How to train new data that arrives

[mahabenfares]

Hello,

I am trying to use progressive umap for data streams, can you tell me how I can train new data that arrives. At first I called the fit_transform function on the available data as you showed in the test example, and after that I called the transform function on the new data that arrives, but I have this error. Can you please explain to me how to use this library for training new data that arrives. Thanks!
