我尝试使用csv
模块在Python中加载CSV文件,遇到了带有以下错误消息的UnicodeDecodeError
:
from langchain.document_loaders.csv_loader import CSVLoader
loader = CSVLoader(file_path='/content/testing.csv' ,
source_column="prompt")
data = loader.load()
字符串
错误:FileNotFoundError Traceback(most recent call last)/usr/local/lib/python3.10/dist-packages/langchain/document_loaders/csv_loader.py in load(self)67 try:-> 68 with open(self.file_path,newline="",encoding=self.encoding)as csv file:69 docs = self.__read_file(csv file)
FileNotFoundError:[Errno 2] No such file or directory:'/content/testing.csv'
上述异常是以下异常的直接原因:
RuntimeError Traceback(most recent call last)1 frames /usr/local/lib/python3.10/dist-packages/langchain/document_loaders/csv_loader.py in load(self)83 raise RuntimeError(f“Error loading {self.file_path}”)from e 84 except Exception as e:-> 85 raise RuntimeError(f“Error loading {self.file_path}”)from e 86 87 return docs
RuntimeError:Error loading /content/testing.csv

如果没有看到你的代码,这有点困难,但这里有一个建议:让python在使用CSV模块时用Unicode替换符号替换无效字符:
字符串
神奇的是
errors='replace'
