TypeError: A sparse matrix was passed, but dense data is required. Use X.toarray() to convert to a dense numpy array.

Hey Sathvik,
Thank you for this code! I was trying to follow it and apply it to some data I have, but I stumbled upon one error I receive. When running the line basicmodel2 = basicmodel2.fit(basictrain2, train["Label"]) I receive the error:

TypeError: A sparse matrix was passed, but dense data is required. Use X.toarray() to convert to a dense numpy array.

I'm using Python 3. Could you please help me to overcome this? Thank you!

Use .todense() to convert to a dense numpy array.
