Hello everyone,
MxNet crashes when I run a toy example with GPU. I tried with Cuda 9.1 and
Cuda 9.2, and with mxnet 1.3.0 and 1.2.1 installed via pip. It might have to do
something with the driver version 396.54, because i am sure it worked at some
point before.
## Error Message:
```

## Minimum reproducible example
```
import mxnet as mx
from mxnet import nd, autograd, gluon
import numpy as np
print(mx.test_utils.list_gpus())
a = mx.nd.ones((2,3), mx.gpu())
print((a*2).asnumpy())
```
I have no idea what else to try.
Best,
Jack
