NebulaGraph NetworkX (ng_nx) is a tool that allows you to use the NetworkX API for manipulating graphs in NebulaGraph. It makes it easy to analyze and manipulate graphs using NebulaGraph's advanced capabilities while still using the familiar NetworkX interface. In short, ng_nx bridges the gap between NebulaGraph and NetworkX.
## Quick Start
### Install
```bash
pip install ng_nx
```
### Run Algorithm on NebulaGraph
```python
from ng_nx import NebulaReader
from ng_nx.utils import NebulaGraphConfig
import networkx as nx
config = NebulaGraphConfig()
reader = NebulaReader(
space="basketballplayer",
edges=["follow", "serve"],
properties=[["degree"], ["start_year", "end_year"]],
nebula_config=config, limit=10000)
g = reader.read()
pr = nx.pagerank(
g, alpha=0.85,
max_iter=100,
tol=1e-06,
weight='degree')
import community as community_louvain
ug = g.to_undirected()
louvain = community_louvain.best_partition(ug)
```
### Write Result to NebulaGraph
#### Create Schema for the result writing
```ngql
CREATE TAG IF NOT EXISTS pagerank (
pagerank double NOT NULL
);
CREATE TAG IF NOT EXISTS louvain (
cluster_id int NOT NULL
);
```
```python
from ng_nx import NebulaWriter
pr_writer = NebulaWriter(data=pr, nebula_config=config)
# properties to write
properties = ["pagerank"]
pr_writer.set_options(
label="pagerank",
properties=properties,
batch_size=256,
write_mode="insert",
sink="nebulagraph_vertex",
)
# write back to NebulaGraph
pr_writer.write()
# write louvain result
louvain_writer = NebulaWriter(data=louvain, nebula_config=config)
# properties to write
properties = ["cluster_id"]
louvain_writer.set_options(
label="louvain",
properties=properties,
batch_size=256,
write_mode="insert",
sink="nebulagraph_vertex",
)
louvain_writer.write()
```
