Я пытаюсь создать файл PDF с помощью pyfpdf в Python Django. следующий фрагмент кода я пытаюсь создать PDF-код HTML. 

    from fpdf import FPDF, HTMLMixin
    class WriteHtmlPDF(FPDF, HTMLMixin):
        pass

    html = f"""<h3>xxxxx</h3>
 <div style="border:1px solid #000">
     <table border="1" cellpadding="5" cellspacing="0" width="100%">
         <tr><th width=20 align="left">xxxxxxxx:</th><td>xxxxxxxx</td></tr>
         <tr><th width=20 align="left">xxxxxxxx:</th><td>xxxxxxxxx</td></tr>
         <tr><th width=20 align="left">xxxxxxxx:</th><td>xxxxxxxxx</td></tr>
         <tr><th width=20 align="left">xxxxxxxx:</th><td>xxxxxxxxx</td></tr>
     </table>
 </div>
 <div>
     <table border="1" cellpadding="5" cellspacing="0" align="center" width=100>
         <tr>
             <td width=33>xxxxxx: 1</td>
             <td width=33>xxxxxx: 0</td>
             <td width=33>xxxxxx: 1</td>
         </tr>
     </table>
 </div>
 <table style="border: 1px solid black;" border="1" cellpadding="5" cellspacing="0" width=100>
     <thead align="center">
         <tr style="background-color: #6AB9F7;">
             <th>Sr No.</th>
             <th>Name</th>
             <th>xxxxx</th>

             <th>xxxxx</th>

     </thead>

Я использую несколько таблиц в своем HTML-коде и сталкиваюсь с проблемой при создании PDF. Следующее - ошибка, которую я получаю. 

     Traceback (most recent call last):

Я пробовал GitHub решения, но все равно получаю ту же ошибку

Похоже, WriteHtmlPDF() не нравятся теги <thead></thead> и <tbody></body>.

Небольшое исправление: 

from fpdf import FPDF, HTMLMixin
import os

class WriteHtmlPDF(FPDF, HTMLMixin):
    pass

pdf = WriteHtmlPDF()
# First page
pdf.add_page()

html = f"""<h3>xxxxx</h3>
 <div style="border:1px solid #000">
     <table border="1" cellpadding="5" cellspacing="0">

         <tr><th width=20 align="left">xxxxxxxx:</th><td width="100">xxxxxxxxx</td></tr>
         <tr><th width=20 align="left">xxxxxxxx:</th><td width="100">xxxxxxxxx</td></tr>
