pdfium library is not working when compiling my code in python

Question

I wrote a program in the python programming language that converts a pdf file to a jpg file. I used the "eel" library in the frontend part. Everything is working in VS Code. I used pdfium library to convert PDF to jpg file. I compiled the application code using pyinstaller. There is a problem with the pdfium library before launch.

Everything is working in VS Code. When I flash the EXE with pyinstallaer, I get an error saying that the "pdfium" library was not found.
