C contiguous stride not working for the example

[Jinghong-Zhang]

Hi cuquantum team, I am trying to play around with the example python/samples/cutensornet/tensornet_example.py, and I wonder if I can use the C-contiguous arrays for the optimization of contraction paths and also the actual contraction. To do this, I just replaced
strides_in = (0,0,0,0) with strides_in = (A_d.strides, B_d.strides, C_d.strides, D_d.strides) and also

desc_net = cutn.create_network_descriptor(handle,
    num_inputs, num_modes_in, extents_in, strides_in, modes_in, qualifiers_in,  # inputs
    nmode_R, extent_R, 0, modes_R,  # output
    data_type, compute_type)

with

desc_net = cutn.create_network_descriptor(handle,
    num_inputs, num_modes_in, extents_in, strides_in, modes_in, qualifiers_in,  # inputs
    nmode_R, extent_R, R_d.strides, modes_R,  # output
    # nmode_R, extent_R, 0, modes_R,  # output
    data_type, compute_type)

and didn't change any other thing. However, the output is:

Could you tell me what happened here or how can I use C-contiguous arrays in this example instead of F-contiguous? Thanks in advance!
