Are you using a windows or linux system?
I have had issues with jax failing when I tried to use python 3.13 for some reason.
What I usually do with spyder is install it using the standalone spyder installer downloaded from their website.
Then run: (I use miniforge which only uses the conda-forge channel)
conda create -n pymc_env python==3.12.*
conda install pymc
conda install spyder-kernels=3.0.*
and that makes everything work. When I tried installing numpyro with python 3.13 and tried sampling with numpyro the kernel would instantly die
