@<1523701205467926528:profile|AgitatedDove14> I think there is no chance to pass config.pbtxt as is.

https://github.com/allegroai/clearml-serving/blob/main/clearml_serving/serving/preprocess_service.py#L358C9-L358C81

In this line, function use self.model_endpoint.input_name (and after that input_name , input_type and input_size ), but there are no such attributes (see endpoint config above) in endpoint - they are in auxiliary_cfg string field

If I understand correctly, we can not use config.pbtxt as I used above, and we have to define inputs and outputs like in clearml-serving examples, and use config.pbtxt only for additional parameters like max_batch_size
