A NumPy array must have the same number of values in each row or it will raise an error, but a list or a tuple can have any number of values, so getting the shape of a list or tuple is a bit tricky. You can use the example in this tutorial to help you get the shape of a l...
Tutorials are necessary! Considering the future workload, PyPOTS tutorials are released in a single repo, and you can find them in BrewPOTS. Take a look at it now, and learn how to brew your POTS datasets!☕️ Welcome to the universe of PyPOTS. Enjoy it and have fun!
