Error in sys.excepthook:
Original exception was:
After the execution of the program.
To Reproduce
Below is a minimal example to reproduce the bug:
from mxnet import nd
import mxnet as mx
x = mx .np .zeros ((10 ,))
x .attach_grad ()
class Op (mx .autograd .Function ):
def forward (self , x ):
out = x + 1
return out
def backward (self , grad ):
grad_x = grad
return grad_x
op = Op ()
with mx .autograd .record ():
y = op (x )
y .sum ().backward ()
print (x .grad )However, it could successfully print the result
[1. 1. 1. 1. 1. 1. 1. 1. 1. 1.]
