Tutorial Question concerning set_pois, pandana 0.3.0

[apiszcz]

the x,y variables are not defined, I tried 'x','y' and ['x','y'] which produce other pandas errors.

net.set_pois("restaurants", x, y)
produces
*** NameError: name 'x' is not defined


import pandas as pd
import pandana as pdna
store = pd.HDFStore('osm_bayarea.h5', "r")
nodes = store.nodes
edges = store.edges
print(nodes.head(3))
print(edges.head(3))
net=pdna.Network(nodes["x"], nodes["y"], edges["from"], edges["to"],edges[["weight"]])
net.precompute(3000)
net.init_pois(num_categories=1, max_dist=2000, max_pois=10)
net.set_pois("restaurants", x, y)

[apiszcz]

Are the assignments missing from the tutorial?

y=nodes.y
x=nodes.x

Hello!
The tutorial here says This code initializes the “restaurants” category with the positions specified by the x and y columns (which are Pandas Series). The tutorial does not explicitly create the x and y series but instructs you that that is what they are. In the actual code demonstration here shows the full workflow and the creation of the x and y series in code.

Will close this unless there an issue with this.
