如何将数组中的零转换为南?
How to convert Zero to Nan in the array?
我使用了 temp[temp==0] = np.nan
,但我得到了这个错误:
IndexError: 2-dimensional boolean indexing is not supported.
我会使用 where
,以避免不得不下降到 numpy:
In [35]: d
Out[35]:
<xarray.DataArray (dim_0: 2, dim_1: 3)>
array([[0, 1, 2],
[3, 4, 5]])
Dimensions without coordinates: dim_0, dim_1
In [36]: d.where(d != 0)
Out[36]:
<xarray.DataArray (dim_0: 2, dim_1: 3)>
array([[nan, 1., 2.],
[ 3., 4., 5.]])
Dimensions without coordinates: dim_0, dim_1
必要时会自动移动到浮动。
