I got this error when trying to run:
```
def test_copysign():
A = np.ones((INT_OVERFLOW, 2))
A.attach_grad()
with mx.autograd.record():
B = np.copysign(A, -1)
print(B)
assert B.shape == (INT_OVERFLOW, 2)
B.backward()
assert A.grad.shape == (INT_OVERFLOW, 2)
```
However, this was able to run with no problem:
```
@use_np
def test_copysign():
A = np.ones((INT_OVERFLOW, 2))
#A.attach_grad()
#with mx.autograd.record():
B = np.copysign(A, -1)
print(B)
assert B.shape == (INT_OVERFLOW, 2)
#B.backward()
#assert A.grad.shape == (INT_OVERFLOW, 2)
```
Am I doing this wrong?
