with code "tree_r_f=tree.subtree_reconfigure_forest(progbar=True)", I enconter the problem " AttributeError: 'ProcessPoolExecutor' object has no attribute 'scatter' ", could you please help me ?

Ah this is because the parallel options was changed to True by default and the default pool to use was changed away from 'dask'/'ray'. As a workaround you should be able to do any of the following:

tree_r_f = tree.subtree_reconfigure_forest(progbar=True, parallel=False)
tree_r_f = tree.subtree_reconfigure_forest(progbar=True, parallel='ray')
tree_r_f = tree.subtree_reconfigure_forest(progbar=True, parallel='dask')

and I will look into fixing more permanently.
