Tinyml Workshop Runtime Error

Running through the tutorial: [Nano 33 BLE Sense Rev2](https://docs.arduino.cc/hardware/nano-33-ble-sense-rev2)
Get Started With Machine Learning on Arduino

In arduino_tinyml_workshop.ipynb in Colab
Got data and uploaded to Colab.
Running the cells, got to the cell: Run with Test Data'
Runtime errors on these lines:
plt.plot(inputs_test, outputs_test, 'b.', label='Actual')
plt.plot(inputs_test, predictions, 'r.', label='Predicted')

Added in a few prints of data...

Open arduino_tinyml_workshop.ipynb in Colab and start at the “Run with Test Data” cell. Inspect the reported plotting lines alongside the printed shapes for inputs_test, outputs_test, and predictions, then rerun the cell. Done means the tutorial cell completes without the reported ValueError and displays the actual and predicted data plots.
