                Well, so ideally you would have shown more about how your data looks like (I must admit I don’t understand that exactly), but say it is similar to 
a,b,c = torch.randn(3, 2, 10) # three 2x10 tensors
arr = numpy.array([a,b,c], dtype=object) # array of size 3 of 2x10 tensors

then you can do 
t = torc…
