Is there a simple way to label encode without using pandas for multiple columns?

Like using only numpy and sklearn's preprocessing.LabelEncoder()

    AFAIK you would need to loop through your columns and convert each string column using LabelEncoder Commented Jun 5, 2017 at 9:56

One solution would be to loop through the columns, converting them to numeric values, using LabelEncoder:

le = LabelEncoder()

cols_2_encode = [1,3,5] 

for col in cols_2_encode:
    X[:, col] = le.fit_tramsform(X[:, col])
