[Python] asp.net c# webform passing parameters to a python script not running

I found an example of how to pass parameters using PythonNet, but I am not able to get it to trigger my Python code. Developing on VS 2022. I'm wanting to (first) create a subdirectory if is doesn't already exist. The path and directory should be passed from C#.

protected void btnPythonTest_Click(object sender, EventArgs e)
{
// full path of python interpreter
string python = @"C:\Users\User\AppData\Local\Programs\Python\Python312\python.exe";

// python app to call
string myPythonApp = @"C:\OllamaDocs\MyTestPython.py";

// Paramters to send to Python (location of docs and Chroma for this user
string OllamDocsPath = @"C:\OllamaDocs\100\1\";
string OllamaChromaFilename = "Chroma_100_1B";

try
{
System.Diagnostics.ProcessStartInfo myProcessStart = new System.Diagnostics.ProcessStartInfo(python);
myProcessStart.UseShellExecute = true;
myProcessStart.RedirectStandardOutput = false;

// pass arguments to python script
myProcessStart.Arguments = myPythonApp + " " + OllamDocsPath + " " + OllamaChromaFilename;

System.Diagnostics.Process myProcess = new System.Diagnostics.Process();

myProcess.StartInfo = myProcessStart;

myProcess.Start();

lblStatus.Text = myPythonApp + " Created " + OllamDocsPath + OllamaChromaFilename;

}
catch (Exception ex)
{
errorMessage = ex.Message;
lblStatus.Text = errorMessage;

}

} // end PythonTest()


My Python test script is located in the root of C: as follows (MyTestPython.py)

import os import sys

# Test Phase II

#Get args from C#
OllamaPath = sys.argv[0]
OllamaChroma = sys.argv[1]

# Define the directory for vector store persistence
#persist_directory = "C:\\OllamaDocs\\100\\1\\chroma_db_100-1"
persist_directory = OllamaPath

# Check if the vector store already exists
if not os.path.exists(persist_directory):
print("Creating new Chroma Directory " + persist_directory)
os.makedirs(persist_directory) else:
# Load the existing Chroma vector store
else:
# Load the existing Chroma vector store
print("path exists.")
