Error while running the grid search code

#1

I am running the grid search code as it is from Github. getting following error

C:\Users\hp\PycharmProjects\pythonCW\venv\lib\site-packages\sklearn\linear_model_logistic.py:762: ConvergenceWarning: lbfgs failed to converge (status=1):
STOP: TOTAL NO. of ITERATIONS REACHED LIMIT.

Increase the number of iterations (max_iter) or scale the data as shown in:
https://scikit-learn.org/stable/modules/preprocessing.html
Please also refer to the documentation for alternative solver options:
https://scikit-learn.org/stable/modules/linear_model.html#logistic-regression
n_iter_i = _check_optimize_result(
C:\Users\hp\PycharmProjects\pythonCW\venv\lib\site-packages\sklearn\linear_model_logistic.py:762: ConvergenceWarning: lbfgs failed to converge (status=1):
STOP: TOTAL NO. of ITERATIONS REACHED LIMIT.

Kindly suggest what changes to be made

hey @sanandasaha3 ,
it is not an error as such , it is just a warning stating that the logistic regression model that you are using more number of iteration to fit the data well. Currently it fitting , but will be providing really bad results . Or you can do is you can scale your data , it might help in convergence but it is also not sure that it will lead to convergence.

There is parameter max_iter in logistic regression , which by default 1000. You can change to here value like 10000 or 100000 , any but just greater than 1000 and see how your model performs respectively on that.

I hope this would help you.
Thank You and Happy Learning :slightly_smiling_face:.
