This can have a lot of reasons. You'll need to check you jupyter logs to find out more.

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.0.2 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.

then the kernel died and restart， i try to change numpy‘s version，and then it has no error but died directly。

To me this looks a bit like your conda environment is corrupted, possibly by repeatedly installing new packages into it via pip.

I strongly recommend you start creating separate virtual environments for each project. By using the nb_conda_kernels package, these venvs will appear as different kernels in jupyter lab.
