Issue about TF recommenders sample

TensorFlow General Discussion
1

Hi,
When I run TF recommenders sample, it need to use Scann,code is as below:
scann_index = tfrs.layers.factorized_top_k.ScaNN(model.user_model)
if without Scann, error info will be this:

ImportError: The scann library is not present. Please install it using pip install scann to use the ScaNN layer.

But after I installed scann, error looks as this

Illegal instruction (core dumped)

version info:
tensorflow 2.8.0
tensorflow-datasets 4.5.2
tensorflow-estimator 2.7.0
tensorflow-io-gcs-filesystem 0.25.0
tensorflow-metadata 1.8.0
tensorflow-recommenders 0.6.0

Scann 1.2.5

Hi @guohua_qin, I have tried the recommenders sample model in colab and did not face any error. please refer to this gist for working code example. Could you please try with the latest version of Tensorflow if issue still persists let us know the details of the environment you are using. Thank You.

This multi-year discussion shows that many people cannot install the scann library outside of colab.

Here is the error that results for me when attempting install scann in a SageMaker notebook in a conda_tensorflow2_p310 environment:

!pip install scann
ERROR: Could not find a version that satisfies the requirement scann (from versions: none)
ERROR: No matching distribution found for scann
