Python code execution through .net web application : getting error "No module named pyodbc"

I am trying to Execute python script from my .Net Web Application. For this I have installed Python from nuget package manager. But I am getting following errors during execution:

I have attempted following code chunks for getting resolution but I am not able to execute it successfully.

Below is the Python Scrip to Insert a record in SQL Server database:

import pyodbc
conn = pyodbc.connect('DRIVER={SQL Server Native Client 
11.0};SERVER=*****\SQLEXPRESS;DATABASE=TestDB;UID=sa;PWD=****')
cur = conn.cursor()
cur.execute("Insert into Results([EmailID],[Journey]) VALUES (?,?)", 55, 
"JourneyName") 
conn.commit()
Print("Success")  

Below is the C# Code to execute above python file.

public string run_cmd(string strPath) //this must not be async
{
    try
    {
       ProcessStartInfo start = new ProcessStartInfo();
       start.FileName = @"C:\Anaconda\python.exe";
       start.Arguments = string.Format("C:\\Users\\261866\\TestPYCode.py");
       start.UseShellExecute = false;
       start.CreateNoWindow = true; 
       start.RedirectStandardOutput = true;
       start.RedirectStandardError = true;
       using (Process process = Process.Start(start))
       {
           using (StreamReader reader = process.StandardOutput)
           {
               string stderr = process.StandardError.ReadToEnd();
               string result = reader.ReadToEnd(); 
               return result;
           }
        }
     }
        catch (Exception ex)
        {
            return ex.Message;
        }
            return "run till end";
    }

As I have executed above c# code I am getting below Error:

Traceback (most recent call last):"C:\Users\261866\TestPYCode.py" import pyodbc Module Not Found Error: No module named 'pyodbc'

Error: No module named 'pyodbc'
