KeyError while using seaborn plotting about data-analysis-and-machine-learning-projects

[mgudipati-saven]

It is fixed when I changed the header to be 'species' instead of 'class'. May be 'class' is a keyword?

Are you using different copies of the iris data sets? I have local copies in the notebook that use class as the class label column.

Your data file does not contains column labels. Use firs row is as column label. Like:

sepal_length_cm | sepal_width_cm | petal_length_cm | petal_width_cm | class|
