Current Behavior?
Running the code from this time series example does not produce the same number of parameters as the example output in the documentation. Further, the model does not achieve stated accuracy.
The colab link also has the same issue.
What is strange is that the doc's final dense layer has ~64K params while running the code produces 2x the mlp unit input, which is 128. I tried increasing it to see if that fixed the problem, but it seems that there is something structurally different between how this code runs on 2.4 vs 3.7.0.
I expected the close to the same output as what is documented on the page.
