[bug] navigation_graph

[tomasparks]

When I run navigation_graph on a dataset I get

/home/opensfm/OpenSfM/bin/navigation_graph /home/opensfm/data/berlin/

Traceback (most recent call last):
File "/home/opensfm/OpenSfM/bin/navigation_graph", line 299, in
rec_graph = create_optical_center_graph(recs, data.config)
File "/home/opensfm/OpenSfM/bin/navigation_graph", line 147, in create_optical_center_graph
optical_centers = np.vstack(optical_centers)
File "<array_function internals>", line 5, in vstack

return _nx.concatenate(arrs, 0)
File "<array_function internals>", line 5, in concatenate
ValueError: need at least one array to concatenate
