Dear Experts,
I was trying to save results of eof analysis to an npz file and see that it is not possible to save a 3d array as npz file variable. Is this true even today or are there developments which make this possible? I am able to save all other variables except the 3d array.
with best regards,
Sudheer
eof1.shape
Out[61]: (10, 140, 180)
pc1.shape
Out[62]: (2192, 10)
x.shape
Out[63]: (140, 180)
np.savez(outf,pcs=pc1,x=x,y=y,clevs=clevs)
works fine
but below do not
np.savez(outf,eof1=eof1)
