[英]I'm having trouble trying to read the numbers (0 - 10) into a list in Python 3 using CSV file and in a column format.
[英]I'm having trouble with code on PyCharm. I'm trying to read a csv file but I'm getting a unicode error where it can't read specific bytes in positions
我的代码如下所示:我使用 PyCharm 作为我的 IDE,我使用的 csv 文件来自 MS Excess。 我已将 csv 编码为 UTF-8。 我正在尝试使用 pandas 读取文件。 当我调用 df.info() 时,我希望能够区分对象和整数这也是我没有将其更改为“latin-1”或“ISO ...”的原因
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
plt.style.use('fivethirtyeight')
cols = ['sentiment','id','date','query_string','user','text']
df = pd.read_csv("trainingandtestdata\\training.1600000.processed.noemoticon.csv", header=None,
names=cols, encoding='utf-8')#low_memory=False dtype='unicode' encoding='latin1'
df.head()
df.info()
df.sentiment.value_counts()
我的错误如下所示:
如何修复 position xxxx 到 xxxx 中无法解码的字节?

当您在read_csv
方法中使用encoding='utf-8'
时,您的文件没有utf-8
编码格式。 使用其他编码方法来帮助您解决问题,例如'latin'
或'ISO-8859-1'
。 我向您推荐此链接以寻求帮助。
最坏的情况,如果这些都不起作用,您可以在'rb'
模式下读取文件( open(file, 'rb')
)并通过使用 csv 分隔符拆分每一行数据来自己解析它!
我遇到了同样的问题,但就我而言,解决方案非常简单。 My ide is PyCharm 2020.1 and the.csv have the iso-8859-1 encoding, I've tried everything without luck, so I decided to check my ide config. 我去了:
最好将 csv 保存到 xlsx 中并读取为
pd.read_excel
