Fastai support cuda 9.2?

When I run the code below:

learn.precompute=False, 3, cycle_len=1)

GPU crashed and computer rebooted. If not run learn.precompute=False ,then, 3, cycle_len=1) will run normally.
I use my own GPU Titan Xp and Ubuntu 18.04 system and cuda9.2. pytorch 0.4.1 support cuda 9.2.

best way to avoid problems like that, is to create env using conda. You will have lots of problems like that in future. I have 3 different envs right now (one for Keras, one for Pytorch 0.4.1 and cuda 9.1, one for
