I'm trying to iteratively save about 1000 images. Each image is a picture of a graph from networkx. The problem is that after about 500 images my computer crashes from memory overload.
The loop looks something like:
for subgraph in chosen_subgraphs:
plt.figure(figsize=(10,10))
pos = nx.spring_layout(subgraph)
nx.draw(subgraph, pos, edge_color='black', width=2, linewidths=1,
node_size=1500, node_color='pink', alpha=0.9, font_size=10,
labels={node: node for node in subgraph.nodes()})
nx.draw_networkx_edge_labels(
subgraph, pos,
edge_labels = labels,
font_color='red', font_size=10
)
# save network picture
plt.savefig(f'st/{k}/{counter}/network_img.png')
plt.close('all')
I found this SO question that talks about how to close a matplotlib image which I followed with plt.close('all'), but it didn't seem to work. I also tried using plt.clf() right before it, but it also didn't work.
