Hi! Thanks for the nice package. I was quite new to Tensorly Quantum and Tensorly. I just installed it on my macbook pro (M1 chip), and my virtual environment for it is as follows:
python version=3.10.16
torch version=2.7.0 (the latest as of Apr, 2025)
But then I got the error as follows:
A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.2.5 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.
If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

device: torch.device = torch.device(torch._C._get_default_device()), # torch.device('cpu'),

I think the error is only in the transformer.py? It does not affect the example of multibasis encoding though.
Thanks!
