"Collaborative Filtering on Google Analytics data" lab fails with `NotImplementedError: Cannot convert a symbolic Tensor (cond_1/strided_slice_4:0) to a numpy array.` #2441

MrCsabaToth · 2023-09-13T19:43:06Z

Just like the lab in #2439 this one (https://www.cloudskillsboost.google/course_sessions/2920313/labs/325084) is also part of the recommendation course (of the Professional Machine Learning Engineer Path), and also uses 1.15 TF. It set off on the right foot by using a CLI command to instantiate the Vertex AI Workbench Anaconda VM, since 1.15 TF is not selectable on the User Managed Notebook creation GUI any more.

The notebook spews warnings left and right (which we can usually ignore), but it failed at the Run as a Python module step's gcloud ai-platform local train CLI step. The root cause looked to be NotImplementedError: Cannot convert a symbolic Tensor (cond_1/strided_slice_4:0) to a numpy array.

This is the second recommendation lab which fails, it needs revision for newer TF. Unfortunately I'm way to busy with work and trying to go through the course material to rewrite these notebooks.

One more thing, the gcloud notebooks instances create tensorflow-notebook --vm-image-project=deeplearning-platform-release --vm-image-family=tf-1-15-cpu --machine-type=n1-standard-1 --location=us-central1-a which instantiates the Anaconda VM failed 3 times on me (so three times is not the charm). I modified the us-central1-a location to us-central1-b. I think this should not have affected this bug, given that this is a VM.

I just tried the solution ipynb to rule out if I mistyped something, but that fails with the exact same exception.

Lab URL BTW: https://www.cloudskillsboost.google/course_sessions/2920313/labs/325084

I've found something, this was very sneaky! The bug is not in the notebooks, but rather in the prepared walsmodel package sources. There's a difference between the lab's and the solution's walsmodel/model.py!!! The lab's have an extra export_strategies parameter and a whole function for the tf.contrib.learn.Experiment(. This must cause the error, because going with the solution's prepared module the lab didn't fail!

Based on that I'll be able to produce another fix PR!
