With your sym3 example, here is what I got with MXNet 1.9 on Linux. Not sure
if this issue only occurs on Windows. Did you @matteosal try it on Linux?
```
Input1 + Input2 gradient, CPU (OK):
{'.Inputs.Input1': 'write', '.Inputs.Input2': 'write', '.Inputs.Input3':
'null'}
[23:37:54] ../src/storage/storage.cc:199: Using Pooled (Naive)
StorageManager for CPU
[[[-3. -2. -3. -3.]
[ 0. -3. -1. -3.]]]
<NDArray 1x2x4 @cpu(0)>
Input1 + Input2 gradient, GPU (OK):
{'.Inputs.Input1': 'write', '.Inputs.Input2': 'write', '.Inputs.Input3':
'null'}
[23:38:01] ../src/storage/storage.cc:199: Using Pooled (Naive)
StorageManager for GPU
[[[-3. -2. -3. -3.]
[ 0. -3. -1. -3.]]]
<NDArray 1x2x4 @gpu(0)>
Input2 gradient only, CPU (OK):
{'.Inputs.Input1': 'null', '.Inputs.Input2': 'write', '.Inputs.Input3':
'null'}
[[[-3. -2. -3. -3.]
[ 0. -3. -1. -3.]]]
<NDArray 1x2x4 @cpu(0)>
Input2 gradient only, GPU (WRONG):
{'.Inputs.Input1': 'null', '.Inputs.Input2': 'write', '.Inputs.Input3':
'null'}
[[[-3. -2. -3. -3.]
[ 0. -3. -1. -3.]]]
<NDArray 1x2x4 @gpu(0)>
