When I apply GridSearchCV to my model Logistic Regression, it's continuously throwing below error. I understand that it's trying to convert string to float. But that's was my data. So how can I convert my x value to float? Can any please hep me with this issue. Thank you.

Error: could not convert string to float: 'great im readi go home'

Sample data

  • $\begingroup$ Yes you can apply it, refer the docs please.; ML models can only take in "number or numeral representations" of the same, they generally don't take raw strings as such directly, so go for a tf-idf+log reg baseline! $\endgroup$

  • $\begingroup$ Do you mean, instead of a string of do I need to apply tfidf x matrix value .? $\endgroup$

  • $\begingroup$ Yep, I would recommend checking out scikit learn examples first.. They are very well written with reusable code blocks to get you started. Your error code is very clear imho $\endgroup$

I believe that the first thing you should do is to convert your data to a numeric type.

Maybe this starter tutorial can help you https://towardsdatascience.com/introduction-to-natural-language-processing-nlp-323cc007df3d
