問題描述
運行 Tensorflow2 升級腳本會觸發編碼錯誤 (Running the Tensorflow2 upgrade Script triggers an encoding error)
我目前正在嘗試使用 https://www.tensorflow.org/guide/upgrade，這樣我就可以在 google colab 中運行它，但是當我運行這個單元格時（來自 Windows 中的 Anaconda 環境） ：
!tf_upgrade_v2 \
‑‑infile D:/Multiclass.py\
‑‑outfile /tmp/upgraded_Multiclass_CNN_V01_31012020Copy.py
我得到一個編碼錯誤：
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>
我通常會通過這樣做將編碼更改為utf‑8 : open(path, mode, encoding='UTF8') ，但在這種情況下我一無所知。我不是程序員，所以我的能力非常有限。請幫助我理解這個錯誤。
參考解法
方法 1:
Try editing with open in line 918 of function process_file in ast_edits.py and specify encoding='utf‑8', so that in the function process_opened_file the file can be read with utf‑8.
