出现了这个错误是啥原因呢 Traceback (most recent call last): File "E:\FY3-Reader-master\FY3-Reader-master\test.py", line 36, in mwri_l1.crop((25, 35, 135, 145)) File "E:\FY3-Reader-master\FY3-Reader-master\fy3Reader\mwri_base.py", line 97, in crop yi, yj, xi, xj = self._get_indices(ll_box) File "E:\FY3-Reader-master\FY3-Reader-master\fy3Reader\mwri_base.py", line 52, in _get_indices yi, yj = np.amin(barrind_y), np.amax(barrind_y) File "<__array_function__ internals>", line 200, in amin File "D:\admin\envs\fy3d3d\lib\site-packages\numpy\core\fromnumeric.py", line 2946, in amin return _wrapreduction(a, np.minimum, 'min', axis, None, out, File "D:\admin\envs\fy3d3d\lib\site-packages\numpy\core\fromnumeric.py", line 86, in _wrapreduction return ufunc.reduce(obj, axis, dtype, out, **passkwargs) ValueError: zero-size array to reduction operation minimum which has no identity

mwri_l1.crop((25, 35, 135, 145))的含义是按照纬度25N\~35N，经度135E\~145E的范围对从文件读取到的数据进行裁剪。您可以检查一下裁剪的区域是不是在读取的文件的范围里。

img_extent = (135, 145, 20, 30)这个函数是干什么的呢
