Getting the below error when I run the code:

with open('C:\Users\My Folder\Downloads\RAG for LLMs.pdf', 'rb') as file:
    # Create a PDF reader object
    reader = PyPDF2.PdfFileReader(file)
    # Get the number of pages in the PDF file
    num_pages = reader.getNumPages()

FileNotFoundError: [Errno 2] No such file or directory: ‘C:UsersMy FolderDownloadsRAG for LLMs.pdf’

How to address this error.
