Torch.cuba.is_available() returns false in jupyter notebook

I used Jupiter notebook (azure notebook&ibm Jupiter lab),it both returned FALSE when I tried torch.cuba.is_available().
My torch version is 1.0.1, python version is 3.6.
And I both tried pip and conda to install torch.
Is that due to Jupiter notebook cannot dispatch GPU?

Are you using free version of these clouds?
The free version of jupyter on those clouds are without GPUs so torch.cuda.is_available() is returning False.

It is not true which jupyter cannot dispatch GPU, because it is just a interface on Ipython which is python itself.
