错误出在您的模型中，请参见下文：

from django.utils.encoding import python_2_unicode_compatible
ImportError: cannot import name 'python_2_unicode_compatible' from 'django.utils.encoding' (C:UsersthatpAppDataLocalProgramsPythonPython38-32libsite-packagesdjangoutilsencoding.py

它只适用于 Django>=1.5，见这里：https://stackoverflow.com/a/20741848/9710734
