'int' object has no attribute 'lower' while doing tokenizer.fit_on_text(d['column_name'])

Question

tokenizer=Tokenizer(num_words=1000, split=' ')
tokenizer.fit_on_texts(d['column'].values)

x=tokenizer.texts_to_sequences(d['column'].values)

In column POS_words I have all sentences having skills (C#, Office365, ...) there are some nos. +91.

I want to convert it into array but its throwing error

AttributeError: 'int' object has no attribute 'lower'

Please tell me how to fix this

Answer 1

The issue is solved

d['column']=d['column'].astype(str)
