iloc giving 'IndexError: single positional indexer is out-of-bounds'
Solution 1:
This error is caused by:
Y = Dataset.iloc[:,18].values
Indexing is out of bounds here most probably because there are less than 19 columns in your Dataset, so column 18 does not exist. The following code you provided doesn't use Y at all, so you can just comment out this line for now.
Solution 2:
This happens when you index a row/column with a number that is larger than the dimensions of your dataframe
. For instance, getting the eleventh column when you have only three.
import pandas as pd
df = pd.DataFrame({'Name': ['Mark', 'Laura', 'Adam', 'Roger', 'Anna'],
'City': ['Lisbon', 'Montreal', 'Lisbon', 'Berlin', 'Glasgow'],
'Car': ['Tesla', 'Audi', 'Porsche', 'Ford', 'Honda']})
You have 5 rows and three columns:
Name City Car
0 Mark Lisbon Tesla
1 Laura Montreal Audi
2 Adam Lisbon Porsche
3 Roger Berlin Ford
4 Anna Glasgow Honda
Let's try to index the eleventh column (it doesn't exist):
df.iloc[:, 10] # there is obviously no 11th column
IndexError: single positional indexer is out-of-bounds
If you are a beginner with Python, remember that df.iloc[:, 10]
would refer to the eleventh column.
