when shape is unexpected, pynio return "check dtype"

[mektpoy]

The error is:

Traceback (most recent call last):
File "interp2d.py", line 60, in
outf.variables['lat'].assign_value(ersst_lat)
File "/etc/anaconda2/envs/ml/lib/python3.8/site-packages/PyNIO/Nio.py", line 444, in assign_value
self._obj.assign_value(value)
Nio.NIOError: failed to write array (check dtype)

but acctually this caused by wrong numpy.shape

Maybe, You can check data type.I use the np.zeros find the list default type is float64 and i can not write in nc file , so i change the np.zeros dtype is float32, its OK.
