Error when training a model via the lab

Hello, I am coming to you because I have an error when training a classification model via the dataiku lab. During the training of the model I get the following error:

[2020/03 / 18-13: 32: 01.564] [MRT-2928] [WARN] [dku.analysis.ml.python] - Training failed

If anyone has the answer to my question it would be great!
