Below is the code which can be used to create a tensor with one values:

`torch.zeros(j, k)`

Example:

`torch.ones(4, 2)`

With the above example, we created a tensor of 4×2 size with one values.

Complete sample code:

```
import torch
my_tensor = torch.ones(4, 2)
print(my_tensor)
```

Output:

```
tensor([[1., 1.],
[1., 1.],
[1., 1.],
[1., 1.]])
```
