UnicodeDecodeError: 'utf-8'编解码器无法解码字节0x8b,位置在第1个字节处:在pandas中读取csv文件时出现无效的起始字节。

我知道类似的问题已经被提出,我已经看过所有的解答并尝试过,但效果不大。我正在使用OSX 10.11 El Capitan操作系统,python3.6版本,使用了虚拟环境,但也尝试过不使用虚拟环境。我正在使用jupyter notebook和spyder3。

我是Python的新手,但了解基本的机器学习知识,并且正在参考一篇博文学习如何解决Kaggle挑战:博文链接数据集链接

我在代码的前几行卡住了。

`

import pandas as pd
destinations = pd.read_csv("destinations.csv")
test = pd.read_csv("test.csv")
train = pd.read_csv("train.csv")

但是出现了错误

stackoverflow上的一些答案表明这是因为文件被gzip压缩,但是Chrome下载的是.csv文件,没有看到.csv.gz,并返回文件未找到错误。

然后我读到使用encoding='latin1',但是这样做后我得到了解析器错误:

我花了几个小时来调试这个问题,尝试在Atom上打开csv文件(没有其他应用程序能够打开它),在线网站应用程序(一些崩溃了),但没有帮助。我还尝试使用其他人解决问题的内核,但也没有帮助。
