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:

import csv
with open("your_file.csv", "r", encoding="utf-8", errors="replace") as file:
    reader = csv.reader(file)
    for row in reader:
        pass
        # Your processing logic here

字符串
神奇的是errors='replace'

下面的片段是我如何从CSV文件中读取和提取数据:

import pandas as pd

# Read CSV data into a Pandas DataFrame
data = pd.read_csv('./content/testing.csv')

# Convert DataFrame to JSON format
jsonData = data.to_dict(orient='records')

# Iterate through each row in the JSON data
for row in jsonData:
    # Your custom logic here

字符串
希望这有助于除了以上solutionMarkus
