HTTP错误404：未找到urllib.request.urlretrieve

问题描述

不确定为什么在链接正常工作时会发生此错误。当我单击链接时，将被带到原始数据，但是当我运行代码时，出现404错误。

import pandas as pd
import os
import tarfile
from six.moves import urllib
DOWNLOAD_ROOT = "https://raw.githubusercontent.com/isaiahxcruz/Datasets/master/TSLA_data" 
TESLA_PATH = os.path.join("datasets","tesla")
TESLA_URL = DOWNLOAD_ROOT + "datasets/tesla/tesla.tgz"
def fetch_tesla_data(tesla_url=TESLA_URL,tesla_path=TESLA_PATH): 
    if not os.path.isdir(tesla_path):
        os.makedirs(tesla_path)
    tgz_path = os.path.join(tesla_path,"tesla.tgz") 
    urllib.request.urlretrieve(tesla_url,tgz_path) 
    tesla_tgz = tarfile.open(tgz_path) 
    tesla_tgz.extractall(path=tesla_path) 
    tesla_tgz.close()
fetch_tesla_data()

解决方法

您输入的URL错误。 TESLA_URL为https://raw.githubusercontent.com/isaiahxcruz/Datasets/master/TSLA_datadatasets/tesla/tesla.tgz

实际网址为https://raw.githubusercontent.com/isaiahxcruz/Datasets/master/TSLA_data

您在URL中添加了一些单词，使其与原始单词有所不同。

只需将您的代码修改为以下内容

import pandas as pd
import os
import tarfile
from six.moves import urllib 

TESLA_PATH = os.path.join("datasets","tesla")

# This is what I changed
# I got rid of DOWNLOAD_ROOT and just threw the link in TESLA_URL
TESLA_URL = "https://raw.githubusercontent.com/isaiahxcruz/Datasets/master/TSLA_data"

def fetch_tesla_data(tesla_url=TESLA_URL,tesla_path=TESLA_PATH): 
    if not os.path.isdir(tesla_path):
        os.makedirs(tesla_path)
    tgz_path = os.path.join(tesla_path,"tesla.tgz") 
    urllib.request.urlretrieve(tesla_url,tgz_path) 
    tesla_tgz = tarfile.open(tgz_path) 
    tesla_tgz.extractall(path=tesla_path) 
    tesla_tgz.close()

fetch_tesla_data()

,

有两个问题

• 错误的网址-仅需要DOWNLOAD_ROOT而不需要"datasets/tesla/tesla.tgz"

• 它提供原始文本（不是压缩文件），并且不需要tarfile和extractall

---

import os
from six.moves import urllib 

URL = "https://raw.githubusercontent.com/isaiahxcruz/Datasets/master/TSLA_data"
LOCAL_FOLDER = "datasets"  # or "datasets/tesla"
LOCAL_FILENAME = "tesla.csv"
LOCAL_PATH = os.path.join(LOCAL_FOLDER,LOCAL_FILENAME)

os.makedirs(LOCAL_FOLDER,exist_ok=True)
urllib.request.urlretrieve(URL,LOCAL_PATH) 

df = pd.read_csv(LOCAL_PATH)
print(df)

仅此而已。
