How to display PyTorch Tensor's value without its properties?

Hello,

When I run the following MATLAB code to define a tensor variable from PyTorch,

clear all; format compact
pe = pyenv();
a_tensor = py.torch.tensor([1, 2]);
a_tensor

MATLAB's output is as below:

a_tensor = 
Python Tensor with properties:
    T: [1x1 py.torch.Tensor]
    data: [1x1 py.torch.Tensor]
    device: [1x1 py.torch.device]
    dtype: [1x1 py.torch.dtype]
    grad: [1x1 py.NoneType]
    grad_fn: [1x1 py.NoneType]
    is_cpu: 1
    is_cuda: 0
    is_ipu: 0
    is_leaf: 1
    is_maia: 0
    is_meta: 0
    is_mkldnn: 0
    is_mps: 0
    is_mtia: 0
    is_nested: 0
    is_quantized: 0
    is_sparse: 0
    is_sparse_csr: 0
    is_vulkan: 0
    is_xla: 0
    is_xpu: 0
    itemsize: [1x1 py.int]
    layout: [1x1 py.torch.layout]
    name: [1x1 py.NoneType]
    names: [1x1 py.tuple]
    nbytes: [1x1 py.int]
    ndim: [1x1 py.int]
    output_nr: [1x1 py.int]
    real: [1x1 py.torch.Tensor]
    requires_grad: 0
    retains_grad: 0
    shape: [1x1 py.torch.Size]
    volatile: 0
  tensor([1., 2.])

The last line of the output shows actual values of the PyTorch tensor variable, but MATLAB shows all the properties of the tensor variable together.

Is there a way not to show the properties when I call the tensor variable name?

You can consider using tolist method. Converting a tensor to list will only leave the values in a list format.

clear all; format compact
pe = pyenv();
a_tensor = py.torch.tensor([1, 2]);
a_tensor.tolist()
