anyone has seen this error. This could be user error, but figured I'd ask for help.

Hello,

I am having this issue,

This is the image of installed packages:

I can provide additional information if needed,

Thank you.
