我正在使用PyPDF2库使用Python阅读PDF文件，但它抛出错误。这是我用来读取存储在运行脚本的同一文件夹中的PDF的代码：

def pdf_reader():
        book = open("spm.pdf","rb")
        pdfReader = PyPDF2.PdfFileReader(book)
        pages = pdfReader.numPages
        speak(f"Total number of pages in this book are {pages}")
        speak("Sir please enter the page number which you want me to read")
        pg = int(input("enter the page number here : "))
        page = pdfReader.getPage(pg)
        text = page.extractText()
        speak(text)

但它会抛出以下错误：
