Python fitz 'Document' object has no attribute 'convertToPDF'-526互联

最近在自学python 有个png转PDF的需求，然后网站找了下。

def png2pdf(name):
        imgdoc = fitz.open(name)
        pdfbytes = imgdoc.convertToPDF()    # 使用图片创建单页的 PDF
        imgpdf = fitz.open("pdf", pdfbytes)
        imgpdf.save(name[:-4] + '.pdf')

运行提示 'Document' object has no attribute 'convertToPDF'
然后查了下源码

我自己理解的意思是convertToPDF是老版本的方法，新版本下应该用 convert_to_pdf
运行下，解决
