I am on Ubuntu 16.10. I am trying to download an image using urlretrieve() function of python. I am getting the following errors.
File "downloadImage.py", line 9, in <module>

Also my code is :
import random
import urllib
def downloadWebImage(url):
name = random.randrange(1,1000)
fullName = str(name) + '.jpg'
urllib.urlretrieve(url, fullName)
downloadWebImage("https://qph.ec.quoracdn.net/main-qimg-601accaf841bba9145d3c46bece1ea10-p")
So what are the errors, why are they occuring? What is their fix?

I'm trying to upload example from dash documentation.
When I try (with PyCharm)
df = pd.read_csv(
'https://raw.githubusercontent.com/plotly/datasets/master/solar.csv'
)
I get these errors.
But when I try the same code with Anaconda Jupyter it works fine. It means problem is not in my OS but in PyCharm.
Can you advise what should I do?

I think you should check whether you're using the same Python interpreter and Pandas version in both Jupyter and PyCharm.
Find Jupyter interpreter: How to know which Python is running in Jupyter notebook?
(Check this if using Spyder: https://docs.spyder-ide.org/current/faq.html#using-existing-environment)
Check if it's the same in PyCharm: https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#interpreter
If possible point the solution as well

Try this it works for me:
import random

def download_web_image(url):
name = random.randrange(1,1000)
fullname = str(name) + ".jpg"
urllib.request.urlretrieve(url, fullname)
print(download_web_image("https://upload.wikimedia.org/wikipedia/commons/b/b4/JPEG_example_JPG_RIP_100.jpg"))
This outputs: None but it's fine!
The file is saved in the same directory as the script.
Here is the way I ran the script:
you just have to use the command:

I don't know how to solve this issue. Maybe it's because I worked behind a proxy? If so, how to make urllib.urlretrieve work behind the proxy?
Add proxy settings to your global environment to see if it fixes the problem.
sudo gedit /etc/environment
Then add these two lines
http_proxy=http://your_proxy.com:443
https_proxy=https://your_proxy.com:443
