遇到個(gè)小白常見(jiàn)的問(wèn)題,發(fā)現(xiàn)度娘里面沒(méi)有記錄,翻墻谷歌了下,解決問(wèn)題,在此寫個(gè)說(shuō)明。
事情起因:
在jupyter notebook中導(dǎo)入文件時(shí)發(fā)生了錯(cuò)誤:

出現(xiàn)這個(gè)問(wèn)題是因?yàn)榻忉屍髡也坏綄?duì)應(yīng)的文件。念了“媽咪媽咪轟”pwd后,發(fā)現(xiàn)問(wèn)題所在:
pwd顯示當(dāng)前目錄不是該文件所在的目錄。這下明白了,使用咒語(yǔ)要謹(jǐn)慎,記得在念“媽咪媽咪轟”load前,要cd到該文件的目錄下去。

補(bǔ)充:Jupyter Notebook - sns.load_dataset加載文件錯(cuò)誤解決方法
seaborn模塊中sns.load_dataset加載文件錯(cuò)誤解決方法:
import seaborn as sns
data = sns.load_dataset("iris")
出現(xiàn)錯(cuò)誤:
URLError: urlopen error [Errno 11004] getaddrinfo failed>
出現(xiàn)原因:
seaborn-data文件夾里面是空的,可以另外下載該文件夾的內(nèi)容復(fù)制到該文件夾中。
下載地址:
https://github.com/mwaskom/seaborn-data
下載位置:
電腦上搜索seaborn-data文件夾
將下載下來(lái)的文件解壓后全部放進(jìn)seaborn-data文件夾
重新運(yùn)行代碼,出現(xiàn)結(jié)果。
以上為個(gè)人經(jīng)驗(yàn),希望能給大家一個(gè)參考,也希望大家多多支持腳本之家。如有錯(cuò)誤或未考慮完全的地方,望不吝賜教。
