Hi @mmcky,

I think the build error is caused by an import naming issue in this PR:
pyro-ppl/numpyro#2052

This is due to a change in imports in the latest release of jax:
https://github.com/jax-ml/jax/releases/tag/jax-v0.7.0

Currently, we install the packages using:

!pip install numpyro jax

so it pull the latest one with naming change.

I suggest we temporarily pin an earlier version of jax until the issue is fixed upstream, and then revert to the latest version afterward.

Please let me know if that sounds good to you.

@HumphreyYang which lecture is the install happening? I have added the no-execute tag to the jax installs as JAX is setup by our build scripts -- but it is good to have in place to remind others to install those packages (when they download a notebook or use collab).

I will pin to jax==0.6.2 for now.

[mmcky]

@HumphreyYang that seems to fix the execution error. Spot on.

Please review and merge when you're ready.

Many thanks @mmcky! I am doing another set of simulations in this PR. My ETA for the merge is tomorrow morning!

@HumphreyYang I see this had a green tick but the publish workflow has execution failures.

[HumphreyYang]

Hi @mmcky, did we pin pip install --upgrade "jax[cuda12-local]==0.6.2 in the publishing script?

[mmcky]

@HumphreyYang I just arrived at the same conclusion. Let me open a quick PR to fix.
