When inferencing of test data it would be nice to display accuracy rate for that dataset.
Yes. we have considered this in the past as well as a useful feature. This would be applicable only for validation/training set where labels are available to calculate accuracy.
Do you mean that the Test Dataset in DLS is meant to have no label ?
Yes. We dont expect user has labels when uploading dataset for inference (or even when test dataset is split of training dataset). test.csv file can be uploaded with or without the label column data.
