10 Minutes to Pandas tutorial - to_numpy() does not exist?

To check your version of pandas

import pandas as pd
print(pd.__version__)

If it's not 0.24, you need to update pandas else you can use df.values. To upgrade pandas under Anaconda, grab Anaconda command prompt and type:

conda update pandas 

To upgrade pandas under Python3

pip3 install --upgrade pandas

One really great thing with to_numpy() method is the copy parameter it provides:

npa=df.to_numpy() #editing npa will reflect in df
npa=to_numpy(copy=True) #editing npa will not affect the df

This feature was just added in Version 0.24.0, which was released a couple of days ago. If you haven't updated yet, the attribute doesn't exist! Once you update pandas the problem should resolve itself.

Try df.values instead. This will have the same effect for versions of pandas prior to 0.24.0
