Error during model fit in machine learning

Question

When I am trying to fit my model on X_train and y_train, it gives me an error as shown in the image. The term Alberta is one of the entry in the province column of the dataset. Here i am using Decision Tree and Random forest as it is an unbalanced dataset. Please help me to resolve this error. I don't know where am i going wrong..

Answer 1

This probably happens because you have both numerical values and strings in the dataset. Some solutions I would suggest are:

• Go through the dataset and drop unnecessary features/columns (be careful that you won't drop important features).
• Convert the categorical type columns into numeric to get rid of strings.
