encoding - 运行 Tensorflow2 升级脚本触发编码错误

Question

我目前正在尝试升级脚本以兼容 tensorflow 2 通过使用 https://www.tensorflow.org/guide/upgrade 中提供的 jupyter notebook ，以便我可以在 google colab 中运行它，但是当我运行这个单元时(从 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)
  File "d:\programdata\miniconda3\envs\env_dlexp1\lib\runpy.py", line 85, in _run_code
    exec(code, run_globals)

    lines = in_file.readlines()
  File "d:\programdata\miniconda3\envs\env_dlexp1\lib\encodings\cp1252.py", line 23, in decode
    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>

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

Answer 1

尝试编辑 with open在函数的第 918 行 process_file在 ast_edits.py 中指定 encoding='utf-8'，以便在函数 process_opened_file 中该文件可以用 utf-8 读取。
