Hi all,
I am trying to do some BDT studies. The old framework used uproot3. There is a line like:

all_ttrees = dict(file.allitems(filterclass=lambda cls: issubclass(cls, uproot3.tree.TTreeMethods)))

How can I replace it in uproot4? Actually, I have checked the tutorial of uproot4, but I did not understand it well.
Thank you very much!

As it is in the python section, may be @etejedor knows.

Hi @11111 ,
the ROOT team does not provide support for uproot, please refer to uproot’s own support channels.
