When getting a block, can we also get the corresponding quantum numbers?

The parameter `keepdim` in `Svd_truncate` should have a default value (which can be the largest integer) so that users can use only `cutoff` to decide the truncated weight.

UniTensor.combineBonds should have an underscore

1

The function `UniTensor.combineBonds` changes the tensor so there should be an underscore in the function name.

I suggest not printing all the elements if the tensor has too many elements. I am not sure what is the best way to print it though.

matplotlib show() Segmentation fault when cytnx is imported

6

I have a strange error. If I import cytnx, I got Segmentation fault when using matplotlib show(). This happened for either build-from-scratch or conda build. See a demo as follows...

Lanczos_Gnd -> Tridiag error

1

When doing DMRG, from time to time the program is stopped and I got the following message: ``` [WARNING] Lanczos_Gnd -> Tridiag error: Lanczos continues automatically. # Cytnx warning occur...

We like to support slicing on symmetric UniTensor.

We need a Combiner to combine and split bonds.

I hope we can use Network but keep the final memory layout for the input tensors, so that we don't need to move memory in every call. This is useful...

[ToDo] AutoMPO

We will need a simple way to create an MPO from the physical operators, similar to AutoMPO in ITensor.
