Hi @ptrblck, @albanD
It keeps happening with pytorch 1.4 and driver 440.
I discovered something iteresting.
It does happed going from GTX1080Ti to P6000 but not the other way around.
import torch
a=(torch.rand(70,1,256,256)>0.5).float().cuda(1)
b=a.cuda() 

So this fails
import torch
a=(torch.rand(70,1,256,256)>0.5).float().cuda()
b=a.cuda(1)

But this works
