beginner

I'm using networkx to work with graphs. I have pretty large graph (it's near 200 nodes in it) and I try to find all possible paths between two nodes. But, as I understand, networkx can find only shortest path. How can I get not just shortest path, but all possible paths?

Dear Everyone I am interested in finding a path (not necessarily shortest) in a short amount of time. Dijsktra and AStar in networkx is taking too long. Why is there no DFS or BFS in networkx?
