IPython can automatically plot the returned graphviz instance. Otherwise, you should call .render() method of the returned graphviz instance. Parameters ---------- booster : Booster or XGBModel instance fmap : The name of feature map file num_trees : Specify the ordinal number of target tree rankdir : Passed to graphviz via graph_attr yes_color : Edge color when meets the node condition. no_color : Edge color when doesn't meet the node condition. condition_node_params : Condition node configuration for for graphviz. Example: .. code-block:: python {'shape': 'box', 'style': 'filled,rounded', 'fillcolor': '#78bceb'} leaf_node_params : Leaf node configuration for graphviz. Example: .. code-block:: python {'shape': 'box', 'style': 'filled', 'fillcolor': '#e48038'} kwargs : Other keywords passed to graphviz graph_attr, e.g. ``graph [ {key} = {value} ]`` Returns ------- graph: graphviz.Source r)Sourcez&You must install graphviz to plot treeNdot graph_attrsrTedgerUrVrWrX:)r dump_format) graphvizrZr/r0r r1itemsgetjsondumpsget_dump)r rrSrTrUrVrWrXrrZrH parametersextrar%valuetreegs r! to_graphvizrksnK#'8$%%'J Elln Uc  "}+2}i(kkm U ::mT * 6).F= !# &$&F= ! 3K  4v&/v{#%-vz"(*?&'#%5!" c djj((   :  >y IDt A HM KBCJKsC== D DDc  ddlm}ddlm}||j dd\} }t |f|||d|} t } | j| jd | jd|j| } |j| |jd |S#t$r}td|d}~wwxYw) a5Plot specified tree.
