here i would like to use python as programing language to program interface which can help to control cold room remotely. my interest to use DHT11 sensor as in put and proting its real time deta on graph . this push is me to install some python modules or libraries like

 matplotlib,numpy and pandas

installation of python libraries

1. installation of matplotlib
2. 
3. installation of numpy and pands libraris

challenge faced after installing the python libraries
1. I tried to use vs-code as python ide but some code are runing and others are not runing
   

   
   
   Here i was complete to insatall all python libraries still the problem is the same.
2. I tried to solve the problem with creating virtual environment where you can access all library globaly in pc
   

   Whenever i tried to create virtual environment in comnd promt (cmd). I feiled to create this environment. due to this i decide to shift to other aproach of controlling the sound of busser on my dev board.
Interface and applicatioin with python tiknter
tiknter :is the de facto way in Python to create Graphical User interfaces (GUIs) and is included in all standard Python Distributions. In fact, it's the only framework built into the Python standard library.
bello this code i used to provide my interface to control the sound of busser on my board
import serial
  import tkinter as tk
  
  serialPort = 'COM8' # change this to match your Arduino serial port
  serialBaud = 9600
  
  def sendChar(char):
      ser = serial.Serial(serialPort  serialBaud)
      ser.write(char.encode())
      ser.close()
  
  root = tk.Tk()
  root.title("CONTROL BUZZER WITH TKINTER UI AND ESP32")
  
  buttonOn = tk.Button(root, text="Turn On", command=lambda: sendChar('H'))
  buttonOn.pack()
  
  buttonOff = tk.Button(root, text="Turn Off", command=lambda: sendChar('L'))
  buttonOff.pack()
  
  root.mainloop()
  
interface visiualiation

Arduino code to read searial pot and send the code on my mcu esp32 for interation between my UI and development board
const int buzzerPin  = 25;
  int incomingByte;      // a variable to read incoming serial data into
  
  void setup() {git 
    // initialize serial communication:
    Serial.begin(9600);
    // initialize the LED pin as an output:
    pinMode(buzzerPin , OUTPUT);
  }
  
  void loop() {
    // see if there's incoming serial data:
    if (Serial.available() > 0) {
      // read the oldest byte in the serial buffer:
      incomingByte = Serial.read();
      // if it's a capital H (ASCII 72), turn on the LED:
      if (incomingByte == 'H') {
         digitalWrite(buzzerPin, HIGH);
      }
      // if it's an L (ASCII 76) turn off the LED:
      if (incomingByte == 'L') {
          digitalWrite(buzzerPin, LOW);
      }
    }
  }
