无法获取页数 poppler 是否已安装并在 PATH 中？

如何解决无法获取页数 poppler 是否已安装并在 PATH 中？

我一直在尝试执行这部分代码，但错误不断弹出。我已经将 poppler 添加到 evn 路径中。还有什么我可以做的吗？

代码：

!pip install pdf2image
!pip install opencv-python
!pip install PILLOW
!pip install PyTesseract
!pip install poppler-utils

from pdf2image import convert_from_path
import cv2
from PIL import Image
import PyTesseract

from pdf2image import convert_from_bytes 
pdfs = r"C:\Users\sreeh\OneDrive\Desktop\OCR\Invoice/pdf"
# (Above statements executed well)

pages = convert_from_path('Invoice.pdf',350)

Error after execution of thia statement:-
