updata numpy version according to requirement

Same problem here. Get this error when using numpy 1.19.4 in vscode AttributeError: 'float' object has no attribute 'round'

I got a similar problem. My numpy version is 1.19.4

a = 1.23

round(a,1) # this one would work

a.round(1) # this one gives me error message "AttributeError: 'float' object has no attribute 'round'"

@xieyj17 round() by itself is a python op which will be slower on numpy arrays.

@xieyj17 @seedergy where exactly in the code are you seeing this error? Can you provide a reproducible example, i.e. in our colab notebook please?
