python使用docxtpl处理word文档图片不显示问题

docxtpl的使用：

安装docxtpl：

pip install docxtpl

基本使用实例main.py：

from docxtpl import DocxTemplatedoc = DocxTemplate("my_word_template.docx")sd = doc.new_subdoc("my_subdoc.docx")context = {'company_name': "World company", 'sub_doc': sd, }doc.render(context)doc.save("generated_doc.docx")1

其中模板文件my_word_template.docx内容如下：

子文件my_subdoc.docx内容如下：

执行main.py生成generated_doc.docx文件

问题处理：
