install problem #6
Description
Hey,
While working in orange3env in linux
I tried both via the options/add-ons and via 'pip install https://github.com/biolab/orange3-recommendation/tarball/0.1.3' installing the add-on
But when i open one of the two examples 'Baselines (recommendation)' or 'Latent factor models':
I get the warning:
Errors occurred while loading the workflow.
There were problems loading some of the widgets/links in the workflow.
Details:
ValueError("'Predictor' is not a valid output channel name for 'Baselines'.",)
and in the command line i get many error messages while it loads the example:
....(most is a repetition of the following:)
