这个问题与很多与警告有关的问题非常相似 RuntimeWarning: invalid value encountered in greater/less/etc

但是,我找不到解决我特定问题的方法,我认为应该有一个.

所以,我有一个numpy.ndarray类似于这个:

array([[ nan,   1.,  nan, ...,  nan,  nan,  nan],
       [ nan,  nan,  nan, ...,  nan,  nan,  nan],
       [ nan,  nan,  nan, ...,  nan,  nan,  nan],
       ..., 
       [ nan,  nan,  nan, ...,  nan,  nan,  nan],
       [ nan,  nan,  nan, ...,  nan,  nan,  nan],
       [ nan,  nan,  nan, ...,  nan,  nan,  nan]])

我想计算array > 0.5,它给出了我想要的结果,但是有与之比较的警告nan:

__main__:1: RuntimeWarning: invalid value encountered in greater
Out[68]: 
array([[False,  True, False, ..., False, …
