Question

每次我尝试做任何涉及kd树的事情时，我都会出现以下错误。奇怪的是，就在几天前，这个代码工作正常，它仍然在我同事的机器上工作正常（我们使用相同的回购）。

无论我传递什么，似乎都会发生。

任何人都可以提供任何见解吗？

  File "filename.py", line 69, in methodname
    get_index = self.kd_tree.query(array_to_query)

    for c in np.ndindex(retshape):

    return array(a, dtype, copy=False, order=order)

从未找到答案，但强行重新安装numpy和scipy解决了这个问题。

Scipy kd-tree实现抛出“负面维度”
