Colabs don't seem to work

[hamzamerzic]

I cannot get the Colabs to run on https://colab.research.google.com.

I had to replace

!pip install https://github.com/deepmind/gemma

with

!pip install "git+https://github.com/google-deepmind/gemma.git"

as the former repository does not exist.

I am still unable to get the versions to match for the code to run. Also, Google provides a free TPU tier for Colab so it would be great if the code could be adapted (or some notes included) to run it on TPU as well as GPU.

After fixing the gemma install and updating the JAX import as:

!pip install -U "jax[tpu]" -f https://storage.googleapis.com/jax-releases/libtpu_releases.html

the code ends up failing with the following stack trace:

---------------------------------------------------------------------------

Adding:

!pip install -U orbax
!pip install -U chex

in addition to the import changes suggested in the issue seems to make the gsm8k_eval.ipynb imports work. I guess now we just need to wait for parameter and vocab checkpoints to become available.

Hi @hamzamerzic,

I understand you're facing issues running Colab notebooks that require the Gemma model and potentially using TPUs for acceleration. Here's a breakdown of the steps to get you started:

1. Install Latest Google Cloud TPU Libraries: !pip install -U "jax[tpu]" -f https://storage.googleapis.com/jax-releases/libtpu_releases.html This command installs the latest libraries needed to interact with Google Cloud TPUs through JAX.

2. Verify TPU Availability:

   
   import jax.tools.colab_tpu
   import jax

jax.tools.colab_tpu.setup_tpu() print(jax.devices())

Running this code snippet will attempt to set up the TPU runtime and then print the available TPU devices in your Colab environment. 

3. Install Gemma Model:
`!pip install git+https://github.com/google-deepmind/gemma.git`

Additional Resource:

- This Colab notebook  [gist](https://colab.sandbox.google.com/gist/selamw1/04dc59eea35366e8b417d0ed501f53c9/gemma_inference_on_tpus.ipynb#scrollTo=F2gYnt9Uqj8M) demonstrating Gemma inference on TPUs might be helpful.

@selamw1 I liked your colab! that would be a nice recipe for the Gemma cookbook: goo.gle/gemma-cookbook

For future users, we have some more tutorials using JAX + Gemma here: ai.google.dev/gemma

[selamw1]

Great thanks @gustheman

This PR added two new tutorials:

• gemma_inference_on_tpu: Demonstrates basic inference with Gemma on TPUs.

• gemma-data-parallel-inference-in-jax-tpu: Showcases data-parallel inference for faster processing on TPUs using JAX.
