Generic Python-exception-derived object raised by linalg functions. General purpose Hi Team, I am trying to build and run a logistic regression model (with a very large dataset). After data cleaning, dummy creation and vif check when tried to run the model i am getting below error: Build logistic regression model (using statsmodels package/library) import statsmodels.api as sm M1 = sm.Logit(Train_Y, Train_X) # (Dep_Var, Indep_Vars) # This is model definition M1_Model = M1.fit So I tried to solve the matrix above but I couldn't.
