Re: [graph-tool] TypeError while using add_edge_list

[ashutosh]

I got the problem.

Graph Tool by default accepts only vertex objects or int(index) values on
edge list and hence either I pass on vertex object list or keep the options*
hashed=True and string_vals=True* in the add_edge_list option.

The problem is resolved now. Thank you

[ashutosh]

sampleFile.tab

  

above is the sample file.

and below is the code that produces the error as i mentioned before

import pandas as pd
import graph_tool.all as gtx
df = pd.read_csv("file_path",sep='\t',headers=True)

myGraph = gtx.Graph()

myGraph.add_edge_list(df.values.tolist())

Tiny typo, the first argument is `hashed=True`.

Re: [graph-tool] TypeError while using add_edge_list

[Alexandre Hannud Abdo]

Ni! Hi ashu,

Please, always try to *read errors carefully* and consult the
documentation. Not to mention, provide self-contained examples.

Python is throwing a "TypeError" and telling you it expects an integer
('unsigned long', the C++ type for vertex indices) while you are passing it
a string ('str').

As you can see in the documentation
, if you want to
pass strings to add_edge_list you should set two additional arguments:
`hash=True` and `string_vals=True`.

If that doesn't fix it, you'll have to provide a self-contained example
where the error occurs, otherwise we can't really help.

You have to pass the option "layers=True" to the LayeredBlockState constructor:

https://graph-tool.skewed.de/static/doc/inference.html#graph_tool.inference.layered_blockmodel.LayeredBlockState

Yes, it accepts 'recs/rec_types/rec_params' just like the regular BlockState.

Best,
Tiago

[graph-tool] TypeError while using add_edge_list

[ashutosh]

Hi,

I'm trying to convert two columns of my pandas dataframe into network using
them as edge list.
A  similar query

  
was posted in StackOverflow but with different problem and it didn't help
me.

When I am trying the following code it gives me error:
*
myGraph.add_edge_list(i for i in df[['node1','node2']].values.tolist())*

Where, my Graph is the graph;  df is the dataframe with 4 columns out of
which I am using two 'node1' and 'node2'.

*File "/usr/lib/python3/dist-packages/graph_tool/__init__.py", line 2109, in
add_edge_list
libcore.add_edge_list_iter(self.__graph, edge_list, eprops)*

*TypeError: No registered converter was able to produce a C++ rvalue of type
unsigned long from this Python object of type str
*


I tried upgrading my boost library but it doesn't solve the problem. Any
suggestions ?
