python - 处理文本时遇到字符编码问题

Question

我正在尝试处理大型语料库，但在 preprocess_string( ) 中它返回如下所示的错误

Traceback (most recent call last): File "D:/Projects/docs_handler/data_preprocessing.py", line 60, in <module> for temp in batch(iterator,1000): File "D:/Projects/docs_handler/data_preprocessing.py", line 30, in batch for item in iterable: File "D:/Projects/docs_handler/data_preprocessing.py", line 23, in iter_tokenized_documents document = preprocess_string(open(os.path.join(root, file)).read().strip(),filters=CUSTOM_FILTERS) File "C:\Users\koradg\AppData\Local\Programs\Python\Python36\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 0x9d in position 16144: character maps to <undefined>

如何运行而不出错？

Answer 1

从您的问题看来，您遇到了编码错误。只需在打开文件中使用 encoding='utf-8' 即可。如果该章程不重要，请在打开文件中使用此errors="ignore"。
