How to get the dependency tree with spaCy?

In case someone wants to easily view the dependency tree produced by spacy, one solution would be to convert it to an nltk.tree.Tree and use the nltk.tree.Tree.pretty_print method. Here is an example:

import spacy
from nltk import Tree


en_nlp = spacy.load('en')

doc = en_nlp("The quick brown fox jumps over the lazy dog.")

def to_nltk_tree(node):
    if node.n_lefts + node.n_rights > 0:
        return Tree(node.orth_, [to_nltk_tree(child) for child in node.children])
    else:
        return node.orth_


[to_nltk_tree(sent.root).pretty_print() for sent in doc.sents]

Output:

                jumps                  
  ________________|____________         
 |    |     |     |    |      over     
 |    |     |     |    |       |        
 |    |     |     |    |      dog      
 |    |     |     |    |    ___|____    
The quick brown  fox   .  the      lazy

Edit: For changing the token representation you can do this:

def tok_format(tok):
    return "_".join([tok.orth_, tok.tag_])


def to_nltk_tree(node):
    if node.n_lefts + node.n_rights > 0:
        return Tree(tok_format(node), [to_nltk_tree(child) for child in node.children])
    else:
        return tok_format(node)

Which results in:

                         jumps_VBZ
