我目前正在尝试使用https://www.tensorflow.org/guide/upgrade中提供的 jupyter notebook升级脚本以与tensorflow2兼容，以便我可以在 google colab 中运行它，但是当我运行时此单元格（来自 Windows 中的 Anaconda 环境）：

!tf_upgrade_v2 \
  --infile D:/Multiclass.py\
  --outfile /tmp/upgraded_Multiclass_CNN_V01_31012020Copy.py

我收到一个编码错误：

 Traceback (most recent call last):
  File "d:\programdata\miniconda3\envs\env_dlexp1\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)

    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 14: character maps to <undefined>

我通常会utf-8通过这样做将编码更改为： open(path, mode, encoding='UTF8') ，但在这种情况下我一无所知。我不是程序员，所以我的能力非常有限。请帮助我理解这个错误。

尝试在 ast_edits.pywith open中函数的第 918 行编辑process_file并指定 encoding='utf-8'，以便在函数process_opened_file中可以使用 utf-8 读取文件。
