could it be that you have a DAT in your network called ‘numpy’ as well? it seems that its looking for ‘/project1/numpy’. Btw, numpy is by default included, so you dont need to import it.

Thank you timgerritsen,it can work when I created a containter and rename to numpy, btw why can remove to import numpy? you can see I need use np.onse or np.zores, if I don’t import numpy as np, the np will be not definited, so how about you?
