hey @bhavyahoda,
can you briefly tell what actually the problem are you facing in loading the dataset ?
Doubt regarding dataset
in the line
sns.load_dataset(“tips”) I am getting an error
means I am not able to import the dataset using this thing whereas in the video bhaiya has done this only why is it so
what error particularly does it shows?

I am working on Macos X
yes I have proper internet
python 3.8
but I do not know about ssl module what is it?
I have tried reinstalling seaborn also but still stuck up
can u tell me how to remove this ssl certification error
try running this
import ssl
import urllib2
ssl._create_default_https_context = ssl._create_unverified_context
and after this your code
let me know the output of this
ModuleNotFoundError Traceback (most recent call last)
in
1 import seaborn as sns
2 import ssl
----> 3 import urllib2
4 #ssl._create_default_https_context = ssl._create_unverified_context
ModuleNotFoundError: No module named ‘urllib2’
okaay , just remove that line for now.
only use
import ssl
ssl._create_default_https_context = ssl._create_unverified_context
do you have urllib3 installed ,
check this by
import urllib3
yeah now I am able to do so but what was the problem can u pls explain
so is it properly loading dataset now?
no I do not have urllib3 also
yes
it is loading the dataset properly
I have printed the dataset also.
Kindly install it , it will useful in future with other packages
yeah I have downloaded it now
thanks for ur support
So the error , was about a SSL certificate , which is something like preparing a secured connection to download something , which seaborn makes. But due to some reasons ,it wasn’t able to do so. Hence you were getting this error.
Glad to hear this.
I would request you to kindly mark this doubt as resolved and also provide you valuable feedback as as it helps us to improve this platform and provide you with better learning experience.
Thank You and Happy Learning 
.
