Could you tell me how to deal with this problem?

When i run network.py,there will arise this problem.

我也有同样的问题，networkx.exception.NodeNotFound: Either source 0.750|2.250 or target -1.500|0.250 is not in G，请问您解决了吗？

您好，我之前没遇到过这个问题，我想这个可能和：（1）AI2-THOR version有关；（2）能不能通过加段代码，排除这两个位置（0.750|2.250 or target -1.500|0.250）来解决这个问题？
