我知道已经问过类似的问题我已经看过所有这些问题，并尝试过但没什么帮助。我正在使用OSX 10.11 El Capitan，python3.6。，虚拟环境，尝试没有它也。我正在使用jupyter笔记本和spyder3。
我是python的新手，但是知道基本的ML并关注帖子以了解如何解决Kaggle挑战：Link to Blog，Link to Data Set
。我被困在前几行代码中 `
import pandas as pd
destinations = pd.read_csv("destinations.csv")
test = pd.read_csv("test.csv")
train = pd.read_csv("train.csv")
它给了我错误

stakoverflow上的一些答案表明它是因为它被gzip压缩，但是Chrome下载了.csv文件而.csv.gz无处可见，并且返回了找不到文件的错误。
然后我读到某个地方使用encoding='latin1'，但在这之后我得到了解析器错误：

我花了好几个小时来调试这个，试图在Atom上打开csv文件（没有其他应用可以打开它），在线网络应用程序（有些崩溃）但没有帮助。我尝试过使用其他人的内核谁解决了这个问题，但没有帮助。
答案 0 :(得分：5)
它仍然很可能是gzip压缩数据。 gzip的幻数是0x1f 0x8b，与你得到的UnicodeDecodeError一致。
您可以尝试即时解压缩数据：
with open('destinations.csv', 'rb') as fd:
gzip_fd = gzip.GzipFile(fileobj=fd)
destinations = pd.read_csv(gzip_fd)
答案 1 :(得分：1)
您可以尝试使用编解码器
import codecs
with codecs.open("destinations.csv", "r",encoding='utf-8', errors='ignore') as file_dat:
destinations = pd.read_csv(file_data))
答案 2 :(得分：1)
在读取 csv 文件时尝试包含此编码
pd.read_csv('csv_file', encoding='ISO-8859–1')
