exog does not have full column rank. model estimation irrespective of the numerical accuracy of coefficient estimates, set check_rank=False

Question

I have a list of companies A-Z, and I have a time data with month and year. I was able to conduct pooledOLS, FE and RE for yearly data, but now I have to do monthly analysis, meaning 01-2020, 02-2020... But everytime I run the model code I get the error : exog does not have full column rank. If you wish to proceed with model estimation irrespective of the numerical accuracy of coefficient estimates, you can set check_rank=False.
