I am using Enterprise Miner to train a Logistic Regression Model. In my dataset, there is a nominal attribute which has 513 classes. So, the training was not performed since it exceeded 512. Then, I followed the instruction to change the EM_TRAIN_MAXLEVELS to 550, I also added "%let EM_TRAIN_MAXLEVELS = 550" in Project Start Code. I used a new Regression node to run the flow, but it still didn't work. This time the error is "Error: Maximum target levels of 550 exceeded."
What am I supposed to do?
