calamari-predict: Exception, when prediction is 0%

[stefanCCS]

Version 2.1.5
It looks like that calamari-predictraises an exception, when a prediction value of 0% is recognized:

Prediction:   0%|                                                                                                                                                                    | 0/13 [00:00<?, ?it/s]2022-02-24 13:18:22.349295: I tensorflow/compiler/mlir/mlir_graph_optimization_pass.cc:116] None of the MLIR optimization passes are enabled (registered 2)
