ModuleNotFoundError: No module named '_dlib_pybind11' for face recognition

Question

I tried this code but was getting the error:

import cv2
import numpy as np
import face_recognition

imgEme = face_recognition.load_image_file('Image/Emeka1.jpg')
imgEme = cv2.cvtColor(imgEme,cv2.COLOR_BGR2RGB)
imgTest = face_recognition.load_image_file('Image/Emeka2.jpg')
imgTest = cv2.cvtColor(imgEme,cv2.COLOR_BGR2RGB)

cv2.imgShow('Chukwuemeka',imgEme)
cv2.imgShow('Chukwuemeka Test',imgTest)
cv2.waitKey(0)

Error message:

Traceback (most recent call last):
  File "c:\New-face-reg\new-face-reg.py", line 3, in <module>
    import face_recognition
  File "C:\New-face-reg\.venv\Lib\site-packages\face_recognition\__init__.py", line 7, in <module>

    from _dlib_pybind11 import *
ModuleNotFoundError: No module named '_dlib_pybind11'

I have installed cmake and dlib (dlib-19.24.1.dist-info), please what is the problem?
